Claim 16:
17. A method of upgrading products obtained by thermolysis or pyrolysis of solid plastic waste, the method comprising:
obtaining a quenched liquid, condensed gases, or pyrolysis vapors from thermolysis or pyrolysis of solid plastic waste;
contacting the quenched liquid, condensed gases, or pyrolysis vapors with a fine mineral matter derived from coal and/or mined from natural resources including volcanic basalt, glacial rock dust deposits, iron potassium silicate and/or sea shore deposits with particle sizes ranging from about 1 micron to less than about 2,000 microns, wherein the fine mineral comprises at least one metal selected from the group consisting of Fe, Cu, Mn, Al, Zn, or combinations thereof at the following concentrations:
Fe 14,000 to 45,000 ppm;
Cu 10 to 300 ppm;
Mn 100 to 1,500 ppm;
Al 3,000 to 25,000; and
Zn 20 to 300 ppm; and

separating the quenched liquid, condensed gases, pyrolysis vapors from the fine mineral matter.
