Sulfiding mechanisms are explained using temperature programmed sulfiding profiles of MoO./Al.O., WO./A1.O., reduced and oxidic Ni/Al.O., several supported and unsupported manganese oxides, and MnAl.O.. Also the regeneration of MnAl.O. and MnO with steam is d

Much of the desulflirization research and development effort has used zinc-based sorbents, which are quite reactive at the temperatures and pressures of interest, have acceptable sulfur capacities, and are capable of reducing H.S concentrations to less than 20 ppmv.

Calcium-based sorbents are the prime candidates for in-bed capture of sulfur..The removal of sulfur takes place through the reaction of hydrogen sulfide with calcium-based sorbent and produces calcium sulfide, which is not stable and there

A single or a mixture of metal oxides can be dispersed on the surface and in the pores of the support material. Thus, it may be possible to improve dispersion of active metal oxides in the solid matrix, to increase the surface area for the reaction, and to impart stru

Regeneration of Sulfided Sorbents and Direct Production of Elemental Sulfur, The standard method of sorbent regeneration, which involves the oxidation of metal sulfide to metal oxide and SO., creates several problems. The reaction is highly exothermic and temperature excursions can cause the porous, high surface area sorbent to sinter. Addition of a diluent to the regenerat
