METHOD OF GASOLINE FRACTION REPROCESSING Russian patent published in 1994 - IPC

FIELD: petroleum chemistry. SUBSTANCE: reforming of gasoline fractions is carried out in the presence of catalyst containing, wt.-%: platinum or a mixture of platinum with promoter 0.2-1.2; nonacid medium-porous zeolite with modulus 25-1000, value of ammonia desorption is 0.05-0.30 mmole/g 40-75, and aluminium oxide - the rest, and then - in the presence of catalyst of the following composition, wt.-%: platinum or a mixture of platinum with promoter 0.3-1.2; chlorine 0.5-2.5, and aluminium oxide - the rest. Process is carried out at the mass ratio of catalysts (0.33-10):1, at 440-530 C, under pressure 1-4 MPa. EFFECT: improved method of reprocessing. 2 cl, 1 tbl
