Abstract

Increasing amount of plastic waste has become main concern to the environment. Since plastic waste is non-biodegradable and takes millions of years to be decomposed. Therefore proper solutions need to be found such as by using pyrolysis process that can produce liquid fuel oil. And in order to obtain more yield of the fuel oil, catalyst of active carbon and activated bentonite clay was used in this research. The activation of bentonite clay was done physically at 700°C for 6 hours. And the fuel oil analysis includes observation on yield, density, viscosity, flashpoint, heating value and FTIR. It can be conclude that increasing the temperature and using catalyst in pyrolysis can increase the yield of fuel oil produced. And the most effective catalyst mass ratio of active carbon and activated bentonite clay are 30:70 at temperature of 350°C, which yielded 69.74%. Higher amount of activated bentonite is more effective than active carbon as catalyst. From the fuel oil analysis the average density of pyrolysis fuel oil is 0.7807 kg/L and the kinematic viscosity is 1.0cst, which density and kinematic viscosity is in between of kerosene and gasoline. The flash point of fuel oil was ranging from 9.15-28.15°C, which is closest to Ethyl Alcohol 70%. Calorific result of fuel oil using catalyst and non-catalyst show that the are a slight increase in calorific value of pyrolysis oil when added with catalyst with mass ratio of catalyst 30:70 at 350°C which are, 45.722141 MJ/kg and lower calorific value of 45.722141 MJ/kg on temperature 350°C with non-catalyst. This demonstrates that the various amount of catalyst ratio influence the calorific value. The calorific value of pyrolysis oil is almost equal to the diesel oil heating value of 44.8 MJ / kg. Based on FTIR analysis results it is known that the largest component of liquid fuel product contains alkane and alkene. Comparison between spectrum of FTIR result without catalyst, with spectrum of FTIR result with catalyst of 30:70, it is seen that there is a change in the reduction of stronger absorption peaks and forming a simpler new bond as it can be seen that there is a significant increase of peak intensity in wavenumber (886.75 cm -1) after using catalyst. Wavenumber 1456.02 cm -1 and 886.75 -1cm show the formation of aromatic compound of C=C and C-H which are similar to the structure of benzene in gasoline.
