Abstract

The invention discloses an ion exchanging resin load-type heteropoly compound, which consists of a heteropoly compound and ion exchanging resin, wherein the percentage of the heteropoly compound to the ion exchanging resin capacity is 50 to 200 percent. The ion exchanging resin load-type hteropoly compound can be used as catalyst for desulfurizing oil. In specific application, the ion exchanging resin load-type heteropoly compound is used as the catalyst, hydrogen peroxide is used as oxidant, acetonitrile is used as extracting agent, the ion exchanging resin load-type heteropoly compound, the hydrogen peroxide and the acetonitrile are placed into the oil to be desulfurized to be blended in thermostatic waterbath and reacted for 2 to 4 hours, the mixed liquid stands to be layered, and the upper layer is the desulfurized clean oil. The catalyst preparation process is safe, simple, non-toxic, harmless and pollution-free, the catalyst can be recyclable, and the defect that the heteropoly compound used as the catalyst is difficult to recycle can be overcome; and compared with the traditional process, the desulphurization process is simple, strong in desulphurization capacity, high in economic benefit and easy in industrialized production.

Description

technical field [0001] The invention relates to an ion-exchange resin-loaded heteropoly compound, a preparation method thereof, and its application as a catalyst in oil product desulfurization, belonging to the technical field of oil product deep processing in the petrochemical industry. Background technique [0002] With the rapid development of the automobile industry, the pollution of automobile exhaust to the environment is becoming more and more serious. The combustion of sulfur-containing compounds in gasoline produces SOx, which is not only the main source of acid rain, but also significantly reduces the conversion efficiency of automobile exhaust catalysts to NOx, incompletely burned hydrocarbons and particulate matter, and aggravates environmental pollution. Therefore, how to reduce the content of sulfur compounds in oil as much as possible has aroused widespread attention at home and abroad. [0003] The current oil desulfurization methods mainly include hydrodesu...
