METHOD OF INCREASING OUTPUT FROM ISOMERIZATION ZONE Russian patent published in 2018 - IPC C07C5/27 C07C7/04 C07C9/15 C07C9/10 

FIELD: chemical industry.

SUBSTANCE: invention relates to a method of increasing the output from the isomerization zone, which involves the separation of part C₆ cyclic hydrocarbons from a naphtha stream containing C₄₊ hydrocarbons, to obtain a stream depleted in C₆ cyclic hydrocarbons; branch of C₄ hydrocarbons, isoC₅ hydrocarbons and isoC₆ hydrocarbons from the stream depleted in C₆ cyclic hydrocarbons; and direction of at least one stream enriched in isoC₄ hydrocarbons, isoC₅ hydrocarbons, isoC₆ hydrocarbons, or combinations thereof, in the isomerization zone.

EFFECT: method makes it possible to effectively and efficiently convert isohydrocarbons into normal paraffins in the same isomerization zone.
