Problems solved by technology

However, due to the pollution and corrosion of waste lye, the alkaline washing method is not an ideal demercaptan method.
Other methods for removing mercaptans are mainly catalytic oxidation, that is, under certain catalytic conditions, mercaptans are removed through oxidation reactions. The specific processes include liquid-liquid method, liquid-solid method, and activated carbon-supported cobalt phthalocyanine as catalyst No caustic alkali fixed bed method, the improved fixed bed method (CN1067709C) of activated carbon fiber carrying cobalt, copper or zinc salt, the main disadvantages of these techniques are that on the one hand, strong alkali or relatively expensive materials need to be used as catalysts; Oxygen or air is used as the oxidant, the cost is higher and the process is more complicated

Abstract

The present invention relates to a polymer material with action of removing thioalcohol. It can be used for removing thioalcohol in gas or liquid organic material. It is characterized by that said polymer material contains positive dibasic copper ions, said copper ions can be connected on the polymer skeleton by means of chelation group.

Description

technical field [0001] The invention relates to a composition, in particular to a polymer material with mercaptan removal, which can be used for removing mercaptans in gas or liquid organic matter. Background technique [0002] Mercaptans have a foul smell, and as long as there are very few low-carbon mercaptans in the gas or liquid organic matter, it will have an unpleasant smell. Mercaptans are organic compounds with high activity. The presence of mercaptans will seriously affect the performance of organic chemical products, reduce the stability and storage resistance of gasoline and diesel, etc., corrode metals, and shorten the service life of equipment. Mercaptan removal is not only a requirement to ensure product quality, but also one of the effective measures to protect the environment and improve air quality. And many industries such as thermoelectricity are also important. [0003] The traditional method of removing mercaptans is alkali washing, that is, to fully c...
