Standing in front of the stall was a middle-aged man with a gentle appearance, his body was neatly cleaned and clean, cleaner than most people in the gathering place, wearing glasses, his collar and cuffs were severely worn, his sleeves and elbows, and the hem of his suit were patched with two patches, and he was dressed in the gathering place quite well, and his face was not like other poor people without any flesh, obviously, this person's identity was a civilian who could receive relief.

He carefully looked at the look on Zhang Xiaoqiang's face, and when he first saw Zhang Xiaoqiang stop beside him, he was slightly happy, and then he saw Zhang Xiaoqiang frowning at the names of those books, his heart was half cold, and his mouth trembled and wanted to say something, but in the end he still lowered his head, and he didn't have the courage to speak when he came to his mouth.

"What are you doing? What is it for? After pondering for a long time, Zhang Xiaoqiang finally admitted that he was not the material, and he couldn't figure out the meaning on the cover.

The man glanced at Zhang Xiaoqiang carefully, and saw Zhang Xiaoqiang looking at the cover in a daze, as if he really didn't understand, and the disappointment in his heart was indescribable, but he didn't show impatience and explained to Zhang Xiaoqiang carefully.

"These are some books related to the indirect liquefaction of coal, explaining the theoretical knowledge of converting coal into oil・・・・・・

"Wait, you're saying that these things can turn coal into oil?"

Zhang Xiaoqiang was shocked, in his mind, oil is a very deep thing, without drilling rigs, no refining equipment, no series of purification processes, he absolutely can't turn oil into diesel gasoline.

"No, no, no, this refers to the relevant theoretical knowledge, coal indirect liquefaction is to first react coal with oxygen and water vapor at high temperatures, so that all coal is gasified and converted into syngas, that is, a mixture of carbon monoxide and hydrogen, and then synthesized into liquid fuel under the action of a catalyst・・・・・・"

The man said a lot of things, Zhang Xiaoqiang didn't understand it, at least he understood one thing, converting coal into refined oil used in his vehicles requires a very troublesome process, and a lot of equipment and site personnel, among which there are many related professionals, and it seems that it is impossible to gather in a gathering place where everything is lacking.

"Alas, I said, your thing is too troublesome, I thought that if you get a stove and make a pot with a steel pipe, you can produce oil, and there is no market for your thing in the gathering place!"

Zhang Xiaoqiang said it casually, but he was making up his mind in his heart to take this man under his banner, it seems that this guy is the legendary high-tech talent?

When the man heard Zhang Xiaoqiang's casual words, the whole person seemed to be pulled out of his backbone, and he hit the ground with his butt, and said loudly:

"I also know that my life's work has been on this, and when I said that I wanted to escape, the first thing I thought of was to bring books and materials, and when I got to this step, I didn't think ・・・・・"

Hearing what the man said so bleakly, Zhang Xiaoqiang was also very embarrassed, he was aroused by the man, and missed the hundreds of g love action movies hidden in the computer at home, which was his ten years of hard work, and he selected the best of the best, and there were more of the best goods that were out of print for nearly half a long time and can no longer be found on the market.

"I also know that you said that the stove is oiled in the pot, and the local oil refining that used to make a lot of noise is, that thing does not use coal, just scrapped rubber tires, I remember that tons of waste tires can be "refined" tons of oil, and at the same time, there are by-products, nearly tons of steel wire ・・・・・・・"

Zhang Xiaoqiang has heard of soil oil refining, any gutter oil, all of them. He hadn't heard of refining oil from scrapped tires, and he couldn't think of what kind of oil could be made from scrapped tires, could it be lubricating oil?

"Tell me what's going on with the soil method of oil refining, and I'll buy all your books."

Zhang Xiaoqiang is full of interest, it seems that in the last days, there are more scrapped vehicles and waste tires, as long as they can use the oil they practice, it is also an industry, isn't it?

"Uh...・・・・ I personally recommend not to use tires to refine oil, that thing is quite polluting to the environment, and the refining process will produce exhaust gas, wastewater, and residues, all of which are highly toxic substances, harmful gases cause serious pollution to the atmosphere, waste water and waste gas will cause devastating damage to the soil and water sources, and there is no grass around the oil refining workshop, and trees have died・・・・・・"

The man seems to be very conservative, has a deep dislike for this kind of thing, and when his stomach is still rumbling, he actually teaches Zhang Xiaoqiang a lesson.

"Don't tell me about those terms and conditions, what's the world? The living are going to die, love the environment? Do you help zombies take care of the environment? Hurry up, or I won't buy your book・・・・・・"

Zhang Xiaoqiang is very annoyed by this kind of person, he can't figure out the actual situation and go online, under the absolute suppression of survival, everything that has nothing to do has to make way for survival.

"Fuel oil can be refined, for example, diesel・・・・・"

"Wait, you say it again!" Zhang Xiaoqiang was afraid that he didn't hear clearly, so he asked repeatedly.

"What I'm talking about is that the oil refined from rubber tires is mainly fuel oil, which can be directly refined into diesel."

"Don't talk about anything else, let me ask you, tell me honestly, do you know how to refine oil? It's soil oil refining! ”

Zhang Xiaoqiang is a little nervous, but also a little excited, the bulk of the fuel consumption in the fleet is diesel, military vehicles, transport trucks, and diesel generators, up to now, the fleet's diesel reserves have been used up one-third, this is still a small fleet, in the base, the demand for diesel can be said to be endless, two-thirds of the diesel generators because there is no diesel can only be used as decoration, and the base's demand for electricity is quite terrifying.

The man was obviously stunned when he heard Zhang Xiaoqiang's questioning, he looked at Zhang Xiaoqiang seriously, and when he saw Zhang Xiaoqiang looking at him with a serious face, his heart moved, and after a while, he nodded hesitantly, and then he said:

"It is very easy to practice diesel, the equipment should be professional, and the materials of the refining equipment should also be better, otherwise it is easy to poison the operator with exhaust gas leakage, and the quality of the refined oil is not very good, which will cause the oil nozzle to be blocked, the engine will be damaged, and it may seriously lead to an explosion ・・・・・"

Zhang Xiaoqiang nodded thoughtfully, and was a little disapproving, compared with the upcoming benefits, which problems are small problems, but when he heard that it would explode, his heart was a little empty, and the explosion would cause casualties, because the inferior oil seemed to be a little bit unacceptable?

"Do you have a way to purify low-quality diesel? Purification to a large extent, don't be afraid of consumption, I don't need to sell it for money, I just need to be able to ensure its safety and not cause explosion・・・・・"

When the man heard this, he was sure that Zhang Xiaoqiang had plans to contain him. Although I don't know Zhang Xiaoqiang's background, judging from Zhang Xiaoqiang's clothes and equipment, the man in front of him may really be a little capable. The thought that he might get a job with enough to eat warmed the man's heart.
