Summary: | 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 10 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 above the melting point of the plastic, but less than 500° F. The blend mixture is then hot filtered with the resulting filtered blend mixture being heated to at least 500° F. The heated mixture can then be treated with a chloride removal guard bed. The resulting blend can then be cooled and stored or sent directly to a refinery conversion unit. |
