ABSTRACT:
Lead free gasoline of high octane number is obtained from C.sub.3 and C.sub.4 olefinic cuts as follows: propylene contained in the C.sub.3 cut is oligomerized, at least 80% of the isobutene and less than 40% of the n-butenes of the C.sub.4 cut are oligomerized to form an oligomerizate distilling in the gasoline range, which is separated from the unreacted C.sub.4 hydrocarbons, the latter are subsequently alkylated to form a gasoline fraction which can be admixed with the oligomerizates of the C.sub.3 and the C.sub.4 cuts to produce the desired high octane gasoline.
