H2 content in the hydrogen production feed gas
Thread Content
I would like to ask: When using coking dry gas as the feed gas for hydrogen production, the analysis results show that the H2 content in the desulfurized coking dry gas (feed gas for hydrogen production) is around 20%! Is the H2 content in the hydrogen production feed gas also at this level among your colleagues? Can the proportion of thermal cracking dehydrogenation reactions reach this value? I have doubts about the test results and hope an expert can give some guidance!
Why isn’t anyone answering? I’ve just started working here and don’t know much about it yet. Please wait a bit longer, original poster – experts will surely respond
I. The hydrogen content in coking dry gas is primarily influenced by the following factors: 1. The properties of the residue oil. 2. Thermal pyrolysis reaction temperature. 3. Whether other dry gas components are mixed in the coking dry gas. 4. Testing methods. II. Our coking dry gas has a hydrogen content ranging from 11% to 16%.

By desulfurization as mentioned by the poster, does it refer to ethanolamine desulfurization or zinc oxide desulfurization for hydrogen production?
The hydrogen content in the coking dry gas after desulfurization using ethanolamine can reach 40%, mainly due to the presence of a large amount of light gases; this meets the requirements for hydrogenation, and testing generally yields accurate results.
The results should be correct; we use a portion of the gas that has been aromatized here, with an H2 content of around 60%, and it contains no olefins. It’s just that the amount isn’t enough, so catalytic dry gas still needs to be mixed in.
The H2 content in our coking dry gas is around 10%.
The H2 content here is always above 20%, as the hydrogenation reaction requires H2, and the H2/lean hydrocarbon ratio should be greater than 3. The lean hydrocarbon content in typical coking dry gas is around 5-7%, so the H2 content is kept at 20% as a conservative value.

The hydrogen content in the coking dry gas here is 17-18%
Here, the hydrogen content in the coking dry gas is 13–16%, while the hydrogen content in the catalytic dry gas is around 22%
