Study on heterogeneous catalysts for catalytic wet oxidation

Abstract

Catalytic wet oxidation is a powerful method for the treatment of high concentration refractory organic wastewater. the support and catalyst components constitute heterogeneous catalysts, and the main catalyst, co-catalyst and co-catalyst components. The main catalyst and co-catalyst are the main influencing factors of the catalyst. The preparation methods of catalyst include precipitation method, impregnation method and impregnation precipitation method. The performance evaluation indexes of heterogeneous catalysts include the activity, stability, selectivity and anti-toxic stability, mechanical stability of the catalysts. according to the principle of chemical transfer, the heterogeneous catalytic reaction process consists of seven steps.
