The disadvantages of conventional biodiesel synthesis trigger the birth of new biodiesel synthesis methods using the DBD plasma reactor. The conventional methods with homogeneous and heterogeneous catalysts have significant constraints that the formation of glycerol compounds in large enough quantities that require considerable energy. The aim of present experiment is to design DBD non-thermal plasma reactor coaxial pipe type and to do its performance test in converting biodiesel The feed stock used are palm oil, ethanol, and argon gas as plasma carrier. Such a chemical reactor, this plasma reactor is also influenced by reaction kinetics and hydrodynamic factors. From this research, it can be seen that the optimum feed and gas flowrate being operated is 1.64 and 41.67 mL/s. The plasma reactor is used in the form of a quartz glass tube surrounded by a SS-314 spiral coil as an outer electrode. The applied operating conditions are 1 : 1 molar ratio of methanol/oil, ambient temperature of 28 - 30 °C, and pressure 1 bar. From this performance test, it is found that this plasma reactor can be used to synthesize biodiesel from palm oil and methanol without catalyst, no formation of soap, and minimal byproducts.

Biodiesel is one of renewable energy alternatives, as a substitution of diesel engine fuel or diesel oil. Indonesian palm oil contains the fatty acids needed for the synthesis of FAME (fatty acid methyl ester) as the basic ingredient of biodiesel. Conventional biodiesel synthesis methods, which generally use transesterification reactions with homogeneous and heterogeneous catalysts, have significant constraints due to the formation of relatively large quantities of glycerol compounds as well as requiring complex separation processes and considerable energy. The DBD (Dielectric Barrier Dicharge) plasma reactor can be a solution to overcome the above shortcomings. The purpose of this research is to perform performance test from design result of DBD plasma reactor especially biodiesel making process. The analytical methods for FAME products use GC-FAME and FTIR (Fourier Transform Infra Red) for chemical conversion related between triglyceride reactants and biodiesel products. The best operating conditions obtained from the hydrodynamic test showed a mixed flowrate of triglyceride/alcohol of 0.1318 L/min, gas flowrate (plasma carrier) of 2.5 L/min and a voltage of 220 Volts alternating current. Biodiesel is produced using palm oil and methanol as a liquid reactant and using argon as a plasma carrier gas in the reactor. Plasma is produced in DBD reactor using 1-phase PLN power, with a voltage of 220 VAC. The main advantage of the conversion process in this plasma reactor is the production of FAME without the formation of significant glycerin byproducts and the use of homogeneous or heterogeneous catalysts.

AbstractThis work investigates the effect of simultaneous ultrasound-microwave irradiation on palm oil transesterification and uncovers optimal operating conditions. Response surface methodology (RSM) has been used to analyze the influence of reaction conditions, including methanol/palm oil molar ratio, catalyst concentration, reaction temperature and irradiation time on biodiesel yield. RSM analyses indicate 136 s and 129 s as the optimal sonication and microwave irradiation times, respectively. Optimized parameters for full conversion (97.53%) are 1.09% catalyst concentration and a 7:3.1 methanol/oil molar ratio at 58.4°C. Simultaneous ultrasound-microwave irradiation dramatically accelerates the palm oil transesterification reaction. Pure biodiesel was obtained after only 2.2 min while the conventional method requires about 1 h.

Abstract Oxidative decomposition of chlorobenzene diluted in air was carried out in a dielectric barrier discharge reactor. In order to understand the role of the ground electrode, various reactor configurations were tested. Among silver paste, copper wire and aluminum foil tested as the outer electrodes, typical results indicated the best performance of silver paste, probably due to uniform distribution of microdischarges. Likewise, low flow rates gave better conversion and selectivity to gaseous products.
