FIELD: chemical engineering.
SUBSTANCE: device comprises first vertical section, second vertical section, vertical pipe, and separating vessel. The radius of the first section is related to that of the second section as 1.1:1-5.0:1. The bottom space of the first section receives means for supplying hydrocarbon raw material and means for supplying cracking catalyzer for selective catalytic cracking into gasoline. The second section is connected with the first one by means of an adapting section. The vessel is additionally provided with the outlet opening for discharging separated gases of cracking from the separation device. The method comprises cracking hydrocarbon raw material and cracking intermediate cracking product enriched by propene and butenes .
EFFECT: improved cracking.
