A process for catalytic conversion of hydrocarbon feedstock to produce isobutanenand isoparaffin-enriched gasoline which comprises two different reactions, thenpreheated feedstock is contacted with hot regenerated catalyst in the lower part ofna reactor with the result that catalytic cracking reaction takes place, and thenmixture of vapors and the coke deposited catalyst are up-flowed and enter into ansuitable reaction environment with the result that isomerization and hydrogenntransfer reaction take place. The produced LPG has an isobutane content of aboutn20wt% to about 40wt% and the produced gasoline contains isoparaffin content ofnabout 30wt% to about 45wt% and olefin content of less than 30wt%. RON andnMON of the gasoline are 90∼93 and 80∼84 respectively. |
