In order to overcome various problems in the process of experimentation, Cheng Nuo specially set up a research team to concentrate on solving various obstacles.

In the previous way, the method of iron oxide was used to filter out most of the carbon monoxide in the production gas as Cheng Nuo expected, but the problem is that this method cannot remove all the carbon monoxide, and after this treatment, the hydrogen still contains a small amount of carbon monoxide.

Faced with this question, everyone in the chemical team fell into deep thought.

The whole conference room fell into a different kind of silence, except for the hands of the clock on the wall, which clicked.

Liang Qichao was originally an outsider, he was okay at first, and he could still be an atmosphere group or logistics group, but now he encountered an academic problem that he didn't understand, and the room was too quiet, so he couldn't sit still.

Coughing deliberately, Liang Qichao broke the silence: "What, Zhiyuan, I don't think everyone can think of a reason right now, I think it's better for us to discuss something else, change our brains, and help me come up with ideas." ”

"Oh? Ren Gong, please speak. Cheng Nuowen said.

"Actually, it's easy to say, Zhiyuan, didn't you ask me to contact Liu Xiang more, I did what you said at the beginning, and the contact between them can be regarded as harmony, otherwise we wouldn't have come to their office, but the current situation is a little unpredictable for me." Liang Qichao said slowly.

"Is it because of the scuffle in Sichuan? It is estimated that it will not be able to calm down in a short time, but the scale will not be too large, and it will not affect us in a short time, if you are not at ease, you can also bet on the one named Liu Wenhui, speaking of which, Liu Xiang is also his own family, and he is still an uncle and nephew. Cheng Nuo hesitated for a moment and said slowly.

Speaking of which, Cheng Nuo has a habit of saying that it is good or bad, that is, he is too involved in doing things.

The good thing is that when he conducts scientific research, he can devote himself to it, forget everything, and use his time efficiently, which has the effect of doing more with less.

The bad thing is that when he is busy with one thing, he will instantly forget all the things around him and the outside world, it is easy to miss some things, and he is relatively slow to respond strategically.

"Yes, from the perspective of others, this Liu Xiang is indeed a talent, but the problem is that this person is too repetitive, I am afraid that we will invest too much in him, and in the future, the gains will outweigh the losses, and this kind of politician I hate most in my life." Liang Qichao's tone was a little hurried.

Cheng Nuo shook his head with a smile and said meaningfully: "Isn't going back on your word a necessary skill for politicians?" ”

"This ......" Liang Qichao was speechless for a while, he didn't want to admit it, but thinking of his past on the mountain, he had to nod: "That's true." ”

In fact, it's no wonder that Liang Qichao looks like this, it's just that the "Protectorate War" in Sichuan is too funny.

At the beginning of the Yasukuni Campaign, Liu Xiang was a brigade commander in the First Division of the Old Sichuan Army.

The 1st Division stood on Liu Cunhou's side and blocked the westward advance of the Yasukuni Army.

In Sichuan's Neijiang monk's field, Yisidui, Pimu Town, Dongjiezi, Baima Temple and other places, the troops led by Liu Xiang fought fierce battles with the Yunnan-Guizhou army.

When Liu Cunhou's army was defeated and retreated, and the Kuomintang Xiong Kewu and others took advantage of the victory to pursue them, the first and second divisions of the Jiuchuan Army immediately fell to Xiong Kewu's side and immediately sent a telegram in response to the protector.

A vigorous Yasukuni battle ended in this almost absurd way.

Liu Xiang behaved like a wall, no wonder Liang Qichao looked down on him.

But this is the kind of behavior, because Xu Xiaogang, the former commander of the First Division, felt shameless to face Xiong Xiaowu, so he sent a telegram after the war to resign and left, but Liu Xiang took this opportunity to climb up directly and was directly promoted from brigade commander to division commander.

Although the entire Sichuan Army was reorganized into seven divisions, only Liu Xiang's division had a long history, was well-trained, and relatively complete.

And at this time, Liu Xiang was more of a professional soldier, and he did not have the deceitful atmosphere of later politicians, which was relatively "simple".

But right now, the "Protectorate War" is not over yet, which means that this time has passed, and it is an excellent opportunity for Cheng Nuo and them to bet, and sending charcoal in the snow is more precious than icing on the cake.

Under Liang Qichao's gaze, Cheng Nuo hammered down: "We not only have to bet, but also add chips, so let's go back and contact Liu Xiang, saying that we are willing to integrate the local chemical plant and establish a complete supporting industrial park to form a small internal circulation industrial system."

One day, with the expansion of our industrial scale, this internal circulation will be expanded to the entire Sichuan, southwest, and even the entire land of China, which is promising.

During this period, we will generate high tax revenues to give back to the local area and support local development, whether it is building schools or hospitals, we can do our part. ”

After a slight pause, Cheng Nuo continued: "In my opinion, what we use most of Liu Xiang is his ambition, the heart to climb up and expand outward, after all, although our Academy of Sciences has come to Sichuan, our vision will not only focus on the local area. ”

After speaking, Liang Qichao thought so, and after asking a few more questions and getting the answer he wanted, he turned around and left, and set foot on the road to contact Liu Xiang again.

After Cheng Nuo's matter was resolved, the members of the research team over there found him again.

Fan Xudong smiled: "Zhiyuan, I know how to solve the problem of residual carbon monoxide." ”

Cheng Nuo couldn't help laughing: "Tell me, what results have you discussed?" ”

Fan Xudong pulled the moving blackboard over, quickly wiped the things on it, and introduced while calculating: "We all know that carbon monoxide is toxic and harmful, which not only affects the purity of our synthetic ammonia, but also harms the physical and mental health of the workers and masters, so after we discussed it,

It is believed that the remaining small amount of carbon monoxide should be further removed by a copper ion solution......",

"Wait." Before Fan Xudong could finish speaking, Cheng Nuo directly interrupted him: "Although the idea is good, don't forget that most of the devices we use are made of iron parts, and the copper ion solution has a corrosive effect on iron, so we can't produce a batch of chemical fertilizers, so let's replace a batch of equipment."

Not only is it more troublesome to install, but our production costs will remain high, and when it comes to the retail end of foreign goods, our prices are almost not competitive, and a little bit of a price war trend will face bankruptcy! ”

Fan Xudong thought about it carefully, it was really like this, and his face was a little gray: "Alas, it's all because I didn't think deeply enough, after discussing the answer just now, I couldn't wait to find you, but I didn't expect to forget about this stubble." ”

Cheng Nuo waved his hand generously: "I don't think it's anything, no matter what, you have all discussed a result." Let me think...... Although copper ion solutions are somewhat corrosive, they are not completely insurmountable. ”

Frowning and thinking for a moment, Cheng Nuo made up his mind and said: "In this way, we have no other way out at the moment, let's start with the copper ion solution and see how to solve the corrosion problem." ”

Fan Xudong nodded: "It's okay, then do as you say, and I will arrange for the team members to tackle technical problems." ”

After saying this, Fan Xudong was about to leave, but before he could turn around, he was stopped by Cheng Nuo.

"Collective action is too slow, so let's do it, you divide the team members into pieces, each group is responsible for a direction, and regularly organize and report the results, and when one group makes progress, the other groups immediately follow suit, maximizing our efficiency."

Fan Xudong said with a smile: "This is better, I believe that in less than half a month, we can solve this problem." ”

As expected, it even exceeded expectations.

It took less than a week for the instrument corrosiveness problem to be resolved.

Only a certain amount of ammonia needs to be added to the copper ion solution used to remove carbon monoxide to solve the problem of iron corrosion.

At this point, the process for producing high-purity hydrogen in large quantities has finally been developed.

In this way, new problems keep emerging and being solved.

After the development of cheap and efficient catalysts and the mass production of high-purity raw gases have been solved, how to design and manufacture a large-scale synthetic reaction device that can withstand high temperature and high pressure has become a top priority in front of Cheng Nuo.

Although the experimental device previously developed by Cheng Nuo can provide a lot of reference for the development of the pilot reaction device, the pilot reaction device is obviously not feasible to simply enlarge the laboratory device.

When developing a pilot reaction unit, the first problem encountered was that of a large air compressor.

Although Chongqing had some sizable factories, the largest air compressor at the time was used to transport air to the mines. The maximum pressure of this compressor simply does not meet the requirements of the ammonia reactor.

As for Air Liquide's compressors, although they can be scaled, they cannot continue to operate at high temperatures because their joints are made of copper, and the melting point of copper is too low, only 1083.4 degrees Celsius.

and the compressor for refrigeration is not tightly sealed, which is easy to leak.

Therefore, Cheng Nuo had no choice but to use the dead horse as a live horse doctor, and called Tesla, who was studying radio, to redesign the air compressor according to the needs of synthetic ammonia production.

And this redesign drama is not over, because the working environment of the ammonia reactor is very harsh.

The internal pressure is usually 20 times that of a steam boiler, the temperature is so high that the iron can be reded, and in this case, it is also necessary to ensure that the continuous input of nitrogen and hydrogen in a certain proportion does not leak, and the resulting ammonia can be easily pumped to the separator.

Therefore, Cheng Nuo had to design and manufacture a number of special monitoring instruments and meters.

In fact, when he came here in the middle, Cheng Nuo also felt a little tired, although he knew that the chemical industry was poor and white, and everything needed to start from scratch.

But he never expected that there was no "knife" to open the way in China.

Careful calculations show that the first scientific instrument company in China could not be established in Shanghai until 1925, and before that, both teaching and scientific research instruments had to be purchased from foreign countries.

This is also the reason why Huasheng Electric Appliance Manufacturing Factory can cause a social sensation after the ammeter was manufactured.

Without him, only Watson could have made domestic products at that time.

Looking at this bigger and bigger stall, Rao is Jiang Jiangzuo, a layman, couldn't help but be a little depressed: "Zhiyuan, I remember that although our chemical problems continue to appear, they are also constantly being solved, how can the more they are solved, there are more and more problems?" ”

Cheng Nuo smiled bitterly: "Because every step we take is a field that Chinese people have never set foot in, and they have never seen the scenery." ”

Jiang Jiangzuo was in a slightly better mood: "Also, with us people opening the way, it will be relatively easy for latecomers to move forward, but it will be difficult for us." ”

Cheng Nuo nodded: "Speaking of which, in order to install these instruments, a number of special joints and valves have to be developed." In addition to this, how do you heat the synthesis reaction vessel? How do you maintain the pressure inside the synthesis vessel? What materials are used to make it? These problems need to be solved one by one.

However, we are not studying these things in vain, we have been writing a research log in the middle, and we can sort out the correct research results and use them for other purposes in the future. Wrong ones also have their merits, so collect them for everyone's reference, so as not to fall down twice on the same pit. ”

If there is a will, it will be done, and the one hundred and two Qin passes will eventually belong to Chu.

Hard-working people, the sky is not bearable, lying on the salary to taste the gall, three thousand Yuejia can swallow Wu.

In the later research, especially in the process of developing synthetic reaction vessels, Cheng Nuo and his team not only studied the most advanced steam locomotives, gasoline engines and diesel engines at that time, but also visited local steel factories.

After a month of research, we found a factory with good steelmaking technology and finally designed and manufactured two cylindrical synthetic reaction vessels up to 2 m4 in height, and placed them in protective covers made of reinforced concrete.

Of course, high-quality concrete still has to buy foreign goods.

It's a pity that the synthetic reaction vessel exploded after only three days of operation, and Cheng Nuo was puzzled, thinking that the steelmaking technology was not good, and the embrittlement of the inner wall of the reaction vessel made of carbon steel led to the explosion.

Later, after several demonstrations, it was found that the hydrogen atoms with a small particle size drilled into the carbon steel after thermal expansion under high pressure and reacted with the carbon elements in it.

No matter how good the steel is, it can't stop the reaction of hydrogen atoms.

In the middle, Cheng Nuo also wanted to apply a protective layer to prevent the two sides from reacting.

It can be argued that with the technology of the time, high-strength steel contains some carbon elements to a greater or lesser extent, and no matter what protective layer is applied to the inner wall, hydrogen atoms can easily penetrate it under the action of high pressure and drill into the interior of carbon steel, unless a layer of pure gold is coated on the inner wall, which is too costly.

After several twists and turns, three or four months passed.

Cheng Nuo knew that he couldn't go down like this anymore, and the broken jar was broken, so it was better to simply plug it than to sparse it, so he simply drilled some small holes in the carbon steel cylinder to directly discharge a small amount of hydrogen that penetrated into the outside of the inner lining.

I didn't expect it to work wonders.
