H-Gallosilicate-Catalyzed Degradation of Polyethylene into Aromatic Hydrocarbons Using Different Types of Reactors

A fixed-bed flow reactor, in which melted polyethylene came into contact with H-gallosilicate catalyst, was highly effective in converting the polymer to aromatic hydrocarbons. The yield of aromatics was much lower when the degradation was performed by heating a mixture of the polymer and the catalyst in a batch reactor.
