METHOD OF PRODUCING ALKYLBENZINES IN CATALYTIC REACTOR WITH INTERNAL AXIAL DISTRIBUTION OF ALKYLATING AGENT Russian patent published in 2020 - IPC B01J8/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical technology of oil refining industry, namely to methods of producing high-octane gasoline components from liquefied hydrocarbon gases. Method of alkylating isoalkanes C₄-C₅ olefins C₂-C₅ in reactor with fixed bed of solid catalyst involves introduction of stream of alkylating agent into reaction space of reactor through distributor of cylindrical shape, located inside the reactor, having holes directed against movement of the stream containing the alkylated component, intra-axis distribution of alkylating agent flow throughout the length of the reaction zone and feeding the alkylated component to the catalyst through a bed of regular or bulk packing, where the stream containing the alkylated component is mixed with a stream containing an alkylating agent.

EFFECT: invention provides efficient distribution of alkylating agent on a catalyst layer operating in flow mode.
