Alkylation reactor and alkylation process method

Abstract

The invention discloses an alkylation reactor and an alkylation process method. The reactor comprises a reactor tube body, closure heads, a revolving bed, a charging pipe, a charge distribution pipe, a discharging opening, a circulating cooling gas inlet, a circulating cooling gas refrigeration system and a circulating cooling gas outlet, wherein a closed reactor shell body is formed by the reactor tube body and the closure heads, and the revolving bed is vertically located at the internal middle part of the shell body; a sealing member is arranged between the upper part of the revolving bed and the reactor shell body, the upper part of the revolving bed and the sealing member are of rotatable connection, the circulating cooling gas inlet and the circulating cooling gas outlet are respectively formed in the shell body at the upper and lower sides of the sealing member, and the circulating cooling gas refrigeration system is located between the circulating cooling gas inlet and the circulating cooling gas outlet. According to the alkylation method disclosed by the invention, alkylation reaction is carried out by taking concentrated sulfuric acid as a catalyst and taking isobutane and alkene as raw materials. According to the alkylation reactor and the alkylation process method, the alkylation reaction can be carried out at low temperature, the acid consumption is low, and the equipment scale is small.

Description

technical field [0001] The invention relates to an alkylation reactor and an alkylation reaction method, in particular to an alkylation reactor and an alkylation reaction method which adopt isobutane and C3-C5 olefins to catalyze the alkylation reaction. Background technique [0002] With the development of the economy, especially the rapid development of the transportation industry, the emission of vehicle exhaust is one of the main sources of air pollution. Improving the quality of gasoline is the most important way to reduce the pollution of vehicle exhaust. The alkylated oil obtained by the alkylation reaction of isobutane and C3-C5 olefins has the characteristics of no sulfur, high octane number, small difference between the octane number of the research method and the octane number of the motor method, and is a high-quality An important blending component of clean gasoline. [0003] Alkylation reaction is a traditional technology in the field of petroleum refining, ma...

AI Technical Summary

Problems solved by technology

This reactor is not suitable for the sulfuric acid alkylation reaction process, because the heat exchange method adopted is the heat extraction method of circulating materials, which is not suitable for the sulfuric acid alkylation reaction with large exothermic heat. The liquid storage tank at the lower part of the reactor and The use of reaction material circulation operation mode will increase the side reaction
