FIELD: chemistry.
SUBSTANCE: present invention relates to an alkylation reaction apparatus, which is characterized by the presence of n reactors, wherein in said n reactors there are m reactors comprising a first reactor which has three reaction zones as defined below; according to the direction of the alkylation reaction streams, said three reaction zones represent a zone x of reaction, a zone y of reaction and a zone z of reaction, respectively; wherein based on the mixing intensity of the zone y of reaction > the mixing intensity of the zone x of reaction > mixing intensity of the zone z of reaction, where n ≥ 1 and n ≥ m, wherein reactor equipped with three reaction zones has inner diameters Rx of reaction zone for zone x of reaction, Ry of reaction zone for zone y of reaction and Rz of reaction zone for zone z of reaction, respectively, wherein Rz of reaction zone > Rx of reaction zone > Rz of reaction zone. Present invention also provides a system for carrying out an alkylation reaction, comprising said apparatus for carrying out an alkylation reaction, and a liquid acid-catalysed alkylation reaction using said alkylation reaction apparatus or said alkylation reaction system.
EFFECT: use of the disclosed invention increases intensity of dispersion in the emulsion of the acid and hydrocarbon during the initial reaction of the alkene, intensifies the solubility of the isoalkane in the liquid acid and accelerates the reaction of hydrogen transfer.
