Current petroleum energy sources have been starting to diminish along with the increasing a demand in industries and transportations. In the next few years Indonesia is predicted to experience a fuel crisis. One way to solve this problem is to find the alternative energy sources from renewable raw materials. This study was conducted to obtain alternative renewable energy sources through catalytic cracking of used cooking oil-derived methyl ester into biofuel using active charcoal catalyst. The active charcoal was made out of solid waste (shells) of the oil palm industry. Nickel solutions of varying concentrations (1%, 2%, 3%) ware impregnated into active charcoal to produce the Ni- charcoal catalyst. This catalyst was then used for catalytic cracking of methyl esters with variations in the reaction temperature of 400oC, 450oC and 500oC. The Methyl ester was produced from filtered used-cooking oil by transesterification method. SEM-EDX analysis showed that Nickel metal was successfully embedded into active charcoal where the highest concentration of Nickel (18.4%) was found at a impregnation treatment using 2% of Nickel solution. From the SEM image, it can also be seen that the catalyst produced unique pores. The gravimetric analysis of the catalytic cracking product showed that the highest fraction of oil liquid resulting from catalytic cracking at 400oC using Ni-charcoal catalyst impregnated with 3% Nickel solution.

“…Pyrolysis is the one solution to recycle waste materials like used cooking and lubricant oil into useful material such as fuel (Alfernando, Sarip, Anggraini, Nazarudin, 2019;Prabasari, Sarip, Rahmayani, Nazarudin, 2019;Fitriyanti, 2020), reduced sulphur content of fuel (Bhaskar, Uddin, Muto, Sakata, Omura, Kimura, Kawakami, 2004), surfactants (Sharma, Toor, Brandão, Pedersen, Rosendahl, 2021), plastisizer (Cai, Yue, Hao, & Ma, 2020), and etc. At this method, waste material is heated at a high temperature and then break into new material.…”

“…At this method, waste material is heated at a high temperature and then break into new material. Pyrolysis can be carried out using catalyst (Alfernando et al, 2019;Prabasari et al, 2019;Fitriyanti, 2020) or without catalyst (Ayodeji and Oni, 2018;Alfernando, Nugraha, Prabasari, Haviz, Nazarudin, 2020). Due to a quite expensive catalyst, thermal cracking is more preferred despites its limitation in selectivity (Gaur, Mishra, Chowdhury, Baredar, Verma, 2020).…”

Pyrolysis is the one solution to recycle hydrocarbon-based waste material such as used lubricant and cooking oil. The aim of this research was to determine the effect of temperature and sample ratio on the liquid yields of a mixture of used lubricant and cooking oil. The semibatch reactor was used with a constant nitrogen flow rate of 5 mL/min. Three different ratios of sample mixture were applied in this experiment: 0.5:1, 1:1, and 1.5:1, and three different temperatures: 4000C, 4500C, and 5000C. The thermal pyrolysis of a mixture of used lubricant and cooking oil was deemed as the most effective pyrolysis to produce liquid fraction was obtained from reaction condition with the sample mixture ratio of 0.5:1 at 5000C. At this reaction condition, the liquid yields was 58.90% which consist of 64.12% were C1-C3 and 29.54% were C5-C15. Liquid fraction is predicted to increase as the temperature increase and the ratio of used lubricant to cooking oil decrease. When the ratio is increased , more gas fraction is produced.

One of the solutions for fossil fuel crisis is to find alternative energy based on renewable materials. In this research, catalytic cracking of used cooking oil has been investigated to produce biofuel using Cr-charcoal catalyst. The charcoal was produced from solid waste (shell) of palm oil industry. Chromium solutions with various concentrations (1%, 2%, and 3%) were impregnated into charcoal to produce Cr-charcoal catalyst. The catalysts were used for catalytic cracking of used cooking oil at three levels of temperature: 450°C, 500°C and 550°C. The XRD patterns and SEM images of the catalyst showed that the catalyst was in amorphous form. SEM-EDX analysis showed that the Chromium was impregnated into charcoal successfully with amount of Chromium absorbed into charcoal was 0.51%; 1.07% and 14.38% respectively. The SEM images also showed that charcoal as supported catalyst and Cr-charcoal catalyst have unique pores. The highest liquid oil fraction was obtained by catalytic cracking at 500°C using 3% Cr-Charcoal catalyst. The liquid product of this process was mainly diesel oil with 8-24 carbon atoms (86.35%) and the rest was liquid product with 6-7 carbon atoms.
