“…The temperature of the reactor has been maintained at a desired level by heater temperature. The more detail information of newly designed four orifice plates had been reported in previous paper (Chuah et al, 2015b). The diameter, hole number, total flow area and total perimeter values of the orifice plates are plate 1 -4.58 mm, 1, 16.5 mm 2 and 14.39 mm, plate 2 -1.00 mm, 21, 16.5 mm 2 and 65.98 mm, plate 3 -2.00 mm, 9, 28.3 mm 2 and 56.56 mm and plate 4-3.00 mm, 5, 35.3 mm 2 and 47.13 mm.…”

“…However, there is no detailed information in the literature regarding the hole spacing and distribution pattern of holes in the plates. So far it has not been many works published on the design of the plate geometry, which is a crucial factor for designing the large scale reactor and also enhance the performance of methyl ester conversion (Chuah et al, 2015b). This study exploits the results of the previous work (Chuah et al, 2015b), which investigated the transesterification reaction of waste cooking oil (2.04 mg KOH/g) in a pilot HC reactor.…”

The fossil fuels usage in the world has been increasing continuously due to the energy demand, which leads to a decline in fossil fuel reserve. The increase in the cost of fossil fuels and the environmental pollution lead a search for an alternative energy. The energy should be renewable, harmless and non-polluting. Used cooking oil methyl ester is derived through transesterification process by using Used Cooking Oil (UCO) and methanol in the presence of Potassium hydroxide (KOH) catalyst. Emission characteristics have been investigated the used cooking oil and their blends with diesel.B20K and B100K reduced the carbon monoxide (CO) by 4.5% and 32.27%, hydrocarbon (HC) emission by 28.26% and 45.65%, particulate matter by 3% and 19.13% and smoke emission by 7.25% and 28.27%, respectively compared to diesel at full load. On the other hand, B20K and B100K increased the NOx emission by 7.3% and 18%, respectively compared to diesel at the rated output. The emissions of carbon monoxide, hydrocarbon, smoke density and particulate matters were reduced and there was a slight increase in oxides of nitrogen with the used cooking oil methyl ester (UCOME), as a renewable harmless and non-polluting substitute for diesel engines.

“…Thus, they need to be converted into biodiesel via a number of processes such as transesterification (Sharma et al, 2008). In the transesterification reaction, triglycerides react with an alcohol (methanol or ethanol) in the presence of a catalyst (Chuah et al, 2015b). The catalyst could be either acidic or basic depending on the free fatty acid content of the oil feedstock (Georgogianni et al, 2009).…”

“…Various non-edible oils have been used for biodiesel production through transesterification of triglycerides by using different methods, such as mechanical stirring, supercritical procedure (Ong et al, 2013), ultrasonic techniques (Ji et al, 2006), hydrodynamic cavitation (Chuah et al, 2015b), and microwave (Lee et al, 2010). However, only a few studies have reported on biodiesel production from Kapok seed oil (KSO).…”

Please cite this article as: Bokhari A., Chuah L.F., Yusup S., Ahmad J., Shamsuddin M.R., Teng M.K. Microwave-assisted methyl esters synthesis of Kapok (Ceiba pentandra) seed oil: parametric and optimization study. The depleting fossil fuel reserves and increasing environmental concerns have continued to stimulate research into biodiesel as a green fuel alternative produced from renewable resources. In this study, Kapok (Ceiba pentandra) oil methyl ester was produced by using microwave-assisted technique. The optimum operating conditions for the microwave-assisted transesterification of Kapok seed oil including temperature, catalyst loading, methanol to oil molar ratio, and irradiation time were investigated by using Response Surface Methodology (RSM) based on Central Composite Design (CCD). A maximum conversion of 98.9 % was obtained under optimum conditions of 57.09 °C reaction temperature, 2.15 wt% catalyst (KOH) loading, oil to methanol molar ratio of 1:9.85, and reaction time of 3.29 min. Fourier Transform Infra-Red (FT-IR) spectroscopy was performed to verify the conversion of the fatty acid into methyl esters. The properties of Kapok oil methyl ester produced under the optimum conditions were characterized and found in agreement with the international ASTM D 6751 and EN 14214 standards.© 2015 BRTeam.
