Abstract

The invention discloses a composite carrier comprising three components of activated carbon, sepiolite and titanium oxide. PEG-2000 is used as a pore-enlarging agent for the composite catalyst. Pore ​​structure and high specific surface area support material.

Description

technical field [0001] The invention relates to a preparation method of titanium oxide-sepiolite-activated carbon composite carrier. Background technique [0002] Supported catalyst is a conventional catalyst structure type in the prior art. Activated carbon is used as a catalyst carrier material because of its high specific surface area. The catalytically active components are supported on the surface of activated carbon by impregnation and other loading methods to form a supported catalyst. . Due to its special structure, sepiolite exhibits excellent adsorption, rheological and catalytic properties, and has received increasing attention from researchers in many fields, especially in the field of catalysis. Titanium dioxide has been developed as a catalyst carrier in recent years, and commonly used titanium dioxide carrier types such as P-25. [0003] In the prior art, activated carbon, sepiolite or titanium dioxide are mostly used alone as catalyst supports. So far, ther...
