METHOD OF ALKYLATING AROMATIC HYDROCARBONS WITH OLEFINS AND A REACTION-RECTIFICATION SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC B01J29/00 

FIELD: technological processes.

SUBSTANCE: reaction-rectification system for producing alkylated aromatic hydrocarbons contains at least one catalytic reaction zone which is an alkylation reaction zone of at least one olefin, wherein movement of reagents in the reaction zone is co-directional and upward, mainly unreacted substances are discharged from the system from the system and partially returned to the reaction zone, partially as an upper reflux of the column, and reaction products are output by the lower product. System may have at least one side sampling for removal of the component most selectively formed during the reaction. Besides the alkylation reaction zone, the system can additionally contain a zone of transalkylation of aromatic compounds by alkylation reaction products. System can have an installed vertical partition in at least one distillation section of the apparatus to increase efficiency of separation of reagents.

EFFECT: disclosed is a reaction-rectification system for producing alkylated aromatic hydrocarbons.
