Iron-containing pseudoboehmite, sulfur recovery catalyst protected against oxygen leakage, and method of preparation

Abstract

The application discloses a kind of iron-containing pseudo-boehmite, anti-leakage oxygen protective sulfur recovery catalyst and preparation method, in the preparation method for preparing pseudo-boehmite using hydrothermal method, iron-containing compound, amphiphilic surfactant and organic solvent are added;During hydrothermal reaction, the amine group of the head of amphiphilic surfactant and the alkyl of tail are located in aqueous phase and oil phase respectively, the hydroxyl on the surface of pseudo-boehmite crystal nucleus and the amine group of the head of surfactant condensation reaction occurs, and oil-in-water Pickering emulsion reaction system is formed, and iron-containing pseudo-boehmite is finally prepared by reaction.The iron-containing pseudo-boehmite is formed and used as anti-leakage oxygen protective sulfur recovery catalyst, to avoid the problems of existing impregnation method for preparing iron-containing catalyst, such as a large amount of waste water and waste liquid generated in production process, and low iron utilization rate of catalyst.
