Abstract
A method of recycling a plastic includes decomposing the plastic in the presence of a catalyst to form hydrocarbons. The catalyst includes a porous support having an exterior surface and defining at least one pore therein. The catalyst also includes a depolymerization catalyst component disposed on the exterior surface of the porous support for depolymerizing the plastic. The depolymerization catalyst component includes a Ziegler-Natta catalyst, a Group IIA oxide catalyst, or a combination thereof. The catalyst further includes a reducing catalyst component disposed in the at least one pore.
