“…Similar results were reported by Santos et al (2009). The highest biodiesel yield was accomplished when 9:1 alcohol to oil ratio was used (Santos et al, 2009). In a recent study, Shiu et al (2010) used two-step in-situ transesterification with acid catalyst treatment followed by a base catalyst to produce biodiesel from rice bran.…”

“…They showed that ultrasonication had a positive effect on transesterification process and reduced the process time and saved energy in the biodiesel production (Stavarache et al, 2005). Santos et al (2009) studied the effect of ultrasonication during the process of biodiesel production from soybean oil. They used methanol and KOH as a catalyst.…”

“…It is clear to see that this technique is effective in providing mixing and activation energy, as the application of ultrasonic energy to biodiesel production increases the yield, up to 99%, in few minutes [16]. Several authors have reported on the effectiveness of power ultrasound and have suggested a host of advantages which include shorter reaction times, improved mass transfer, reduced costs and energy consumption over mechanical agitators [28][29][30][31]. In recent years, researchers have widely used microwaves in biodiesel production because of its unique acceleration, lower alcohol to oil ratio and effectively-reduced byproduct amounts [32][33][34][35][36][37][38].…”

This work investigates the effect of simultaneous ultrasound-microwave irradiation on palm oil transesterification and uncovers optimal operating conditions. Response surface methodology (RSM) has been used to analyze the influence of reaction conditions, including methanol/palm oil molar ratio, catalyst concentration, reaction temperature and irradiation time on biodiesel yield. RSM analyses indicate 136 s and 129 s as the optimal sonication and microwave irradiation times, respectively. Optimized parameters for full conversion (97.53%) are 1.09% catalyst concentration and a 7:3.1 methanol/ oil molar ratio at 58.4°C. Simultaneous ultrasound-microwave irradiation dramatically accelerates the palm oil transesterification reaction. Pure biodiesel was obtained after only 2.2 min while the conventional method requires about 1 h.

To date, the majority of world's primary energy is derived from fossil fuels. However, the fossil fuel recourses are in an inevitable decline as energy demand continues to grow exponentially with population growth, urbanization, and improved standards of living. Crude oil prices have recently risen several times and their current annual volatility exceeds 30%. The potential scarcity of fossil fuels has prompted a global search for alternative energy resources. Biodiesel fulfills the major requirements for production of alternative fuels such as feedstock availability, technical feasibility, and economic competitiveness. Together with other renewable biofuels, the use of biodiesel as a substitute of fossil‐based fuels is expected to reduce the dependence on imported petroleum and associated political and economic vulnerability, decrease greenhouse gas emissions, and revitalize the economy. The objective of this article was to provide an update of the most recent technological advancements toward clean and sustainable biodiesel production through a thorough overview of biodiesel feedstocks, most promising transesterification processes, and opportunities for glycerol utilization for value‐added products. A critical analysis of the techno‐economical barriers and environmental challenges that need to be addressed in future R&D efforts toward commercialization and establishment of a sustainable and cost‐efficient biodiesel production is provided.
