METHOD OF CONVERTING HEAVY MATERIAL INTO PETROL AND PROPYLENE WITH CONTROLLED OUTPUT Russian patent published in 2013 - IPC C07C2/04 C07C4/06 C07C11/06 C10G63/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for combined production of petrol and propylene from heavy hydrocarbon material with initial boiling point of 340°C on a catalytic cracking apparatus (FCC), downstream of which there is an oligomerisation apparatus, capable of operating in two modes designated as "maximum propylene" and "maximum petrol", wherein for the "maximum propylene" mode, material fed into the oligomerisation apparatus consists of a C4 or C4/C5 olefin fraction, for the "maximum petrol" mode, material fed into the oligomerisation apparatus consists of a C3/C4 olefin fraction; catalytic cracking is carried out in a single reactor or in two different reactors, each reactor capable of operating in an ascending stream. The invention also relates to a method where catalytic cracking is carried out in a single reactor or in two different reactors, each reactor capable of operating in a descending stream.

EFFECT: improved flexibility of the method with respect to production of propylene and petrol.
