Claim 19:
20. 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 supported catalyst, the supported catalyst comprises an iron (Fe) on a fine mineral matter matrix, a manganese (Mn) on a fine mineral matter matrix, a copper (Cu) on a fine mineral matter matrix, or a combination thereof, the supported catalyst is applied in concentrations between 0.5 and 10%, wherein the fine mineral matter has a range of particle sizes between 1 micron and about 2,000 microns and 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, or pyrolysis vapors from the fine mineral matter.
