ABSTRACT:
Continuous process for the selective removal of hydrogen sulfide from a mixture of hot coal gasification gases containing hydrogen sulfide by contacting such mixture in a reaction or desulfurizing zone at an elevated temperature with a nickel-containing material whereby the nickel reacts with the hydrogen sulfide to form solid compounds from which the nickel content can be regenerated by oxidation and recycled back to the reaction zone, thereby effectively removing hydrogen sulfide from the hot gas mixture.
