Z-Sorb sorbent is a regenerable sorbent for hydrogen sulfide. It is based on zinc oxide supported in a porous matrix and contains a nickel oxide promoter. Originally, it was developed for tail-gas cleanup, but recently it has been tested for removal of hydrogen sulfide from hot simulated fuel gas that is representative of a coal gasification process. For the latter technology, previous fixed-bed sorbents have shown poor mechanical stability due to spalling when absorbing hydrogen sulfide in reducing gas atmospheres or when being regenerated over many cycles. Recent rests have shown that Z-Sorb sorbent had excellent chemical reactivity and mechanical stability for application in fixed-bed reactors. In an ongoing sorbent research and development program, PPCO has developed a fluidized version of the Z-Sorb III sorbent that is the subject of investigation in this paper.
