-22. (canceled)
A composition comprising made by a process comprising the steps:
- (a) providing a waste plastic to a reactor;
- (b) contacting the waste plastic with a catalyst to form a reaction mixture;
- and
- (c) applying microwave radiation to the reaction mixture;
- thereby forming a value-added product;
- wherein the catalyst comprises a zeolite, a solid acid catalyst, rare-earth metal oxide catalyst, or a combination thereof;
- and
- wherein the value-added product comprises benzene, toluene, xylenes, ethylene, propylene, butene, hydrogen, methane, or a combination thereof;
- wherein the rare-earth metal oxide catalyst comprises a catalyst metal comprising at least one metal selected from Groups 6-12 and a catalyst support selected from CeO2, La2O3, and combinations thereof;
- wherein the microwave irradiation induces bulk temperatures in the reaction mixture of from about 180° C. to about 400° C.;
- wherein the composition comprises hydrogen and at least one hydrocarbon selected from benzene, toluene, xylenes, ethylene, propylene, butene, and methane;
- and
- wherein the composition comprises from about 10 mol % to about 70 mol % hydrogen.
