Abstract
A method of depolymerizing plastics using a fluorinated alumina catalyst is described herein. The method reduces the energy required for the depolymerization process while achieving improved depolymerization results.
Claims17
A method of depolymerizing plastics, comprising the steps of:
- introducing a reactant mixture into a reactor, the reactant mixture comprising a feedstock comprising plastic and a catalyst comprising a halogenated alumina;
- heating the reactant mixture so as to cause the plastic to depolymerize thereby forming a product.
The method of claim XX wherein the feedstock comprising plastic comprises at least 50 wt % of one or more of:
- HDPE, LLDPE, LDPE, PP, or mixtures thereof.
