摘要
Disclosed is a process for converting olefinic hydrocarbons using spent FCC catalysts which comprises using spent FCC catalysts, optionally containing spent FCC additives, in the reactor/stripper part of the FCCU, instead of or in addition to a separate olefin upgrader, to upgrade C2-C8 oligomerizable olefins, preferably propylene and ethylene, into C4/C5 olefins and isoparaffins as well as gasoline, wherein feedstock can be product streams of the FCCU containing propylene/ethylene such as, for example, the absorber and depropanizer overheads.
