- Production of synthetic fuels through the pyrolysis of high density polyethylene (HDPE) waste was examined. A semibatch reactor was designed and fabricated to pyrolyse HDPE waste in the absence of catalyst at a residence time of 60 minutes and final temperature of 425oC. At the end of the process, 51.84%, 45.33%, and 2.83%, liquid product, char and evolved gaseous product were obtained respectively. The temperature progression for the process was examined. The pyrolysis oil obtained was light brown in colour, highly flammable, with a density of 772.6 kg/m3 and pH of 5.5. ASPEN Hysys was used to simulate the pyrolysis process. Simulation results revealed an oil yield of 97%, a gas yield of about 2% and a <1% char yield. The simulation revealed the commencement of reaction at about 325oC with an optimum reaction temperature of 450oC. If properly optimized HDPE is revealed to be an excellent feedstock of pyrolysis.
