Hydrogen Production from Thermocatalytic Hydrogen Sulfide Decomposition

Abstract

Experimental data on hydrogen production from hydrogen sulfide decomposition over various solid catalysts at elevated temperatures are reviewed. Special attention is paid to the use of carbon fibrous materials, transition metal sulfides and hydride — forming alloys (e.g. intermetallic compounds of rare earth metals and transition metals). The possibilities given by surface modification by vacuum methods (electron beam evaporation and magnetron sputtering) are also considered. It is shown that new effective thermostable catalysts can be produced by deposition of metal, metal oxide and some other coatings on carbon fibers, alumina ceramics and other supports.
