摘要： Systems and methods are provided for integration of electrolysis with biomass gasification to generate synthesis gas that can be used for production of renewable fuels and/or other hydrocarbonaceous compounds. The hydrocarbonaceous compounds can include compounds formed by chemical synthesis, such as alkanes formed by a Fischer-Tropsch process or methanol formed by a methanol synthesis process; or the hydrocarbonaceous compounds can include compounds formed by fermentation, such as alcohols formed by micro-organisms that use the synthesis gas as an input feed.

摘要： Methods and systems producing gasoline boiling range hydrocarbons from light paraffins are disclosed. Such methods may include exposing a paraffin-containing stream to a catalyst in a side riser of a fluid catalytic cracking reactor under effective conditions for dehydrogenating at least a portion of paraffins in the stream into olefins and thereby producing an olefin-containing stream, wherein the paraffin-containing stream comprises greater than 50 wt % isobutane; and alkylating olefins in the olefin-containing stream to produce a product stream comprising an alkylate fraction comprising hydrocarbons boiling between 100° F. and 400° F.

摘要： 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.
