Tested an iron oxide-carbon composite catalyst for the selective vapour phase dechlorination of chloroalkanes. 4. Dehalogenation in the presence of antimony, studied by Uddin et al. 5. Closing the bromine cycle, with initiatives of the European Brominated Flame Retardant Industry Panel (EBFRIP) in cooperation with the Bromine Science and Environmental Forum (BSEF), including a study prepared by ECN (Petten) on a two-stage pyrolysis/high-temperature gasification process. 3 COLLECTION SYSTEMS Under pressure from legislation, in particular the Packaging and Packaging Waste Directive, 94/62/EC, recycling of packaging products has increased dramatically from 1995.

In the Janaf Tables [19]. 3 Kinetics and Mechanism of Pyrolysis The study of kinetics and mechanism of pyrolysis is of considerable scientific interest, with regard to the thermal behaviour of organic molecules, the precise constitution of molecules or copolymers, including irregularities, such as structural defects and incorporation of initiator molecules and radical scavengers, used to control the MW. 8. The kinetic parameters given are derived from the thermogravimetric experiments. The mechanisms of pyrolysis, as discussed by this team, are too complex and varied to be treated here in more detail.

PMMA or PA 6. For bulk polymers, such as polyolefins, polystyrene, polyesters, and PVC the scale of production is too small and the margins too low to make plastics pyrolysis an economically viable process. The presence of additives, soil, or other resins, incorporating hetero-atoms, leads to both operating and product specification problems, rendering pyrolysis generally economically unviable. Another important factor is securing an adequate dump fee, to sustain the operation financially, as well as the availability of raw materials, a problem of finding sources, optimizing logistic factors (plastics are light and bulky), sorting, cleaning and handling, and ensuring steady specifications.
