Abstract
A process for producing a jet fuel, comprising contacting an olefin and an isoparaffin with an unsupported catalyst system comprising an ionic liquid catalyst and a halide containing additive in an alkylation zone under alkylation conditions to make an alkylate product, and recovering the jet fuel from the alkylate product, wherein the jet fuel has a NMR branching index greater than 60 and meets the boiling point, flash point, smoke point, heat of combustion, and freeze point requirements for Jet A-1 fuel. Also a process for producing a jet fuel, comprising providing a feed produced in a FC cracker comprising olefins, mixing the feed with an isoparaffin, alkylating the mixed feed in an ionic liquid alkylation zone, and separating the jet fuel from the alkylated product.
