Source of hydrogen for synthetic ammonia production
Thread Content
I would like to ask everyone: what is the source of raw hydrogen in the current ammonia synthesis process? Is it feasible to use coal-based hydrogen production technology for ammonia synthesis processes with a capacity of less than 100,000 tons per year?

No, I just wanted to ask about things in this area. Currently, the gasifiers used for coal-to-hydrogen production all have a capacity of over 1,000 t/d, which means that the production of hydrogen generates a demand for raw hydrogen.
It’s okay to ask; it’ll liven things up a bit! It is recommended that those upstairs browse the forum more often; you can find information related to you there!
It is generally H2 that has been produced through gasification and then purified via shift reaction
Both coal and natural gas can be converted into hydrogen!
100,000 tons of ammonia – using industrial waste gas or biomass gasification for drying is not feasible due to the small scale.
It is due to scale considerations; if gasification is used, the gas produced by a 1,000 t/d furnace will not be fully utilized. Are there any industrial facilities that can serve as a model for industrial waste gas or biomass gasification?
There are emissions from calcium carbide furnaces, coke ovens, and blue carbon furnaces. In the Northeast, there is a company named Huaben that uses biomass gasification; I’m not very familiar with other methods. Perhaps it’s simpler to use biomass power generation for grid supply in nearby areas, as gasification requires oxygen or oxygen-enriched air, which makes the process more complicated and longer.
Okay, I got it. Thank you! ~~~~~~~~~~~~~~~~~~~~
If funds permit, considering a small space furnace is an option; the 120,000-ton space furnace in Changshan is already in operation. The Ende furnace can also be considered, though it has higher energy consumption. The choice mainly depends on the local coal quality – both space furnaces and Ende furnaces are suitable for low-quality coal
