Abstract: A process for producing renewable distillate-range hydrocarbons is provided. The process includes dehydrating a renewable C2-C6 alcohol feedstock to produce an olefin, oligomerizing the olefin the presence of a halometallate ionic liquid catalyst to produce an oligomer product and hydrogenating the oligomer product or fractions thereof to produce saturated distillate-range hydrocarbons.

Abstract: A process is provided for removing organic chlorides from glyceride oil. The process includes the steps of (a) reacting a glyceride oil comprising organic chlorides with a liquid aqueous system at a temperature of at least 80° C. to form a treated glyceride oil and (b) separating the treated glyceride oil from the liquid aqueous system. The treated glyceride oil has a reduced concentration of organic chlorides compared to the glyceride oil reacted in step (a).
