Biodiesel Synthesis

This paper reports the production of fatty acid methyl esters (FAMEs) and fatty acid ethyl esters (FAEEs) by the transesterification reaction of rubber seed oil (RSO) in supercritical methanol and ethanol without using any catalyst. Experiment were carried out in a batch reactor, and reactions were studied at 260, 280, 300 and 320 oC at a pressure of 8.1-19 MPa with various mole ratios of ethanol – to - methanol from 0 to 100%. The extent of the reaction was explored using a convertibility parameter, which corresponds to the maximum ester content attainable from the feedstock. The highest FAME and FAEE contents achieved were 91.8 % and 86.4%, respectively. Results show that transesterification of RSO in methanol was more efficient than that in ethanol; the temperature had the strongest influence.

Khaya Senegalensis

Biodiesel was produced by transesterifying Khaya senegalensis oil with methanol in the presence of Al2O3 as catalyst. Molar ratio of 15:1 (methanol to oil) was followed to shift the reaction to product side for more yield of fatty acid methyl esters (FAME) and the use of a heterogeneous catalyst enabled the reaction to proceed faster. The oil and biodiesel were characterized following ASTM standards. The free fatty acid, acid value, viscosity, specific gravity, moisture content, saponification value, pour point, cloud point were examined in this research and the result obtained show that Khaya senegalensis Seed Oil is a good for biodiesel production. The biodiesel obtained was separated from glycerol, washed with distilled water and dried. Samples of oil and biodiesel were scan within mid-infrared region of 4000 cm-1 – 400 cm-1 with fourier transform infrared spectrometer by agilent technologies. The spectra obtained were interpreted and analyzed with the aid of structure correlation chart. The results revealed that the biodiesel contained fatty acid methyl esters (FAME). The FTIR spectrum for the biodiesel revealed the functional groups with characteristics bands, C=O, -(CH2)n-, C-O, C=C and C-H in the spectrum.

The effective transesterification process to produce fatty acid methyl esters (FAME) requires the use of low-cost, less corrosive, environmentally friendly and effective catalysts. Currently, worldwide biodiesel production revolves around the use of alkaline and acidic catalysts employed in heterogeneous and homogeneous phases. Homogeneous catalysts (soluble catalysts) for FAME production have been widespread for a while, but solid catalysts (heterogeneous catalysts) are a newer development for FAME production. The rate of reaction is much increased when homogeneous basic catalysts are used, but the main drawback is the cost of the process which arises due to the separation of catalysts from the reaction media after product formation. A promising field for catalytic biodiesel production is the use of heteropoly acids (HPAs) and polyoxometalate compounds. The flexibility of their structures and super acidic properties can be enhanced by incorporation of polyoxometalate anions into the complex proton acids. This pseudo liquid phase makes it possible for nearly all mobile protons to take part in the catalysis process. Carbonaceous materials which are obtained after sulfonation show promising catalytic activity towards the transesterification process. Another promising heterogeneous acid catalyst used for FAME production is vanadium phosphate. Furthermore, biocatalysts are receiving attention for large-scale FAME production in which lipase is the most common one used successfully This review critically describes the most important homogeneous and heterogeneous catalysts used in the current FAME production, with future directions for their use.

Energy crises, depletion of fossil fuel reservoirs, environmental pollution, global warming, green house effect and starvation are becoming very serious problems in the modern world. Biodiesel is a liquid fuel which can be the best alternative for the fossil fuels. In this study, non-edible rubber seed oil (RSO) with high free fatty acid (FFA) content (45%) was used for the production of biodiesel. The process comprises of two steps, in the first step acid esterification was used to reduce the FFA and in the second step base transesterification was employed to convert the treated oil into rubber seed oil methyl esters (RSOMEs). The conversion yield of biodiesel was analyzed using gas chromatography. The fuel properties were tested using the standard procedure of ASTM D6751 and EN14214. All the properties were within the ranges of the biodiesel standards. The result shows that rubber seed oil is a potential non-edible source for biodiesel production.
