“…8 Shah et al also found that liquid product yields were in the range 62-79% when using ZnO, MgO, CaC 2 , SiO 2 , Al 2 O 3 and SiO 2 -Al 2 O 3 as catalysts in pyrolysis of LDPE. 4 The system in this current work can obtain high liquid product with small amount of catalyst (catalyst to plastic waste ratio of 0.05) and at short reaction times (10 min). For example, optimum conditions for pyrolysis of HDPE with CaCO 3 are catalyst ratio of 0.2 and reaction time of 1.5 h. 5 Panda and Singh also used catalyst ratio of 0.33 with reaction time of 75 min to received highest yield of liquid product around 89.5 wt% by pyrolysis of PP with kaoline.…”

“…3 Over the past two decades, a large number of results on catalytic pyrolysis process for plastic have been reported. [4][5][6][7][8][9][10][11][12][13][14] A wide range of catalysts such as ZnO, 4 MgO, 4 CaCO 3 , 5 CaC 2 , 4 SiO 2 , 4 Al 2 O 3 , 4 SiO 2 -Al 2 O 3 , 4 ZSM-5 zeolite, 6-8 kaolin, 9,10 red mud, 8,11 CuCO 3 , 12 and FCC, 13,14 have been used. The present study attempts to utilise bentonite clay as an inexpensive and widely abundant material as a catalyst in the pyrolysis of waste plastic.…”

“…Other researchers have used catalysts to similar types of batch reactor setups to improve the evolution of hydrocarbon yields. However, high coke normally results in such setups due to the possibility of reaching elevated temperatures in such a reactor system Adrados et al, 2012;Shah et al, 2010;Abbas-Abadi et al, 2014). Vasile et al (2006) used a batch reactor to pyrolyse various waste from electrical and electronic equipment (WEEE) reaching pyrolysis oil yield of over 70 wt%.…”
