The growing demand for energy resources and the increase in greenhouse gas (GHG) emissions has given biofuels a lot of attention. Liquid biofuels can be a significant alternative for the transport sector. Generally, biofuels are categorized into four generations based on the feedstock. This review reports the availability, economic feasibility, and potential of biofuel feedstock in global scenario. Feedstock for first-generation biofuel comprises edible resources impacting the food supply. Second generation biofuels are based on different residual materials and nonedible fuel crops. Cost and technological limita-tions for commercialization hinders this option. Microalgae are the feedstock for third generation biofuels providing the highest yield compared to the other two generations. A scale-up to commercial level is not possible as this requires further development. Genetically modified microorganisms are used as a feedstock for fourth generation biofuel production with the highest possible yield. Third and fourth generation biofuels have potential to replace fossil fuels. This review recommends certain suggestions for sustainable biofuel production.

“…FCCD was applied in this study to explore not only the individual effect of process parameters on biodiesel yield, but also their interactive effects on the response. Three variables, ethanol-oil molar ratio (x 1 ), catalyst concentration (x 2 ) and stirring speed (x 3 ) selected on the basis of related literature research and preliminary experiments in our laboratory [34][35][36][37][38], were considered as independent variables affecting the conversion rate of WCO to biodiesel. The response selected was the yield of ethyl ester (Y%).…”

Biodiesel production from Waste Cooking Oil (WCO) is the most suitable diesel fuel substitute, due to its cleaner emissions, engine lubricity, nontoxic properties, and renewable sources. This study mainly focused on improving biodiesel experimental production using ethanol and investigating the influence of main operating parameters (ethanol–oil molar ratio, catalyst concentration and stirring speed) on biodiesel yield using Response Surface Methodology (RSM). The problem with using ethanol at the expense of the toxicity of methanol as an alcohol is mainly the separation of glycerol from biodiesel at the end of the transesterification reaction. However, the addition of 5% (v/v) glycerol and 1% (v/v) water at the end of the reaction has been found to aid this separation and improve oil conversion. The optimization of the produced biodiesel is carried out through three factors: Face-Centered-Composite Design (FCCD), building a mathematical model, and statistical analysis, shows that the experimental results agree with the predicted values; they are close to unity with the R2 value (0.9924), indicating the correctness of the model. The optimal conditions of catalyst concentration (1.62 wt%), stirring speed (200 rpm) and molar ratio of ethanol to oil (12.9:1) were obtained, resulting in a biodiesel efficiency of 89.75%. The model was also experimentally validated, achieving about 90% biodiesel yield. The fuel properties of the ethyl ester were investigated and compared successfully with the EN and ASTM standards and with baseline local diesel (NA 8110).

“…Due to the increasing in energy demand and the pollution problems caused by the use of fossil fuels, the used of vegetable oils and their derivatives as alternative for biodiesel is the best solution in current situation (Lawan and Serder, 2019). Production of biodiesel is a recent area for researchers and has a positive impacts (Ahmia et al, 2014). Alumina is an important industrial mineral, which can be used as catalyst, abrasive and as adsorbent (Salahudeen et al, 2015).…”

Biodiesel was produced from the transesterification of neem oil with methanol using alumina catalyst. The transesterification was carried out under the optimal condition of methanol to oil molar ratio of 6:1. The reaction for the production of biodiesel using alumina catalyst conforms to a pseudo – first order rate law with reaction rate constants of 0.0028, 0.0044, and 0.009 min-1 at 308, 318, and 328 K, respectively. Activation energy for the reaction was 48.45 kJmol-1 and pre – exponential factor (A) of 13.003. The thermodynamics parameters for the reaction was calculated as 46.02 kJmol-1 and -0.1449 kJmol-1 for enthalpy and entropy respectively. The Gibbs free energy was calculated to be 90.68, 92.13, and 93.58 kJ mol-1 at 308, 318, and 328 K, respectively. In this research, kinetics and thermodynamics study of biodiesel production from neem oil was carried out. This shows that kinetics study was carried out to determine the rate constants of the reaction, the reaction rate constants also increases concerning the temperature of the reaction. The thermodynamics study was carried out, the positive value of H, negative S and positive G indicate this reaction is endothermic and non – spontaneous.
