Abstract
Pyrolysis is taken into account as the foremost promising thermochemical conversion technology for converting solid wastes into liquid fuels. The present work focused on producing liquid from PET plastic fuel with catalyst employment through the pyrolysis process. Moreover, it aims to differentiate quantitively and qualitatively the liquid yield's improvement concerning the catalyst employed in its benzoic acid content, high heating value, density, and fire and flashpoint. The product yields and compositions are also determined. The experiment takes place in a batch reactor with a heating range of 350–500 °C. The process that used Ca(OH)2 as a catalyst encompasses a maximum liquid yield of 70.6%. In terms of density, the oil produced from three catalysts’ employment has comparable value with the commercial light petroleum fuel in a range of 794–884 kg/m3. The pyrolysis with the Fe2O3 catalyst has the lowest flashpoint of 28.2 °C, while the zeolite and Ca(OH)2 catalytic process has the same flash point of 30 °C. Also, the Fe2O3 catalytic process has the highest fire point of 40.6 °C among the three catalysts. The pyrolysis with Ca(OH)2 catalyst had a maximum heating value of 9284.05 cal/g when Ca(OH)2 was used as a catalyst. The paper concludes with the addition of catalyst, namely zeolite, Ca(OH)2, and Fe2O3, into PET plastic in the pyrolysis process, increased oil yields, and improved its characteristics.
