Catalytic Cracking of Waste Plastics Without Residue

2 CATALYTIC CRACKING OF WASTE PLASTICS WITHOUT RESIDUE 

The catalytic cracking of PET was carried out using a fixed-bed type of reactor in a steam atmosphere. The reactor was heated to the desired temperature in a mixture of 

Terephthalic acid is a useful source material of PET, as well as benzoic acid and benzoates. However, in order to recycle the terephthalic acid, produced further purification is required, because other organic compounds are also produced as impurities in the degradation process of waste plastic mixtures, e.g. PE and PET mixtures described in Section 2.3.
