FIELD: petrochemical industry; other industries; method of production of the alkylate by the sulfuric-acid alkylation in the multiphase reactor.
SUBSTANCE: the invention is pertaining to the method of production of the alkylate by the sulfuric-acid alkylation in the multiphase reactor, in which the hydraulic mode is provided, which forms the pulsations for attaining the best commixing and the combined interphase mass-transfer and the heat-transfer. The method provides for feeding of the hydrocarbon component consisting of the olefin, the olefin predecessor or their mixture and isoalkane at least partially in the gaseous state into the reactor with the down flow in the presence of the liquid sulfuric acid, and with the internal static system of mixing. The liquid sulfuric acid is fed with constant speed, and the speed of feeding of the olefin, the olefin predecessor or their mixture is increasing until the pressure fall sufficient for formation of the pulsating flow. The internal static system of mixing contains the head including the structure for contacting, which has the free space exceeding 50 % of the volume. The system of the heads may consist of the materials, which are either inert, or catalytically active by their nature.
EFFECT: the invention ensures production of the alkylate by the sulfuric-acid alkylation in the multiphase reactor providing formation of the pulsations for attaining the best commixing and the corresponding interphase mass-transfer and the heat-transfer.
