ABSTRACT:
A process is provided for upgrading the olefinic gasoline by-product of low-severity medium-pore zeolite catalyzed hydrocarbon conversion processes including catalytic dewaxing and olefin oligomerization. The olefinic gasoline stream is upgraded in a high-severity catalytic conversion process which may be carried out in a catalytic cracking unit primary or secondary riser reactor or in a second medium-pore zeolite-catalyzed reaction zone. The olefinic gasoline stream may be mixed with a C.sub.2 -C.sub.7 aliphatic stream before upgrading the mixture in the high-severity catalytic conversion process. Examples of such low-severity medium-pore zeolite catalyzed hydrocarbon conversion processes include distillate and lubricant dewaxing as well as olefin oligomerization.
