Problems solved by technology

The catalyst A provided by this patent can react the sulfide in the resin and the hydrogen sulfide produced by the reaction with the metal oxide in the nickel-based catalyst A with high metal capacity and low activity to form metal sulfide, which can achieve the purpose of catalyst desulfurization and sulfur storage. The patent does not mention whether the catalyst A can completely remove the sulfur in the resin, or it is only a high-sulfur capacity protective agent that partially adsorbs the sulfur in the resin on the catalyst. In addition, the catalyst can dechlorine the resin raw material. In addition to the ability is also not mentioned

Abstract

The invention discloses a C9 petroleum resin prehydrogenation catalyst. The C9 petroleum resin prehydrogenation catalyst, by weight, comprises 30-50% of an active component M1 of a laminar structure,20-40% of an additive component M2 and the balance a carrier according to 100 weight percentages, the component M1 comprises Ni, Mn, Al and Mo, the component M2 comprises Ca and Mn, and the carrier isamorphous form aluminum silicon. The invention further discloses a preparation and application of the catalyst. The catalyst is used for C9 petroleum resin prehydrogenation, has the functions of hydrogenation adsorption desulfurization and dechlorination, and can effectively avoid sulfur and chlorine poisoning of a main hydrogenation catalyst at a late stage.

Description

technical field [0001] The invention relates to a catalyst for prehydrogenation of C9 petroleum resin, and also relates to a preparation method of the catalyst and its application in prehydrogenation of sulfur-containing and chlorine-containing C9 petroleum resin. Background technique [0002] C9 petroleum resin is a light yellow to dark brown functional resin with a relative molecular weight of 200-3000 and a softening point of 80-140°C. It is a glassy thermoplastic solid at room temperature. At present, the main source of preparing C9 petroleum resin is the by-product of petroleum cracking ethylene. Due to the complex composition of cracking raw materials and the relatively backward production process and production technology of petroleum resin, petroleum resin has deep color and poor stability, especially double bonds, benzene rings, etc. And the presence of a small amount of impurities such as S and N affects the color, stability and compatibility with other resins of t...
