| abstract |
The invention discloses a low-temperature carbonyl sulfide hydrolysis catalyst and a preparation method and application thereof. Alumina hollow spheres modified by an activated carbon pore-forming agent are used as carriers, holmium oxide and samarium oxide are used as catalytic active components, and zirconium, cerium, and rubidium are compositely oxidized. material as a catalyst. Based on the quality of the carrier, the mass percentage of the active components is 1% to 5%, and the mass percentage of the co-catalyst is 0.05% to 0.5%. The catalyst carrier is added into the polytetrafluoroethylene hydrothermal reaction kettle, and is prepared by hydrothermal, drying and roasting. The catalyst has low applicable temperature and high conversion efficiency. The conversion efficiency of carbonyl sulfide is greater than 90% at 90-180°C. The product can be widely used in steel, petrochemical and other fields. |
