Biogas: I'm a ghost in the swamp, I'm the devil in the city's sewers, if you want to use me, beware of being eaten by me!

Methane, carbon dioxide, nitrogen, oxygen, hydrogen, carbon monoxide, hydrogen sulfide, VX poison, sarin poison, heding red, tabun (GA), ephedrine, opioids, mustard gas, nitric oxide, sulfur dioxide, chlorine, AIDS

Mustard gas: Wow, the biogas seniors are on Moments!

VX Poison: Biogas Predecessors Haunt!

Sarin Poison Gas: The Predecessor of Biogas is mighty!

Biogas: I'm a big family.

Methane: I am a member of the biogas family, and it is the most abundant in the biogas family.

Carbon dioxide: I'm also a member of biogas.

Nitrogen: +1

Oxygen: +1

Hydrogen: +1

Carbon monoxide: +1

Hydrogen sulfide: +1

Mustard gas restores hydrogen sulfide: The hydrogen sulfide brothers are also from the biogas family, wow, your "electric shock-like" sudden death is terrible!

Hydrogen sulfide restores mustard gas: I have very little in the biogas family, and only in high concentrations can humans have an "electric shock" sudden death.

VX Poison: Biogas can explode and be infinitely powerful.

Biogas reverts to VX poison: it's a credit to methane in my family.

Methane restores VX poison: I can account for 6 to 7 percent of the biogas, and it will explode under the right conditions, but I am harmless to humans at low concentrations, and people will suffocate to death at high concentrations.

AIDS: Biogas is so complicated, and each member of the family has different functions.

Mustard gas: How does our circle mix a microorganism?

VX Poison Replies to Mustard Gas: It was dangling in our poison circle before AIDS, it was a friend of opioids and ephedrine, it was a guy who loved to join in the fun, and liked it everywhere.

Mustard gas: I want to read the autobiography of the biogas predecessors!

VX Poison: Ask for an Autobiography!

Biogas: Here's my autobiography.

I, biogas, a mixture of gases.

I've been on this planet for a long time, and I've been living with all kinds of microbes for a long time.

What's more, some members of my family appeared before the emergence of microbes on Earth.

Biogas is the name given to me by humans.

As the name suggests, I am the gas that humans found in swampy wetlands.

A long time ago, humans discovered that swamps, sewage ditches, and manure tanks often bubble up during the hot season.

If an open flame is encountered, these gases will ignite.

Humans call this combustible gas produced in nature biogas.

In fact, I am a mixture of gases produced by the fermentation of various organic substances under anaerobic conditions by microorganisms.

My composition is complex.

Depending on the organics, fermentation microorganisms, and environmental conditions, my composition will vary.

In general, my main ingredients are methane and carbon dioxide.

Methane accounts for six to seventy percent and carbon dioxide for three to forty percent.

There are also small amounts of hydrogen, oxygen, nitrogen, carbon monoxide, hydrogen sulfide, and ammonia.

My family has methane that burns, so I'm a flammable gas, similar to natural gas buried in the ground.

After discovering me, humans used my fermentation generation principle to build a biogas digester to produce a large amount of biogas and use it as an energy source.

I am a secondary energy source, and it is a renewable energy source, in short, there are many benefits.

However, I am dangerous to humanity.

I can burn, and I can explode.

We have a complex composition, high concentrations of methane can suffocate people, and low concentrations of hydrogen sulfide can cause "lightning" death.

I'm a ghost in the swamp, I'm the devil in the sewers of the city, if you want to use me, beware of being eaten by me!

I make humanity love and hate at the same time.

AIDS: Wow, there's so much going on in a gas ball.

Ozone Returns AIDS: What's Wrong with Gas? I'm also a gas, I can kill microbes!

AIDS reverts to ozone: strong oxidants, I can't afford to provoke them, so I slipped away......
