In view of the sulfur recovery and control of high concentration H2S acid gas from chemical industries, combined with the existing problems in research of H2S selective oxidation, the direct technology of H2S selective oxidation and catalytic materials of middle-high temperature is proposed. The catalytic materials used in the range of middle- high temperatures are rationally synthesized with different structure and functions, the selective oxidation of H2S and Claus reaction process were systematically studied on them. The related side reactions, by-products, the reaction mechanism, coupling reaction mechanism and multi-component kinetics are comprehensively studied and explored. It aims to obtain good H2S selective oxidation materials and bifunctional catalytic materials for Claus reaction, to clarify the catalytic reaction mechanism and multicomponent kinetics, to develop a direct selective oxidation and coupling technology for H2S in the medium and high temperatures ranges. And expand the application scope of H2S selective oxidation technology, realize standard emission and sulfur resource recovery, provide scientific and technical support for reduction and control of acid gas emission and resource recovery in chemical industrials.
