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: The present disclosure is directed to novel germanosilicate compositions and methods of producing and using the same. In particular, this disclosure describes new germanosilicates of CIT-14 topology. The disclosure also describes methods of preparing and using these new germanosilicate compositions as well as the compositions themselves.

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 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.

Abstract: The present disclosure is directed to novel germanosilicate compositions and methods of producing the same. In particular, this disclosure describes an array of transformations originating from the extra-large-pore crystalline germanosilicate compositions, designated CIT-13, possessing 10- and 14-membered rings. Included among the new materials are the new phyllosilicate compositions, designated CIT-13P, new crystalline microporous germanosilicates including high silica versions of CIT-5 and CIT-13, with and without added metal oxides, and new germanosilicate compounds designated CIT-14 and CIT-15. The disclosure also describes methods of preparing these new germanosilicate compositions as well as the compositions themselves.
