METHODS AND SYSTEMS FOR CONVERTING PLASTIC TO FUEL

摘要

A method for producing a vapor stream from waste plastic comprises providing a waste plastic feedstock into a reactor containing one or more residues produced from a previously heated source of waste plastic, and heating the waste plastic feedstock in the reactor to a temperature from about 125° C. to 500° C. to generate a vapor containing one or more hydrocarbons. The waste plastic feedstock can have a calcium to sodium mass ratio from about 0.0001 to 400 as measured by inductively-coupled plasma (ICP) spectrometry. The catalytic activity in the reactor may be provided through one or more constituent elements in the waste plastic feedstock or the one or more residues produced from the previously heated source of waste plastic.

1. A method for producing a condensate from waste plastic, comprising:
a. providing a waste plastic feedstock into a reactor containing one or more residues produced from a previously heated source of waste plastic, wherein the waste plastic feedstock includes at least one of a tire and an electrical component casing, and wherein said residue has a calcium-to-sodium mass ratio from about 0.0001 to 400 as measured by inductively-coupled plasma (ICP) spectrometry; b. heating said waste plastic feedstock in said reactor to a temperature from about 125° C. to 500° C. to generate a vapor containing one or more hydrocarbons; c. condensing said vapor to generate said condensate comprising said one or more hydrocarbons; and d. collecting said condensate in a collection vessel, wherein said condensate comprises between about 20 g and 75 g of said one or more hydrocarbons per 100 g of said waste plastic and said one or more residues.
