Novel calcium based sorbent (Ca-C) for the dehalogenation (Br, Cl) process during halogenated mixed plastic (PP/PE/PS/PVC and HIPS-Br) pyrolysis

A calcium carbonate carbon composite sorbent (Ca-C) was prepared by using 90 wt% of calcium carbonate and 10 wt% phenol resin. The Ca-C sorbent was successfully utilised for the dechlorination and debromination process during halogenated (Cl, Br) mixed waste plastic (PP/PE/PS/PVC/HIPS-Br:3:3:2:1:1) pyrolysis at 430degreesC and produced halogen free liquid products.
