METHODS AND DEVICES FOR INTEGRATED PROCESS OF ISOMERISATION AND PLATFORMING Russian patent published in 2019 - IPC C10G59/00 C10G63/00 

FIELD: chemistry.

SUBSTANCE: disclosed is a method for isomerisation and reforming of hydrocarbons, involving: feeding a feed stream containing C₅₊ hydrocarbons into separation device to form first hydrocarbon flow containing mainly C₅-C₆ hydrocarbons, and a second hydrocarbon stream containing mainly C₇₊ hydrocarbons; supply of first flow of hydrocarbon material containing mainly C₅-C₆ hydrocarbons, into a first isomerisation reaction zone containing a first isomerisation catalyst to form a stream exiting the first isomerisation reaction zone; feeding a stream leaving the first isomerisation reaction zone to an isohexane recovery column to obtain a stream exiting the isohexane release column which is fed for recycling into the first isomerisation reaction zone; feeding a second hydrocarbon stream containing mainly C₇₊ hydrocarbons into a reforming zone to obtain a stream exiting the reforming zone; feeding a stream leaving the reforming zone to a separator to form a first recovered hydrocarbon stream containing C₇ hydrocarbons, and a second recovered hydrocarbon stream containing C₈₊ hydrocarbons; and supply of first extracted hydrocarbon flow containing C₇ hydrocarbons, to a second isomerisation reaction zone containing a second isomerisation catalyst to obtain a stream exiting the second isomerisation reaction zone. Also disclosed is a device for isomerisation and reforming of hydrocarbons in accordance with the method described above.

EFFECT: technical result is creation of accessible and improved processes, which would allow to obtain gasoline by direct mixing of product of isomerisation and product of reforming.
