A process for conversion of crude hydrocarbon mixtures comprising tertiary olefins and gum-forming constituents with an alcohol in the presence of hydrogen, which process comprises contacting the crude hydrocarbon mixture, the alcohol, and hydrogen with a catalyst comprising an acidic molecular sieve containing an active hydrogenation metal component, as well as a stabilized crude hydrocarbon mixture containing alkyl tertiary alkyl ethers. A process for conversion of a tertiary olefin which contains one or more additional ethylenically or acetylenically unsaturated bonds. |
