1results about How to "Reduce hydrolysis rate" patented technology

The application provides a titanium dioxide type low-temperature hydrogenolysis catalyst and a preparation method and application thereof. The catalyst comprises a titanium dioxide carrier and an active component loaded on the titanium dioxide carrier, and the active component comprises scandium oxide and tungsten oxide. The preparation method of the catalyst comprises the following steps: dipping the titanium dioxide carrier in a mixed solution of scandium salt and tungsten salt for a period of time, so that the scandium salt and the tungsten salt are loaded on the titanium dioxide carrier; and then drying and calcining the titanium dioxide carrier loaded with the scandium salt and the tungsten salt, to obtain the titanium dioxide type low-temperature hydrogenolysis catalyst. The catalyst has good sulfur dioxide hydrogenation activity and organic sulfur hydrolysis activity, and can be applied to a process for treating sulfur recovery tail gas at a low temperature of 210-220 DEG C.
