“…The transesterification reaction is made up of three consecutive reversible reactions, as indicated in Equations (3) to (5). Methanol was used in excess of the required quantity, the equilibrium reaction shifted to biodiesel production, and the overall transesterification reaction was written as Equation (6).…”

“…One of the green energies is biodiesel, 3 an alkyl ester, which is a suitable substitute for diesel 4,5 . Biodiesel is a renewable fuel, biodegradable, environmentally friendly, and usable in a diesel engine without any alterations 6 . Due to the presence of oxygen in the biodiesel structure, it burns better than diesel.…”

The transesterification of waste oils to biodiesel was carried out in the presence and absence of ultrasound. A new nanocatalyst of the calcium-strontium oxide was applied with high catalytic activity. The innovation of this work is an environmentally friendly synthesized nanocatalyst with ultrasound at low temperatures. After synthesis, the nanocatalyst was characterized with FESEM, FT-IR, and CO 2 -TPD, NH 3 -TPD. It was mesoporous and showed great basicity by the CO 2 -TPD method. The highest conversion of biodiesel was 99.2% under optimal reaction conditions (2.5 wt% nanocatalyst, oil to methanol molar ratio 1:6, time 40 minutes, temperature 35 C, and 42% amplitude of ultrasound).

“…As a product of the reaction, biodiesel is obtained, which has to be purified for later use as a biofuel. In addition, the transesterification reaction gives rise to other products, such as fatty acids or glycerin, which are used in the food industry and in the cosmetic industry [ 20 , 24 , 25 ].…”

Hydrothermal Liquefaction of Biomass as One of the Most Promising Alternatives for the Synthesis of Advanced Liquid Biofuels: A Review

et al. 2021

The use of biofuels offers advantages over existing fuels because they come from renewable sources, they are biodegradable, their storage and transport are safer, and their emissions into the atmosphere are lower. Biomass is one of the most promising sustainable energy sources with a wide variety of organic materials as raw material. Chemical, biochemical, and thermochemical methods have been proposed to obtain biofuels from raw materials from biomass. In recent years, a thermochemical method that has generated great interest is hydrothermal liquefaction. In this paper, a brief review of the main sources for liquid biofuels and the synthesis processes is presented, with special emphasis on the production of biofuels using hydrothermal liquefaction by using waste generated by human activity as raw material.

“…Sustainable sources of energy should be researched and used to minimize the general dependence on open primary sources of energy, i.e., fossil fuels 2. Biodiesel appears to be a viable alternative in this context which reduces the emissions of complete non‐combusted hydrocarbons by more than 90 % 3. An outstanding review describing multiple sources of vegetable oil feedstock used to produce biodiesel has been presented by Leung et al 4.…”

Data-driven modeling of biodiesel production was developed by simultaneous transesterification and esterification of rapeseed oil and myristic acid with methanol, without catalyst or with different amounts of sulfated zirconia catalyst. An artificial neural network (ANN)-based model was created with experimental literature data. The input data, i.e., reaction time, catalyst, temperature, and methanol-to-oil ratio, and output data, i.e., total fatty acid methyl ester and oleic acid methyl ester, were considered to develop the model. Multiple input single output (MISO) ANN architecture was taken to predict the above targeted two output parameters. The proposed ANN model is computationally efficient and works reasonably well when tested on biodiesel production for solving the MISO model.
