Zinc oxide desulfurization
Thread Content
I happened to notice that in the zinc oxide desulfurization reactor, not only does a chemical absorption reaction occur between zinc oxide and inorganic hydrogen sulfide, but certain organic sulfur compounds also undergo transformation reactions under the catalysis of zinc oxide and zinc sulfide, resulting in the formation of hydrogen sulfide and olefins. Does this organic sulfur refer to thiol?
Yes, please refer to Illustrated Process Diagrams in Chemical Production (3rd edition), P43
Our natural gas is this, along with iron oxide desulfurization
Good question; transformation does occur, but I also want to know the specific objects involved!

I remember it’s the conversion of organic sulfur to inorganic sulfur, right? That happens in the hydrogenation reactor when olefins are saturated ? Is the ZnO reactor only used to absorb H2S? In natural gas, the organic sulfur is generally ethanethiol; there are also other types of thioethers and sulfonic acids as well

It mainly depends on the reaction efficiency of the hydrogenation reactor. Also, analyze the raw material composition. Check whether there are thiols, thioethers, or other compounds in the raw materials that are difficult to hydrogenate, or consider whether the reaction temperature is too low. The main areas to analyze for reasons lie in the catalyst, raw material pretreatment, and the composition of the raw materials.
