Abstract (en)

[origin: EP1046696A2] A catalytic transform process for reducing the content of olefin in liquefied gas and gasoline features that in the complex reactor composed of lifting tube or lifting tube and fluidized bed, preheated raw oil comes into lifting tube from its lower end and is contacted with catalyst, the oily gas generated after reaction is lifted up to middle or top of lifting tube, where it is in contact with cooled catalyst for continuous reaction, the resultant flowing out after reaction comes into settler, the reaction resultant is separated. The catalyst is divided into two portions after stripped and regenerated, one coming into lower end of lifting tube and another into middle or top of lifting tube. With said process, the butylene in liquefied gas is decreased to 17.5 wt.% and the isobutane in it is increased to 37.04 wt.%, and the olefin in gasoline is decreased to 12.32 wt.% and the isoparaffin in it is increased to 41.83 wt.%.

[origin: EP1046696A2] A process for catalytic conversion of hydrocarbon feedstock to produce isobutane and isoparaffin-enriched gasoline which comprises two different reactions, the preheated feedstock is contacted with hot regenerated catalyst in the lower part of a reactor with the result that catalytic cracking reaction takes place, and the mixture of vapors and the coke deposited catalyst are up-flowed and enter into a suitable reaction environment with the result that isomerization and hydrogen transfer reaction take place. The produced LPG has an isobutane content of about 20wt% to about 40wt% and the produced gasoline contains isoparaffin content of about 30wt% to about 45wt% and olefin content of less than 30wt%. RON and MON of the gasoline are 90 SIMILAR 93 and 80 SIMILAR 84 respectively. <IMAGE>
