Abstract

The number of passenger automobiles, buses, cargo cars, and motorcyclists on the road in Indonesia continues to rise year after year. According to the Central Statistics Agency, the number of transportation equipment in 2015 was 105,303,318 million, up 6.5 percent from the previous year. In 2016, it was 112,205.711 million, up 6.5 percent. As can be seen from the above, Indonesia's transportation options are expanding throughout time. As a result, the demand for lubricants rises as well. As the need for lubricants grows, so does the amount of spent lubricants that is thrown away. Water absorption is inhibited by used lubricant waste that is disposed of in the soil. Given the aforementioned issues, a solution for converting spent lubricant waste into something more useful, such as liquid fuel, is required. Making a prototype for turning spent SAE 5W-30 lubricant waste into liquid fuel using the hydrocracking method with the help of a Ni/ZAA catalyst is one approach to go about it. The effect of temperature fluctuations of 300 °C, 350 °C, 400 °C, 450 °C, and 500 °C was employed as the independent variable in this investigation. The amount of used lubricant feed used in this investigation is 641.10 ml, which is a fixed variable. The best yield values were obtained at a temperature of 400 °C with a cetane number of 76.2, which met the diesel requirement.

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.
