The catalytic upgrading of the pyrolysis gases obtained from the pyrolysis of PE was investigated by Bagri and Williams [74] in a fixed bed reactor using a Y-zeolite catalyst. The results showed that a liquid oil yield of 95 wt% was obtained in the absence of a catalyst, with very little or no char, and a very low gas yield at 500°C.
