The conversion method of the olefinic hydrocarbons using a spent FCC catalyst

摘要

(57) Abstract Using the used FCC catalytic converter, the manner which transforms the olefin hydrocarbon is disclosed. The said manner, oligomer conversion possible olefin, desirably propylene and ethylene, with gasoline, in order quality it improves to convert to C₄ /C5 olefins and in paraffin, is something which uses the used FCC catalytic converter which contains the used FCC additive optionally or in addition to this, the reactor of FCCU/in the stripper section in place of the quality improvement conversion device of another olefin, feed stock, is the products current of FCCU which contains propylene/the ethylene for example like the overhead distillate the absorption tower and the depropanizing tower.
