    Abstract: Provided is a blend of a petroleum 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 and less than 100 ppm chloride. A process for preparing a 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 in the range of from 550° F. to 700° F. The blend mixture is then hot filtered and then optionally treated with a chloride removal guard bed. The resulting blend can then be cooled and stored or sent directly to a refinery conversion unit.

    Abstract: A method includes combusting a fuel stream in a combustion unit in the presence of a first oxygen enriched carbon dioxide stream received from an anode of an electrolyzer to generate a hot flue gas stream comprising carbon dioxide, steam, unconsumed oxygen, NOx and SOx, cooling the hot flue gas stream in a heat exchanger by supplying a water stream to the heat exchanger as a heat transfer medium to generate a cooled flue gas stream effluent, processing the cooled flue gas stream effluent in one or more separation units to generate a carbon dioxide rich gas stream and a carbon dioxide lean gas stream, and passing the carbon dioxide rich gas stream to the anode of the electrolyzer to generate a second oxygen enriched carbon dioxide stream for sending to the combustion unit.

    Abstract: Disclosed herein is a method for making diesel, gasoline and LPG comprising coprocessing a petroleum-derived feedstock with up to 50 wt. %, relative to the total weight of the feedstocks, of a lipid-containing feedstock in the presence of a catalyst under fluidized catalyst cracking conditions. Also disclosed herein is a method for making a diesel fuel or a combined diesel and gasoline fuel by injecting up to 50 wt. %, relative to the total weight of the feedstocks, of a lipid-containing feedstock to a stripper or a riser quench downstream from a petroleum derived feedstock injection point in a fluid catalytic cracking unit.
