Pyrolysis process is the thermochemical decomposition of organic compounds such as High-density polyethylene (HDPE) plastic. The main product of HDPE pyrolysis is usually diesel, but there are some other waste products formed (e.g. carbon black). Pyrolysis reactions are essentially decomposition reactions performed at elevated temperatures in the absence of oxygen. There is a variety of complex reactions taking place during pyrolysis, but in this paper, the focus is on the three main reactions of HDPE pyrolysis, namely: beta−scission, hydrogen abstraction and chain fission. Of these, beta−scission is known to be the most dominant reaction in HDPE pyrolysis reactions. In this work, the reaction equations and reaction constants were defined and solved in MATLAB®using the in-built ordinary differential equation (ODE) solver. The solution represents the rate of the reaction and the product yield.References
