“…Salah satu metode yang digunakan dalam pemurnian pelumas bekas adalah menggunakan asam kuat dan absorben. Absorben yang dapat digunakan untuk mengadsorpsi pengotor dalam minyak pelumas bekas adalah bentonite [5]. Bentonite memiliki kemampuan terbesar dalam proses pemurnian minyak pelumas bekas dibandingan dengan arang aktif dan zeolit [6].…”

Plastic to Solar (PLATOS) machine is a machine that processes plastic waste or used oil into fuel through a pyrolysis process. Based on observations made, pure diesel produced by the PLATOS machine has a very cloudy color or brownish black. Therefore, to get clearer fluid, a purification process is needed, one of which is by using bentonite powder. Bentonite powder used is Bleaching Earth Bentonite which can bind or absorb dirt and unwanted materials in oil or diesel, so that oil or diesel becomes paler and clearer. The heating method is used in the purification trial using a blow torch fire flame gun and an aluminum pan as a diesel fuel container. This study aims to observe the extent of the effect of using bentonite to improve the quality of diesel fuel that has been produced. The research was conducted by conducting 4 times the purification process with the same amount of bentonite and diesel weight of 20 grams and 1 liter. Based on the experiments that have been carried out, it can be concluded that the diesel produced has specifications that are within the limits of diesel specifications set by the Director General of Oil and Gas. Overall, the results of these specifications can state that the use of bentonite powder with heating methods up to 100o C can improve the quality of diesel fuel well.Keywords – Bentonite, Purification Process, Pyrolysis, Solar.

“…The results are presented in Table 3. Based on Table 3, the density and viscosity values of alternative fuels for each type of liquid product meets the standard commercial specifications for fuel oil according to the provisions of the Directorate General of Oil and Gas, Ministry of Energy and Mineral Resources of the Republic of Indonesia number 146.k/10/DJM/2020, so that the results of alternative fuel products with a bentonite catalyst weight fraction of 0.100 has quality that meets the requirements [24,25]. Furthermore, the alternative fuel products also have flash points (ASTM D7094) and provide consecutive flash point data: alternative gasoline 84 0 C, alternative kerosene 70 0 C, and alternative diesel 98°C.…”

The conversion is accomplished by pyrolyzing plastic bag waste at relatively low temperatures, around 50-225OC, and using a bentonite catalyst. The four products are alternative oils consisting of gasoline, kerosene, diesel, and non-condensable gas. The pyrolysis procedure is as follows: (a). 3 kg of chopped plastic waste mixed with a mass fraction of bentonite catalyst of around 0.035-0.0125 of the weight of plastic waste and then put into the pyrolysator; (b). the pyrolysator is heated with 1.5 kg of liquid petroleum gas (LPG) for 2-3 hours at a temperature ranging from 50-225oC; (c). pyrolysis results are stored separately in 3 pots: gasoline, kerosene, and diesel; (d). to clarify pyrolysis results by adsorption using a sand filter. The variables studied were the polypropylene (PP) and polyethylene (PE) plastic materials type and the effect of the mass fraction of bentonite catalyst ranging from 0.035 to 0.125. The research obtained relatively good results as follows. Pyrolysis of 3 kg of PP plastic waste with the mass fraction catalyst of 0.100 yielded 44.00% alternative gasoline, 10.76% alternative kerosene, 21.07% alternative diesel, and the remaining non-condensable gases. The flash (ASTM D7094) points of alternative gasoline, alternative kerosene, and alternative diesel are 84˚C, 68˚C, and 100˚C, respectively. The calorific value of each fuel product is 10,970 cal/g for alternative gasoline, 10,965 cal/g for alternative kerosene, and 10,816 cal/g for alternative diesel. In addition, the pyrolysis of PE plastic waste with the mass fraction of catalyt of 0.100 produced a yield of 27.65% for alternative gasoline, 17.11% for alternative kerosene, and 43.79% for alternative diesel, and the remaining was non-condensable gases. The respective flash points (ASTM D7094) of alternative gasoline, alternative kerosene, and alternative diesel are 84˚C, 70˚C, and 98˚C. The calorific values are alternative gasoline 10,979 cal/g, alternative kerosene 11,008 cal/g, and alternative diesel 11,027 cal/g.

Biodiesel can be made by utilizing used cooking oil through a chemical process, namely through a transesterification reaction, namely changing the oil (triglycerides) into fatty acid methyl esters. Washing must be done to remove the remaining impurities in biodiesel. The dry washing method is purification by utilizing the adsorption process to remove impurities in crude biodiesel. Bentonite is an alternative adsorbent that can be used as dry washing in the biodiesel refining process because it is cheaper, abundant in nature and has a layered structure with the ability to swell. The purpose of the study was to determine the ability of bentonite activated with acid as a dry washing agent in biodiesel purification. The research method used is the dry washing process method using bentonite adsorbents. The application of bentonite adsorbent as much as 6 grams with a contact time of 3 hours is the best operating condition to produce biodiesel with a pH of 6 and a clarity value of 96.7.
