Abstract
A two-stage catalytic conversion process for converting an olefins-containing feed is disclosed which comprises contacting the feed in a first stage under substantially non-oligomerizing conditions with a catalyst comprising at least one metal (X) selected from the group consisting of metals from Groups 1a, 1b, 2a, 2b, 4b, 5b, 6b and 8 of the Periodic Table of the Elements and contacting the effluent from the first stage in the second stage under olefin oligomerization conditions at a temperature which is at least 50.degree. C. above the operating temperature of the first stage with a catalyst comprising at least one metal (Z) selected from the group consisting of metals from Groups 1b, 2a, 2b, 4b, 5b, 6b, and 8 on a mordenite-type of crystalline trivalent metal (Q) silicate.
