Optimization of Biodiesel (Rubber Seed Oil) Process Parameters using Taguchi Method Based on Experimental Procedure in A Batch Stirred Tank Reactor

Due to the increase in the demand for an alternate fuel the research studies towards searching for a low cost source and optimum conditions with new reactors were gaining momentum. Hence the present investigation is focused on the design of a batch stirred tank reactor with two different impellers to produce biodiesel with the use of rubber seed oil. Further an experiment was conducted in optimizing the process parameters using Taguchi methodology. The Taguchi methodology is mainly focused on the enhancement of the product produced and this is the most precise method used. The best combinations were obtained through the L9 orthogonal array. The reactor specifications were fixed to be 7.5cm. height, 7.5cm diameter, 2.5 cm agitator diameter, 0.625cm baffle thickness with 2.5cm as distance between bottom of the tank and impeller. Two impellers with 0.5cm. Width, 0.625cm length and others with 1.1cm length were used to test the individual performance towards yield. The optimum conditions obtained were found to be Impeller typeStraight blade impeller, Temperature- 65ºC, Time - 45min, Reactant ratio - 1:6, Catalyst amount- 22.46% (mol% of Oil), and Impeller Speed- 500rpm with the yield of 88 % . Hence BSTR reactors could be scaled up for translational research studies too.

The molar ratio of methanol to rubber seed oil (RSO), catalyst loading, and the reaction time of RSO biodiesel production were optimized in this work. The response surface methodology, using the Box–Behnken design, was analyzed to determine the optimum fatty acid methyl ester (FAME) yield. The performance of various nanomagnetic CaO-based catalysts—KF/CaO-Fe3O4, KF/CaO-Fe3O4-Li (Li additives), and KF/CaO-Fe3O4-Al (Al additives)—were compared. Rubber seed biodiesel was produced via the transesterification process under subcritical methanol conditions with nanomagnetic catalysts. The experimental results indicated that the KF/CaO-Fe3O4-Al nanomagnetic catalyst produced the highest FAME yield of 86.79%. The optimum conditions were a 28:1 molar ratio of methanol to RSO, 1.5 wt % catalyst, and 49 min reaction time. Al additives of KF/CaO-Fe3O4 nanomagnetic catalyst enhanced FAME yield without Al up to 18.17% and shortened the reaction time by up to 11 min.

Biodiesel can help to reduce the world‘s dependence on fossil fuels and which also has significant environmental benefits. Biodiesel is a mixture of fatty acid methyl esters (FAME) obtained via transesterification of vegetable oils or animal fats with an alcohol. The rubber seed oil (RSO) is chosen as a potential non-edible vegetable oil for the production of biodiesel. The oil was extracted from the seed by using pressurized liquid extraction (ASE). The percentage rubber seed oil extracted from 2.6 kilograms rubber seed was obtained 35%. The acid value of RSO has reduced from 52.3 mg KOH/g to 0.8 mg KOH/g while FFA% value has reduced from 35% to 1.18% after acid esterification was applied to RSO. The oil was proceed with base transesterification where the triglycerides from the oil were converted into FAME. The optimization of transesterification process was performed in order to determine the optimum conditions that give the highest FAME yield. Result shows that optimum conditions of the transesterification of rubber seed oil were 1:6 of oil to methanol mass ratio ,30 wt% KOH catalyst, 60 oC reaction temperature and 60 minutes reaction time, that offering the highest biodiesel yield of 96%.
