“…3,4 However, the high free fatty acid (FFA) content of low-cost feedstocks may be a major hindrance to biodiesel production because of the use of dominant industrial basic catalysts. [5][6][7] The higher FFA content of feedstock is known to reduce biodiesel yield significantly when using alkaline catalysis technology, because of the consumption of catalyst and difficulties involved in separating and purifying the product. 8 Therefore, a two-step pretreatment process for the removal of FFAs by acid esterification, and the subsequent base transesterification to biodiesel are typically used to convert such oils to biosiesel.…”

A long-chain Brønsted acid ionic liquid (IL), 3-(N,N-dimethyldodecylammonium)propanesulfonic acid p-toluenesulfonate ([DDPA][Tos]), was prepared and characterized by FT-IR, 1 H NMR, 13 C NMR, UV/vis and TGA. The H 0 (Hammett function) value of the IL was also determined. The IL as catalyst was applied to the catalytic synthesis of biodiesel from free fatty acids (FFAs). The influencing factors, such as the type and amount of catalyst, reaction time, molar ratio of fatty acid to methanol and reaction temperature, were investigated. The results indicated that the long-chain Brønsted acid IL showed high catalytic activity and fair reusability. Esterification was accomplished under the following optimized conditions: molar ratio of alcohols to FFA at 1.5 : 1, mole fraction of ionic liquid at 10%, 60 1C, and 3 h. The products could be separated from the catalyst system by liquid-liquid biphase separation at room temperature with good yields of 92.5% to 96.5%. The catalyst could be reused nine times after the removal of water and alcohol. Therefore, the long-chain Brønsted acid IL has good potential for the synthesis of biodiesel from low-cost feedstocks such as waste oil and woody plant oils.

Life Cycle Cost and Sensitivity Analysis of Reutealis trisperma as Non-Edible Feedstock for Future Biodiesel Production

et al. 2017

Abstract:The use of non-edible, second-generation feedstocks for the production of biodiesel has been an active area of research, due to its potential in replacing fossil diesel as well as its environmentally friendly qualities. Despite this, more needs to be done to remove the technical barriers associated with biodiesel production and usage, to increase its quality as well as to widen the choice of available feedstocks; so as to avoid over-dependence on limited sources. This paper assesses the feasibility of using a local plant, Reutealis trisperma, whose seeds contain a high percentage of oil of up to 51%, as one of the possible feedstocks. The techno-economic and sensitivity analysis of biodiesel production from Reutealis trisperma oil as well as implementation aspects and environmental effects of the biodiesel plant are discussed. Analysis indicates that the 50 kt Reutealis trisperma biodiesel production plant has a life cycle cost of approximately $710 million, yielding a payback period of 4.34 years. The unit cost of the biodiesel is calculated to be $0.69/L with the feedstock cost accounting for the bulk of the cost. The most important finding from this study is that the biodiesel from Reutealis trisperma oil can compete with fossil diesel, provided that appropriate policies of tax exemptions and subsidies can be put in place. To conclude, further studies on biodiesel production and its limitations are necessary before the use of biodiesel from Reutealis trisperma oil may be used as a fuel source to replace fossil diesel.

“…Because of environmental concerns and the ongoing depletion of fossil fuels, biodiesel has attracted considerable attention during the past decade as an alternative, green and renewable fuel [1]. Biodiesel is generally produced from vegetable oils or animal fats by transesterification of triglycerides [2][3][4] or by esterification of free fatty acids (FFAs) with short-chain aliphatic alcohols [5][6][7][8][9]. However, the mineral acids that are employed for this purpose in industrial processes cannot be recycled and have other disadvantages [10].…”
