“…93 Similar results can be seen in other studies. 48,146,147 Another less applicable metal in deoxygenation is Sn which commonly used in the form of bimetal catalyst. The sole Sn metal displayed low to moderate conversion and selectivity causing the role of Sn as the promotor metal.…”

“…In addition, the price is also low compared to new oil. Rashidi et al (2022) found that the fatty acids that make up waste cooking oil consist of meristic acid (1.1%), palmitic acid (35.7%), palmitoleic acid (2.7%), stearic acid (4.8%), oleic acid (41.6%), linoleic acid (13.5%), and linolenic acid (0.6%). This condition provides an opportunity to develop palm oil and its derivatives as feedstock for green diesel.…”

Petroleum is the primary energy that is generally used throughout the world. Its non-renewable nature and exhaust gas emissions that can damage the environment are a concern for developing environmentally friendly renewable energy. Green diesel is an alternative energy to replace diesel fuel (diesel) from petroleum which has the potential to be developed. The raw material in palm oil has great potential for development due to its relatively high production. Green diesel synthesis can be carried out using the catalytic deoxygenation method. The type of raw material, catalyst, and process conditions influences this method. The catalyst is the most influential factor in catalytic deoxygenation. Transition metal catalysts like nickel are inexpensive and have good catalytic activity like precious metals. Catalytic activity can be increased by modifying the catalyst components and optimizing the process. Modification of the catalyst can increase the surface area, Lewis and Bronsted sites, and crystal size so that the resulting green diesel can be maximized, such as Ni-Co, Ni-Zn, and Ni-Mo bimetallic catalysts.

“…The same research group also reported hydrogen-free catalytic deoxygenation of waste cooking oil over various bimetallic catalyst-supported on SBA-15. The results showed Ni-Fe/SBA-15 exhibited the highest yield of liquid hydrocarbons (Rashidi et al,2022).…”

The conversion of fatty acids into bio-hydrocarbons can be carried out through a deoxygenation (DO) reaction. Catalytic deoxygenation of fatty acids can occur through three reaction pathways: decarbonylation, decarboxylation, and hydrodeoxygenation. In this study, three kinds of silica were prepared: (i) silica obtained from the rice husk ash (RHA); (ii) synthetic mesoporous silica SBA-16; and (iii) commercial silica. All prepared silica was used as supported nickel (Ni) catalyst for bio-hydrocarbon production through DO reaction of oleic acid. The objective of this study was to investigate the effect of variations of silica on the reaction pathway and final products composition of DO reaction of oleic acid. The catalysts were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), surface area analysis, and NH3-temperature-programme desorption. Based on XRF and XRD analysis results, it can be concluded that nickel was successfully impregnated into all silica. All samples of catalysts were used in a reaction carried out at temperature of 285 °C under a pressure of 40 bar H2 for 2h. The results showed that all catalysts were able to convert oleic acid to bio-hydrocarbon with differences in products composition. The highest oleic acid conversion of 98.25% was achieved with Ni/RHA catalyst but the obtained liquid products was the lowest among other catalysts. It is found that this phenomenon was closely related to the acidity properties of the catalyst.
