High-purity desulfurizing agent for hydrogen production equipment
Thread Content
Experts, what are the main components of advanced desulfurization agents used in hydrogen production facilities, and under what circumstances are such agents employed? What are the operating conditions for precision desulfurization agents? Could you provide a detailed explanation?
For hydrogen production units that use natural gas, naphtha, etc. as raw materials (except for methanol-based hydrogen production units), it is necessary to thoroughly remove sulfur from the raw materials, ensuring that the sulfur content in the gas fed into the reaction is below 0.2 ppm, in order to reduce the negative impact of sulfur on the activity of the conversion catalysts. The absorption equilibrium constant of zinc oxide for hydrogen sulfide remains high at 200–500°C. Given the properties of zinc oxide desulfurization agents, zinc oxide is generally chosen as the desulfurizer for advanced desulfurization.
What about the desulfurization of carbon 3-carbon 6 hydrocarbons?
There seems to be a copper-based desulfurizer similar to the low-temperature catalyst as well
There are high-precision desulfurization methods based on copper and zinc.

I work in the field of desulfurization agents; zinc oxide is the cheapest option, along with copper/nickel-based agents. There are differences in desulfurization efficiency, especially when it comes to the removal of organic sulfur; ordinary H2S is relatively easier to handle. Those interested can discuss this in more detail
