Abstract

As we know, growing energy needs are not comparable with the growing availability of fuel thinning day. Therefore it is necessary for an investigation to obtain alternative source of renewable energy by utilizing animal waste such as animal fat. Utilization of beef fat potential when processed into a fuel because it can reduces the environmental impact caused by NOx emmision. In this research the fuel is made of beef tallow using a batch reactor. The aim of this research was to obtain liquid fuel in accordance Indonesian standard and determine the effect of catalyst variations and its amount. Liquid fuel was made through several stages of preparation such as raw materials, the catalysts, catalytic cracking and also final analysis,diesel product. The result of this research that the density obtained is 0,83 – 0,89 gr/ml, viscosity 2,72 – 4,92 cSt, and flash point 47,8 – 63,5 °C.

Abstract

According to data from the Kementerian Lingkungan Hidup dan Kehutanan (KLHK), the amount of waste in Indonesiain 2019 reached 68 million tons, and plastic waste is estimated at 9,52 million tons. Considering that the nature of plastic is difficult to decompose, it is necessary to handle environmentally friendly waste. One of the countermeasures for plastic waste is to convert it into liquid fuel through the pyrolysis process. The pyrolysis of LDPE plastic uses a catalytic cracking method with aluminium oxide and zeolite as catalyst. The independent variable of this study is the pyrolysis temperature variation. The temperature used are 150℃, 200℃, 250℃, 300℃, 350℃, 400℃, 450℃ and 500℃. The highest %yield using aluminium oxide was obtained at 350℃ is 8.34%, while higest %yield using zeolite was obtained at 500℃ is 10.5%.Based on the analysis conducted, it was found that the oil density using aluminium oxide was in the range746.66 kg/m3-815.61 kg/m3, when using zeolite oil density was in the range 0.72 gr/ml-0.758gr/ml. viscosity using aluminium oxide was in the range 2.143 mm2/s-2.730mm2/s and using zeolite was in the range 2.8893 cSt – 3.4589 cSt, flash point ranges from 26℃-32℃, calorific value using aluminium oxide using zeolite was 7587,1678 cal/gr and the results of pyrolysis oil using aluminium oxide and zeolite catalyst the GCMS analysis show that the highest percentage is the C8-C10 chain of 45.13% and 63%..
