Patent number: 6395945Abstract: A novel integrated olefin processing scheme is provided where olefins and paraffins are processed to produce high octane gasoline blending components. The integrated process involves the processing of olefins by hydroisomerization to produce a hydroisomerate stream which is subsequently alkylated in an alkylation process with branched chain paraffin hydrocarbons to produce an alkylate product. The alkylate product can further be separated into various fractions, including propane, n-butane, i-butane and a C5+ alkylate stream. The C5+ alkylate stream can be separated into an i-pentane stream and a deisopentanized C5+ alkylate stream.Type: GrantFiled: March 31, 2000Date of Patent: May 28, 2002Assignee: Phillips Petroleum CompanyInventor: Bruce B.
