The catalytic decomposition of mixed plastics consisting of polypropylene (PP) and polyethylene terephthalate (PET) has been
investigated over titania/silica catalysts at 698 K. The yield of oil produced was about 70%, and the large amounts of C18+ hydrocarbons this contained was from the aromatics in PET. Gas was also produced, including C3–C5 hydrocarbons. The carbon-number fractions in the oil was influenced by the PET/(PP + PET) ratios and the catalyst weight.
The titania/silica catalysts could be used repeatedly, and after they had been fouled, could be regenerated. From the Fourier
Transform Infrared (FT–IR) spectroscopic data of adsorbed pyridine on the catalyst surface, most of the acid sites of the
titania/silica catalysts were found to be Lewis sites where the hydride abstracted from PP pyrolysates react with PET pyrolysates
to form oil and gas.
