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: Provided is a stable blend of a petroleum atmospheric tower bottoms (ATBs) feedstock and 1-20 wt. % of plastic, based on the weight of the blend, with the plastic comprising polyethylene and/or polypropylene, and the plastic in the blend comprising finely dispersed microcrystalline particles having an average particle size of 10 micron to less than 100 microns. A process for preparing a stable blend of plastic and petroleum is provided, comprising mixing together a petroleum feed and a plastic comprising polyethylene and/or polypropylene and heating the mixture above the melting point of the plastic, but less than 500° F. Then cooling the plastic melt and petroleum feedstock liquid blend with mixing to a temperature below the melting point of the plastic.

Abstract: A process is provided for producing a liquid hydrocarbon material suitable for use as a fuel or as a blending component in a fuel. The process includes co-processing a pyrolysis oil derived from a waste plastic raw material and a biorenewable feedstock comprising triglycerides in a catalytic cracking process in a presence of a solid catalyst at catalytic cracking conditions to provide a cracking product. The cracking product may be fractionated to provide at least one of a gasoline fraction and a middle distillate fraction.
