Abstract
Abstract Olefin containing mixtures are converted into olefinic gasoline blending stock with an excellent research octane number and in good yield by passage over a catalyst comprising a highly siliceous zeolite having a silica to alumina mole ratio of at least 200 to 1 and a constraint index within the approximate range of 1 to 12.

Claim 1
Independent Claim
103 words
An improved process for producing a gasoline fraction having no more than about 20 percent by weight of aromatics, said process comprising contacting a C 2 -C 5 olefin containing mixture with a catalyst comprising a zeolite having a silica to alumina mole ratio of at least 200 to 1 and a constraint index in the approximate range of 1 to 12 at a temperature between 450°F (233°c) and 800°F (427°c), an olefin partial pressure between 0.5 psia (4 k Pa) and 100 psia 689 (k Pa) and a WHSV between 0.1 and 25, and recovering a gasoline fraction containing predominantly higher olefins.
Claim 2
Dependent Claim
103 words
