摘要： Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization. The process comprises selecting waste plastics containing polyethylene and/or polypropylene and preparing a stable blend of petroleum and the selected plastic. The amount of plastic in the blend comprises no more than 20 wt. % of the blend. The blend is passed to a refinery FCC unit. A liquid petroleum gas LPG olefin/paraffin mixture and naphtha are recovered from the FCC unit and passed to a steam cracker to make ethylene.

摘要： Provided is a composition comprising a blend of a waste plastic and a bio feedstock. Also provided is a process for preparing a stable blend of a plastic and bio feedstock which can be stored or transported if desired. The amount of plastic in the blend comprises no more than 20 wt. % of the blend. The blend can be passed to a conversion unit for conversion of the waste plastic and bio feedstock. The conversion process produces clean monomers for polymerization and chemical intermediates.

摘要： 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. 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. Then cooling the plastic melt and petroleum feedstock liquid blend with mixing to a temperature below the melting point of the plastic.

摘要： Provided is a continuous process for converting waste plastic into recycle for polypropylene polymerization. The process comprises selecting waste plastics containing polyethylene and/or polypropylene and preparing a stable blend of petroleum and the selected plastic. The amount of plastic in the blend comprises no more than 20 wt. % of the blend. The blend is passed to a refinery FCC unit. A liquid petroleum gas C3 olefin/paraffin mixture is recovered from the FCC unit. The C3 paraffins and C3 olefins are separated into different fractions with the C3 olefin fraction passed to a propylene polymerization reactor, and the C3 paraffin fraction passed optionally to a dehydrogenation unit to produce additional propylene.
