Patent ID: 8319000

Claim:
A process for reacting an iso-pentane, comprising: alkylating the iso-pentane with a converted olefinic feedstock comprising at least 5 wt. % C5 olefins in the presence of an ionic liquid catalyst mixed with a hydrogen halide or an alkyl halide, wherein the ionic liquid catalyst is selected from the group consisting of a hydrocarbyl substituted pyridinium chloroaluminate, a hydrocarbyl substituted imidazolium chloroaluminate, and mixtures thereof, wherein the C5 olefins in the converted olefinic feedstock are predominantly 2-pentene, to make a naphtha and a middle distillate, and wherein a formation of iso-butane during the alkylating is less than 20 wt. % of an amount of olefins in the converted olefinic feedstock.
