“…Figure 3 reveals that with the increase in the weight fraction of the bentonite catalyst from 0.035 to 0.100, the non-condensable gas yield will also decrease from 25.88% to its lowest point at 11.45%, whereas with the increase in the weight fraction of the bentonite catalyst from 0.100 to 0.125, then the yield of noncondensable gases will increase from 11.45% to around 21.09%. This shows that the bentonite catalyst plays a role in conditioning and directing the pyrolysis product phase to the liquid phase [22,23]. Optimization is based on the highest sales results from alternative gasoline, alternative kerosene, and diesel products.…”

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.

Liquid fuels resulting from catalytic cracking by Kar et al achieved 98.64% of yield with 4% of the catalyst [37]. In the transesterification process, bentonite removes water and increases the methanolysis process.…”

Oil palm empty fruit bunch (OPEFB is one of the enormous waste expected to become a renewable energy source. This study aimed to convert OPEFB into syngas through a gasification process using bentonite as a catalyst. The effects of temperature and product gas catalysts were investigated, and the efficiency of the gasification process was summarized. The process has used an updraft gasifier at 350-550 °C and air as the gasification medium (ER 0.2). The results indicate that syngas can be produced by updraft gasifier. When the temperature increase, the H2 and CO rising. The highest H2 and CO content of 27.74% and 20.43% are obtained at 550°C when bentonite applied. HHV and LHV range of 3.38~12.79 MJ/Nm3 and 3.03~11.58 MJ/Nm3, respectively. The maximum carbon conversion efficiency (CCE) and cold gas efficiency (CGE) reach 85.49% and 82.34%. Bentonite has been able to increase the concentration of the gas composition especially H2 and CO and the heating value of syngas.

“…Natural and chemical-modified bentonite is used directly or as an industrial feedstock in many areas, depending on its physicochemical properties (Hasanudin et al, 2022;Kar et al, 2019;Komadel, 2016). Al/Fe-pillared bentonite was characterized using XRD, as shown in Figure 6.…”

Modification of bentonite by the Al/Fe metal oxide pillarization process was carried out with metal oxides. The bentonite pillars were successfully characterized using an X-Ray Diffraction (XRD) spectrophotometer. The results of XRD characterization showed the peak diffraction angle (2θ) in metal-pillared bentonite was 26.84° at 698.98 cps. Meanwhile, in thermally and chemically activated bentonite, the peak angles were marked at 20.64° and 26.7°. There is a shift in the peak angle after activation and pillarization. XRD patterns showed dioctahedral smectite and quartz accessory minerals.
