“…Hsieh et al [24] achieved 95% yield of FAME over Ca(C3H7O3)2/CaCO3 catalyst with the reaction temperature of 60 o C using conventional reactor. On transesterification of soybean oil over fixed bed reactor found by Ren et al [26], the conversion of biodiesel achieved 95.2 % within a residence time of 56 min at temperature reaction of 50 o C and feed flow rate of 1.2 mL/min. Shibasaki-Kitakawa et al [33] investigated a continuous transesterification of crude triolein with ethanol in fixed bed reactor with conversion achieved 80 % at residence time of 60 min.…”

“…For the case of continuous reactor system, a fixed bed tubular continuous reactor to produce biodiesel has been developed by Hsieh et al [24]. Other researchers, Feng et al [25] and Ren et al [26], proposed continuous reactor using fixed bed reactor for biodiesel synthesis which focused on continuous esterification and continuous transesterification, respectively. However, the continuous fixed bed catalytic reactor systems have some weaknesses, such as: water content in oil hindered the ester formation with the esterification, deactivating catalyst active sites, and hydrolyzing FAME.…”

Biodiesel synthesis through transesterification of soybean oil with methanol on hybrid catalytic-plasma reactor over sulphated zinc oxide (SO4 2-/ZnO) active acid catalyst was investigated. This research was aimed to study effects of Weight Hourly Space Velocity (WHSV) and the catalyst diameter on performance of the hybrid catalytic-plasma reactor for biodiesel synthesis. The amount (20.2 g) of active sulphated zinc oxide solid acid catalysts was loaded into discharge zone of the reactor. The WHSV and the catalyst diameter were varied between 1.55 to 1.546 min -1 and 3, 5, and 7 mm, respectively. The molar ratio of methanol to oil as reactants of 15:1 is fed to the reactor, while operating condition of the reactor was kept at reaction temperature of 65 o C and ambient pressure. The fatty acid methyl ester (FAME) component in biodiesel product was identified by Gas Chromatography -Mass Spectrometry (GC-MS). The results showed that the FAME yield decreases with increasing WHSV. It was found that the optimum FAME yield was achieved of 56.91 % at WHSV of 0.895 min -1 and catalyst diameter of 5 mm and reaction time of 1.25 min. It can be concluded that the biodiesel synthesis using the hybrid catalytic-plasma reactor system exhibited promising the FAME yield.

“…Environmental concerns have led to the search for solid catalysts which are eco-friendly and effective [18]. The chemical process used to obtain biodiesel is based on the solid in the system catalyzing the reaction to reduce the time and the cost of the process through the reuse of the catalyst, decreasing the level of impurities in the reaction products and carrying out the operation in a continuous fixed bed [19][20][21][22].…”

With the aim of developing a process of biodiesel production that is environmentally benign much interest has been focused on the use of solid base catalysts, such as calcium oxide, for the transesterification of vegetable oils with methanol. In the study reported herein a recycling reactor was used in bench scale, with the capacity to produce 3 L of biodiesel. The reactor was designed especially for this research study. A full 2 3 factorial plan was used to evaluate the process parameters related to this study, in particular, the catalyst concentration, the alcohol to oil molar ratio and the reaction time. Using this equipment for the transesterification reaction resulted in the recovery of the excess alcohol. The reaction products were characterized using gas chromatography and liquid analysis to determine the ester and calcium concentrations, respectively. The main conclusions drawn were that the best conversion percentage (100% of biodiesel) was reached when the methanol:oil molar ratio was 6:1, the reaction time was 75 min and the catalyst mass was 3% in relation to the oil mass used in this process. The CaO concentration determined exceeded the limit of concentration defined by legislation and thus a secondary operation was carried out to purify the reaction products obtained. The results of this study showed a high performance, and the proposed experiment could be used as a new and innovative way to produce biodiesel in the future.

Preliminary testing of hybrid catalytic-plasma reactor for biodiesel production through transesterification of soybean oil with methanol over modified-carbon catalyst was investigated. This research focused on synergetic roles of non-thermal plasma and catalysis in the transesterification process. The amount of modified-carbon catalyst with grain size of 1.75 mm was placed into fixed tubular reactor within discharge zone. The discharge zone of the hybrid catalytic-plasma reactor was defined in the volume area between high voltage and ground electrodes. Weight Hourly Space Velocity (WHSV) of 1.85 h -1 of reactant feed was studied at reaction temperature of 65 o C and at ambient pressure. The modified-carbon catalyst was prepared by impregnation of active carbon within H2SO4 solution followed by drying at 100 o C for overnight and calcining at 300 o C for 3 h. It was found that biodiesel yield obtained using the hybrid catalytic-plasma reactor was 92.39% and 73.91% when using active carbon and modified-carbon catalysts, respectively better than without plasma. Therefore, there were synergetic effects of non-thermal plasma and catalysis roles for driving the transesterification process. Copyright
