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

Abstract

The invention discloses a sectional feeding type alkylation reactor and an alkylation reaction method. The reactor comprises a reactor barrel body, a seal head, a separating plate, an upper bed layer, a lower bed layer, a feeding pipe, a fed material distributing pipe, a rotating shaft, a supplementing material inlet, a discharging opening, a circulating cooling air inlet and a circulating cooling air outlet. The invention further provides the alkylation reaction method adopting the sectional feeding type alkylation reactor. The alkylation reaction method comprises the following steps: preparing acid hydrocarbon emulsion through iso-butane and concentrated sulfuric acid in the upper bed layer, and then entering a rotating bed at the lower bed layer together with mixed hydrocarbon which enters through a supplemented material inlet, so as to perform alkylation reaction.

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 that adopts isobutane and C3-C5 olefins to feed in stages to catalyze the alkylation reaction. chemical reaction method. 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 ...
