Chemical Recycling of Polyolefinic Waste to Light Olefins by Catalytic Pyrolysis
Catalytic pyrolysis of post‐industrial and post‐consumer waste is studied in an auger‐type reactor at pilot scale by applying two different zeolites and an amorphous silica‐alumina catalyst in‐situ at 400–550 °C. Contrary to thermal pyrolysis, of polyolefin‐rich waste, high gaseous pyrolysis product yields of approx. 85 wt % are achieved with C2–C4 olefin contents of up to 67 wt %. After deactivation by coke deposition catalyst regeneration is proved feasible for maintaining the gaseous product yield and composition. Waste feedstocks with significant nitrogen and halogen heteroatom content are not suitable for in‐situ catalytic pyrolysis.
