Problems solved by technology

[0008] The main problem faced by the above solid acid catalysts is that the life of the catalyst is too short or the selectivity is not good or the regeneration is difficult. Therefore, in order to solve these problems, it is necessary to continue to look for new catalytic materials with excellent performance, and to design catalysts in conjunction with engineering technology development. Actively cooperate in order to develop a safe, clean and high-quality solid acid alkylation process

Abstract

The invention provides a resin catalyst used in an alkylation reaction of isobutene and butylene. The resin catalyst is obtained by performing suspension polymerization on three monomers, i.e., styrene, divinylbenzene and N-[4-(sulfanilic amide) phenyl]acrylamide, extracting wax, sulfonating and engaging. A resin catalyst framework is provided with a sulfonic acid group and a sulfamide group. Thecatalyst is provided with the sulfamide group, is oleophilic and has higher compatibility with isobutene and butylene, and the concentrations of the isobutene and butylene on the catalyst are increased, so that the catalytic activity is raised, the service life is long, the selectivity is high, and the resin catalyst can be popularized and applied on a production device. The invention further provides a preparation method of the catalyst.

Description

technical field [0001] The invention relates to a resin catalyst method, in particular to a resin catalyst for the alkylation reaction of isobutane and butene and a preparation method thereof. Background technique [0002] In the oil refining industry, the alkylation reaction refers to the reaction of isobutane with olefins under the action of strong acid to generate alkylated oil. Because alkylate is a non-olefinic, non-aromatic, low-sulfur, low-vapor-pressure, high-octane mixture of alkanes, it is an ideal gasoline blending component. [0003] Alkylation process can be divided into liquid acid alkylation process and solid acid alkylation process. Currently the most widely used is the liquid acid alkylation process and its improved process. The liquid acid alkylation process widely used in industry includes H 2 SO 4 Alkylation by HF method and alkylation by HF method, because the two alkylation processes have their own characteristics in terms of technology, and they ar...
