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

Abstract

The invention discloses a sectional feed alkylation reactor and an alkylation reaction method. The reactor comprises a reactor cylinder, a sealing head, a partition plate, an upper bed layer, a rotating bed, a composite bed layer, a feed pipe, a feed distribution pipe, a rotating shaft, a material supply inlet, a discharge outlet, a circulating cooling gas inlet and a circulating cooling gas outlet. The invention further provides an alkylation reaction method, which comprises the following steps: by adopting the sectional feed alkylation reactor, iso-butane and concentrated sulfuric acid are firstly mixed to form acid hydrocarbon emulsion in the upper bed layer, then the hydrocarbon emulsion and mixed hydrocarbon, entering from the material supply inlet, enter the rotating bed for performing alkylation reaction, and the reacted material can realize the demulsification process of the emulsion in the composite bed layer.

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 ...
