Method for reinforcing oleophobic property of catalyst surface

Abstract

The invention discloses an oleophobic property reinforcing method of catalyst surface, which comprises the following steps: coating certain acid catalyst with oleophobic property such as Teflonx-{[(HSiW) / (SiO2)]y)(1-x), Teflonx / Amberlyst-15 and Teflonx / Amberlyst-35; detecting the finishing and finished touch corner of solid acid surface and soybean oil drip through droplet shape analyzer.

Description

Technical field:

[0001] The invention belongs to a method for enhancing the oleophobicity of the catalyst surface, in particular to a preparation method for enhancing the oleophobicity of the catalyst surface by using polytetrafluoroethylene. Background technique:

[0002] Adsorption is of great significance to the catalytic process and catalytic research. Adsorption is the prerequisite for catalytic reactions. Usually, the heterogeneous catalytic process of solid catalysts is divided into five stages: 1) The reactant diffuses to the catalyst surface; 2) The reactant diffuses on the catalyst surface. Adsorption on the surface, so that the reactant molecules are in an activated adsorption state; 3) The molecules in the activated adsorption state react and become products (at this time, the product in the adsorbed state); 4) The product is desorbed; 5) The product after desorption Diffusion into outer space. The wettability of solid surfaces is a characteristic property of ma...
