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.

Abstract: An organotemplate-free synthetic process for the production of a zeolite of TON framework type structure is provided. The process includes the steps of: (1) preparing a mixture comprising: (a) an alumina-coated silica; (b) a source of an alkali metal; (c) an alcohol; (d) a source of hydroxide ions; (e) seed crystals comprising a zeolitic material having a TON framework type structure; and (f) water; and (2) crystallizing the mixture obtained in step (1).

Abstract: A method is disclosed making a molecular of TON framework type having unique properties. The method uses 1,3,4-trimethylimidazolium cations as a structure directing agent and a combined source of silicon and aluminum selected from alumina-coated silica and aluminosilicate zeolites. The obtained molecular sieve can be used in processes for dewaxing paraffinic hydrocarbon feedstocks.

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.
