“…There are natural and synthetic catalysts, where the former is obviously cheaper than the latter. A research using PE and PS proved that if the optimum temperature for thermal cracking was 410 o C -430 o C, lower temperature, around 390 o C, could be used for catalytic cracking [3]. Lee conducted investigation without and with catalyst, called FCC (fluid catalytic cracking) catalyst.…”

“…From the study of HDPE pyrolysis in a fluidized sand bed reactor, they have found that the yield of total gas obtained increased in the range 500°C -800°C from 5.7 to 94.5%, at higher temperatures. Walendziewski et al (2001) reported the thermal degradation of polyethylene in the temperature range 370-450°C. In the case of thermal degradation of polyethylene, an increase in degradation temperature led to an increase of gas and liquid products, but a decrease of residue (boiling point >360°C).…”

-Thermal degradation of waste plastics in an inert atmosphere has been regarded as a productive method, because this process can convert waste plastics into hydrocarbons that can be used either as fuels or as a source of chemicals. In this work, waste high-density polyethylene (HDPE) plastic was chosen as the material for pyrolysis. A simple pyrolysis reactor system has been used to pyrolyse waste HDPE with the objective of optimizing the liquid product yield at a temperature range of 400ºC to 550ºC. Results of pyrolysis experiments showed that, at a temperature of 450ºC and below, the major product of the pyrolysis was oily liquid which became a viscous liquid or waxy solid at temperatures above 475ºC. The yield of the liquid fraction obtained increased with the residence time for waste HDPE. The liquid fractions obtained were analyzed for composition using FTIR and GC-MS. The physical properties of the pyrolytic oil show the presence of a mixture of different fuel fractions such as gasoline, kerosene and diesel in the oil.

“…(Aguado and Serrano 1999;Fukushima et al 2009). Variety of suitable catalysts can be selected according to the desired product quality (Walendziewski and Steininger 2001). The catalytic pyrolysis of waste high-density polyethylene over modified zeolites was found to be a promising plastic waste recycle method to produce petroleum fuel-like products (Zeaiter 2014).…”
