ABSTRACT:
A process for upgrading a light olefin feed by converting the 1-olefins to higher molecular weight oligomers and the iso-oleins to fuel ethers or alcohols. The process provides substantial improvements in the production of lower alkyl tertiary alkyl ethers or tertiary alkyl alcohol, such as methyl tertiary butyl ether (MTBE), methyl tertiary amyl ether (TAME) or tertiary butyl alcohol. The 1-olefin component of the hydrocarbon feedstream is separated by selective oligomerization in contact with a reduced chromium oxide catalyst to form an olefin oligomer of higher molecular weight, such as gasoline, distillate and lube range hydrocarbons. The iso-olefins are separated by etherification with a lower alcohol such as methanol or by hydration to form an alcohol such as tertiary butanol. The oligomerization process can be integrated either upstream or downstream of the etherification step.
