“…The main reason of the difference is certainly due to the high experimental conversion. Nevertheless, a quasi-equimolar formation of 1-alkenes is found in several carbon atom ranges, such as between C 10 -C 13 , C 14 -C 17 , C 18 -C 21 , C 22 -C 28 [16]. As an example the section of the pyrolysis-gas chromatogram displaying the product distribution of C 18 -C 22 hydrocarbons obtained at 500 8C in a micropyrolyser (see Section 3) is shown in Fig.…”

“…They used pyrolysis-GC/MS to investigate the decomposition of pure TBBPA. Blazso [8] investigated the pyrolysis of brominated epoxy resin using pyrolysis-GC/MS and reported reduced concentrations of brominated compounds when Zeolite was present in the pyrolysis process. In an earlier study, Blazso et al [9] used pyrolysis-GC/MS to investigate the pyrolysis of flame retarded printed circuit boards and phthalic polyester that was flame retarded with brominated polystyrene, they reported decreased concentrations of organobromines during the pyrolysis of both plastics in the presence of Zeolites.…”

Two flame retarded plastics have been pyrolysed in the presence of two Zeolite catalysts to remove the organobromine compounds from the derived pyrolysis oil. The flame retarded plastics were, acrylonitrile -butadiene -styrene (ABS) that was flame retarded with tetrabromobisphenol A and high-impact-polystyrene (HIPS) that was flame retarded with decabromodiphenyl ether. The two catalysts investigated were Zeolite ZSM-5 and Y-Zeolite. Pyrolysis was carried out in a fixed bed reactor at a final pyrolysis temperature of 440 ºC. The pyrolysis gases were passed immediately to a fixed bed of the catalyst bed. It was found that the presence of Zeolite catalysts increased the amount of gaseous hydrocarbons produced during pyrolysis but decreased the amount of pyrolysis oil produced. In addition, significant quantities of coke were formed on the surface of the catalysts during pyrolysis. The Zeolite catalysts were found to reduce the formation of some valuable pyrolysis products such as styrene and cumene, but other products such as naphthalene were formed instead. The Zeolite catalysts, especially Y-Zeolite, were found to be very effective at removing volatile organobromine compounds. However, they were less effective at removing antimony bromide from the volatile pyrolysis products, although some antimony bromide was found on the surfaces of the spent catalysts.
