Abstract
A process for increasing the yield of C.sub.10 plus hydrocarbon products from a Fischer-Tropsch plant which comprises (a) recovering a Fischer-Tropsch condensate fraction boiling below about 700 degrees F. from the Fischer-Tropsch plant, wherein said fraction contains at least 10 weight percent and preferably more olefins; (b) contacting the olefins in the Fischer-Tropsch condensate fraction under oligomerization conditions, at a reaction temperature between about 650 degrees F. and 800 degrees F. with an oligomerization catalyst comprising active chromium on an inert support; and (c) recovering a C.sub.10 plus hydrocarbon product.
