Hence alternative sources of energy for running our generators, automobiles etc. The use of biodiesel and the requirement of improving its production in a more efficient and sustainable way are becoming more and more important. The experimental design was used in the optimization process because this methodology permitted a . These and other reasons have led to medium- and large-scale biodiesel production trials in several countries, using non-edible oils such as castor oil, tung, cotton, jojoba and jatropha. are being considered worldwide. The results obtained show a 95.20% yield under optimal conditions (1:8 oil:methanol, 11% of catalyst, 60 min, PDF Optimization of Castor Oil Transesterification using ... (PDF) Biodiesel Production from Castor Oil by Using ... for the production of biodiesel that can effectively be utilized in diesel engines. The studied variables were reaction temperature, catalyst concentration, and ethanol:castor oil molar ratio. Biodiesel production through chemical technology, that is, transesterification, has been developed and widely used. Mexico's production of biodiesel from castor oil is expected to exceed nine million liters by 2030. Both the edible and non-edible vegetable oils can be used as the raw materials for the biodiesel. Ricinoleic Biodiesel Production From Castor Oil Under Subcritical In fact, castor oil has one of the highest cetane numbers amongst vegetable oils, and all the other biodiesel contenders have cetane numbers slightly lower than that for castor oil (The cetane number of petro diesel is about 45, while for most biodiesel, the cetane number falls in the range 45-65) (See Biodiesels from Vegetable Oils - PDF) Biodiesel Manufacturing Plant | Biodiesel Plant Suppliers biodiesel production lies in the fact that no foodstuffs are spent to produce fuel [4]. Castor oil is an excellent raw material in terms of price and quality, but especially this non-edible vegetable oil does not have any issues or compromise food security. A factorial design was cases make castor oil and ricinoleic acid becoming one of valuable chemical feedstocks (Chakrabarti and Ahmad, 2008). Animal fats are • India supplies over 70% of the total production of castor oil in the world. Biodiesel can be synthesized by transesterification process using acid or base catalyst. In this work, biodiesel production from castor oil has been synthesized by homogenous alkaline transesterification. This paper presents the result of investigations carried out in studying the emission and performance of diesel engine using the castor biodiesel and its blend with diesel from 0% to 40% by volume. diesel production as it is time saving, and we can opti-mize biodiesel production on the pilot scale with the experimental data optimized by using ANN. Biodiesel is considered an alternative replacement for petroleum diesel, and enzymatic reaction is one method for biodiesel production. The methyl ester content under these optimum conditions was 94.5% w/w of oil, and all of the measured properties Castor was seeded, plants grew and seeds were manually harvested after 2 years. In this work, biodiesel production from castor oil has been synthesized by homogenous alkaline transesterification. Although palm oil seems to be a promising source of biodiesel in Colombia because of the productive capacity already in place, it was decided to explore the production of the biofuel from castor oil. Since the source plant is commonly found in a wild state in many parts of the Download Free PDF. In this research work, castor oil was demonstrated to be an alternative feedstock for obtaining biodiesel. The CO. 2. released during combustion of biodiesel can be re-cycled through next crop production, therefore, no addi-tional burden on environment [7]. cases make castor oil and ricinoleic acid becoming one of valuable chemical feedstocks (Chakrabarti and Ahmad, 2008). Besides that, biodiesel produced from castor oil is low cost compared to production of biodiesel from other oils regarding to its solvability in alcohol transesterification could occur without usage of many excess heating equipment They determined the optimum process parameters as the reaction time of 40 min, reaction temperature of 35.5 °C, oil:methanol molar ratio of 1:8.24, and catalyst concentration of 1.45% KOH. Energy Fuels 2009, 23, 5636-5642 : DOI:10.1021/ef900403j Published on Web 11/02/2009 Biodiesel Production from Castor Oil: Optimization of Alkaline Ethanolysis Nı´ vea de Lima da Silva,* C esar Benedito Batistella, Rubens Maciel Filho, and Maria Regina Wolf Maciel School of Chemical Engineering, State University of Campinas P.O. synthesis processes, biodiesel productionand many referencescan be found in the background literature [33, 47-49]. The flash point values of castor methyl esters are lower than that of castor oil. 3.1. transesterification for biodiesel production. With increase in the demand of petroleum products the prices of petrol & diesel are increasing worldwide. • Since the freezing point of castor oil biodiesel is high, it The acid-based catalyzed transesterification system was used to produce castor biodiesel and the highest yield of 82.5% was obtained under the optimized condition. Chapter 2 Introduction to Biodiesel Production biodiesel production lies in the fact that no foodstuffs are spent to produce fuel [4]. Applied Biochemistry and Biotechnology, 2009. The reported study discusses biodiesel production from castor oil using methanol. • The Indian variety of castor has 48% oil content of which 42% can be extracted, while the cake retains the rest. Figure 7 Yield. Recently, the use of castor oil has attracted attention for producing and optimizing biodiesel production, due to high content of ricinoleic fatty acid and the possibility to esterify with only methanol, which assures low production costs. Pages 3 This preview shows page 1 - 2 . Hence alternative sources of energy for running our generators, automobiles etc. This work presents the biodiesel production from castor oil with bioethanol from sugar cane (also called here ethanol) in presence of sodium ethoxide and sodium hydroxide as catalysts. Waste MFL seed shells, carbonized and steam activated for surface modification to enhance adsorptive properties were then doped with H 2 SO 4 to develop a heterogeneous catalyst capable of facilitating esterification of the oil to form an ester rich product. bran oil, mahua oil, and castor oil (ricinus communis) might be studied and explored as a feedstock for biodiesel production [8-10]. The pretreated castor oil was ready to be used for biodiesel production. he experimental results were illustrated in Figure 5 shows the biodiesel yield from transesteriication of castor indicating that the molar ratio of methanol to oil has a oil at diferent reaction temperature from 50∘ C to 70∘ C. signiicant impact on the biodiesel yield. This work presents the biodiesel production from castor oil with bioethanol from sugar cane (also called here ethanol) in presence of sodium ethoxide and sodium hydroxide as catalysts. Download Free PDF. Introduction fluctuations have generated the desirability to develop 1.1 Background renewable fuels to 92.0% biodiesel yield was obtained by using the . Castor was seeded, plants grew and seeds were manually harvested after 2 years. As the free fatty acid content in castor oil is more than 1%, an acid catalyst namely, H 2 SO 4 has been used for esterification. Additionally, biodiesel from castor oil has different advantages over conventional diesel. The castor oil was then pretreated with acid esterification to reduce the free fatty acid contents of the oil to less than 0.5% .
