Abstract
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.
Claims12
A method for processing a hydrocarbon feedstock comprising at least one C5 olefin comprising the steps of:
- a) hydroisomerizing said hydrocarbon feedstock in a hydroisomerization zone so as to produce a hydroisomerate stream, wherein said hydroisomerate stream does not pass through an etherification zone;
- and
- b) alkylating at least a portion of said hydroisomerate stream by a branched chain paraffin hydrocarbon in an alkylation unit to produce an alkylate stream.
