Catalytic Pyrolysis of Polypropylene to Benzene, Toluene, and Xylene (BTX) Using a Double-Fluidized-Bed Reactor.

The current plastic value chain is highly linear, leading to large amounts of waste plastics that harm the environment and human health. Recycling is required, and among the options, catalytic pyrolysis is particularly suited to convert polyolefin-rich plastic waste into useful chemicals such as benzene, toluene, and xylene (BTX). In this paper, we demonstrate catalytic pyrolysis of polypropylene in a continuous double-fluidized-bed reactor to produce BTX.
