[Abstract]:The direct decomposition of hydrogen sulfide to produce hydrogen and sulfur can not only effectively control the hydrogen sulfide produced in the production process of petroleum, natural gas, coal and mineral processing, but also solve the problem of environmental pollution. It can also get clean energy hydrogen energy while recovering sulfur. In this paper, the direct decomposition (direct thermal decomposition, catalytic thermal decomposition, superadiabatic decomposition), electrochemical decomposition, photocatalytic decomposition and plasma decomposition of hydrogen sulfide to produce hydrogen and sulfur are reviewed. The thermodynamic basis is briefly introduced, and the current research situation of various technologies at home and abroad is described in detail. The research methods, technical characteristics, reaction properties, advantages and disadvantages, as well as the possible breakthrough points in the future research of these technologies are analyzed in depth. Finally, the development trend of hydrogen sulfide direct decomposition technology is prospected. It is pointed out that the combination of membrane technology, catalytic technology and plasma technology will be the future development trend of hydrogen sulfide decomposition technology.
