Abstract: In a process for upgrading an ethane-containing C5− paraffin stream, the paraffin stream is contacted with an oxygen containing gas in the presence of a selective oxidation catalyst under conditions to selectively oxidize at least part of the ethane in the paraffin stream and produce a first product stream comprising ethylene. At least part of the first product stream is then with an oligomerization catalyst under conditions to oligomerize at least part of the ethylene and produce a second product stream comprising gasoline and/or distillate boiling range hydrocarbons. Gasoline and/or distillate boiling range hydrocarbons are then recovered from the second product stream and at least a part of any residual C5− paraffin stream is recycled to the selective oxidation step.

Abstract: Systems and methods are provided for forming alkylate from an isoparaffin-containing feed. Olefins for the alkylation reaction can be generated from a portion of the isoparaffin-containing feed. This can be achieved, for example, by using selective oxidation to convert a portion of isoparaffins into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate alkylation of isoparaffin using the in-situ formed alkenes. A catalyst having an MWW framework is an example of a suitable solid acid catalyst.

Abstract: A process for upgrading an ethane-containing C5− paraffin stream comprises contacting the paraffin stream with an oxygen containing gas in the presence of a selective oxidation catalyst under conditions to selectively oxidize at least part of the ethane in the paraffin stream and produce a first product stream comprising ethylene. At least part of the first product stream may then be contacted with an isoparaffin-containing feed in the presence of a solid alkylation catalyst and under conditions to alkylate at least part of the isoparaffin with at least part of the ethylene and produce a second product stream comprising C6+ alkylate. Alternatively, at least part of the ethylene in the first product stream may be dimerized before the alkylation step.
