Names for gas
Thread Content
:) There are many types of gas. As far as I know, the names given to certain types of gas include: gas produced using air as a gasifying agent is called air gas； Gas produced using oxygen-enriched air or a mixture of pure oxygen and water vapor as the gasifying agent is called mixed gas ； Gas produced in an intermittent manner by alternately feeding oxygen-enriched air or pure oxygen along with water vapor into the gasification furnace is called water gas ； After adjusting the nitrogen content in its gas composition to meet the requirements for raw gas used in ammonia production, this type of gas is called semi-water gas. Should the gas by-product produced in coke ovens be called coke oven gas? So, what are the names of the gas produced by pressurized gasification of water-coal slurry and pressurized gasification of dry coal powder, respectively?

I think it’s also called semi-water gas. :lol
I think it’s also called semi-water gas.
I don’t think it’s reasonable to simply refer to it all as semi-water gas; after all, the composition of the gas produced by the gasification of water-coal slurry differs significantly from that of the gas produced by the gasification of dry coal powder – the former contains more hydrogen and less carbon, while the latter contains less hydrogen and more carbon
This requires domestic coal chemical industry experts or professors specializing in coal chemistry at universities to define the names of various types of coal gases
It’s just a name; as long as it can be effectively applied in production, that’s enough
The raw gas, after purification, is called fresh syngas; I’m not sure if this is the correct term, but that’s how we usually refer to it
I think it should be called semi-water gas, because air is used as the vaporizing agent.
Liquefied gas used in daily life is sometimes also called gas. In short, calling CO gas is correct; after all, we can’t call hydrogen gas gas, right?
There is currently confusion regarding the naming of gas; mainly, the old names differ from the new ones, and standardization is needed. **The relevant authorities should take care of this issue!
The various original names were classified based on the name of the gasifying agent, which of course also indirectly indicated the differences in composition. The gases produced by pulverized coal gasification and water coal slurry gasification contain high levels of CO+H2; they are mainly used for the synthesis of substances such as methanol, and it is more appropriate to refer to them as syngas. As for the factory, it can also be called crude gas before the essence; in any case, it should be named in a way that is clear and easy to understand, depending on the specific circumstances.
The gas produced by coking ovens is known as coke oven gas; the unpurified version is called crude gas, while the purified version is called clean gas
