Abstract

The invention discloses a Pt / Ce-USY catalyst for oxidative degradation of chlorine-containing VOCs and a preparation method of the Pt / Ce-USY catalyst. According to the preparation method of the Pt / Ce-USY catalyst for oxidative degradation of chlorine-containing VOCs provided by the invention, tetraammineplatinum (II) dichloride, cerous chloride and an ultra-stable Y molecular sieve are used as rawmaterials, CeO2 is loaded by adopting a precipitation-deposition method and Pt is loaded by adopting an ion exchange method, and the contents of CeO2 and Pt in the catalyst are 3-20% and 0.1-0.45% respectively. The catalyst is simple in preparation process and low in cost, has good low-temperature catalytic oxidation activity and stability on chlorine-containing VOCs and non-chlorine-containing VOCs, and presents good application prospects.

Description

technical field

[0001] The invention relates to a preparation method of a low-temperature oxidation degradation catalyst for chlorine-containing VOCs, in particular to a Pt / Ce-USY catalyst for oxidation degradation of chlorine-containing VOCs and a preparation method thereof. Background technique

[0002] Chlorine-containing volatile organic compounds (CVOCs) are a class of compounds that are extremely harmful to the environment and human health. The common ones are dichloromethane (DCM), chloroform (CF), dichloroethane (DCE), trichloro Ethylene (TCE), carbon tetrachloride (CT), chlorobenzene (PhCl), etc., are widely used as organic solvents and semi-finished products in chemical production processes due to their good chemical stability. Catalytic combustion technology is one of the most important and effective methods for the purification of CVOCs pollutants, and the development of low-cost, high-performance catalysts is the key to the application of this technology. The c...
