High-concentration hydrogen sulfide removal device with low consumption of absorbent and increased contact efficiency during the synthesis gasification process of petroleum coke for hydrogen production

摘要

The present invention provides a gas containing carbon monoxide generated through gasification of petroleum coke and a reaction gas containing steam, and reacts with a high-temperature catalyst and/or low-temperature catalyst to produce a synthesis gas converted into hydrogen. ) Petroleum coke for hydrogen production using an iron chelate aqueous solution that can be directly recovered as sulfur (S) by removing high-concentration hydrogen sulfide (H2S) in the syngas by bringing the iron chelate and syngas into co-current contact with an aqueous solution. It relates to a high-concentration hydrogen sulfide removal device with a low consumption of absorbent and increased contact efficiency during the synthesis gasification process. Because high-concentration hydrogen sulfide is removed from synthesis gas and regeneration is possible through simple bubble fluidization with oxygen or air, the process system is simple and operational It is easy to install and has the effect of reducing installation and maintenance costs.
