Preprocessing equipment for antimony pentachloride waste catalyst and processing method thereof

Abstract

The invention discloses preprocessing equipment for an antimony pentachloride waste catalyst and a processing method thereof. The technical problem that the processing on the antimony pentachloride waste catalyst is lacked in the prior art is mainly solved. The preprocessing equipment for the antimony pentachloride waste catalyst disclosed by the invention comprises a reactor, wherein the reactoris connected with a rectifying tower; the rectifying tower is connected with a catalyst processing tank; the catalyst processing tank is connected with a gas-liquid separation tank; the gas-liquid separation tank is connected with a washing unit; the washing unit is connected with an alkali washing unit; the alkali washing unit is connected with a burning device. According to the preprocessing equipment disclosed by the invention, the problem is solved preferably, and the preprocessing equipment can be used for preprocessing the antimony pentachloride waste catalyst.

Description

technical field [0001] The invention relates to a pretreatment device and a treatment method for spent antimony pentachloride catalysts. Background technique [0002] In the production process of HFC-245fa, the process that can be used is the liquid-phase catalyst fluorination method. If antimony pentachloride is used as the catalyst, the catalyst will become a waste catalyst due to deactivation. Its composition is complex, mainly containing halogenated hydrocarbons, fluorinated hydrocarbons, Hydrogen fluoride, hydrogen chloride, etc. have a great impact on the environment and are hazardous wastes that must be properly disposed of or comprehensively utilized. At present, there are many methods and professional companies that can recycle waste catalysts of antimony pentachloride. However, the spent antimony pentachloride catalyst contains hydrogen fluoride and organic matter, among which hydrogen fluoride is very corrosive, and the organic matter needs to be incinerated and ...
