“…, the optimum condition was achieved after 300 min at a reaction temperature of 90°C. High reaction temperature increases the reaction rate because of the reduction in viscosity of the oil , and then the reaction needs shorter reaction time. High reaction temperature also minimizes the initial mass transfer limitation in the reaction system.…”

The production of biodiesel from yellow grease containing a low level of free fatty acids was investigated in this study. The kinetic transesterification of a molar ratio of (1:5) yellow grease to dimethyl carbonate was investigated. The experiments were conducted under various kinetic parameters, such as the use of a CH4O3S catalyst, and the effect of the reaction temperature (70°C), time (45 min) and stirring rate (125 rpm) were studied to determine the best possible kinetic conditions. A maximum yellow grease biodiesel yield of 94% was obtained. The properties of the biodiesel, such as the kinematic viscosity at 40°C, specific gravity at 25°C, flash point, pour point, cloud point, and copper strip corrosion level, were tested and found to conform to the biodiesel quality standards ASTM D6751 – 02. This research will provide a highly efficient, cost‐effective, eco‐friendly, and simplified process for one‐step biodiesel production from yellow grease. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 802–807, 2017

“…The fuel consumption was slightly enhanced for the engine supplied with Biodiesel and its blends compared to the supply with Eurodiesel fuel. Syamsuddin and Hameed [90] conducted synthesis of glycerol free-methyl esters (FAME) for the transesterification of Jatropha oil utilizing dimethyl carbonate (DMC) as methylating agent over heterogeneous Ca-La mixed-oxide catalyst. The optimal reaction conditions occurred at a 4:1 molar ratio of DMC to oil, 150 °C reaction temperature, 120 min reaction time, and 3 wt.% of catalyst loading allowing obtaining conversion and yield of 99.84%.…”

This papers presents the results of analysis done on a compression-ignition engine supplied with methyl ester of rapeseed oil (Yellow Grease), methyl ester of goose fat (Brown Grease) and pure diesel. The analysis included the engine characteristics, emissions and fuel consumption. Results also include chromatographic analysis for all of the three fuels. Additional evaluation was done on a vehicle idling and under load.

“…Katalis heterogen dapat digunakan kembali dalam reaksi setelah dipisahkan dari produk. Hal ini dikarenakan katalis heterogen tidak menyatu dengan biodiesel maupun gliserol yang dihasilkan, sehingga proses pemisahan katalis dapat dilakukan dengan mudah [16]. Reaksi dilakukan pada kondisi terbaik yaitu rasio minyak : metanol sebesar 1:12, waktu reaksi 180 menit, dan jumlah katalis 6% dari berat minyak dengan menggunakan katalis abu kulit alpukat yang dikalsinasi pada suhu 650 o C. Hasil yang diperoleh diperlihatkan pada Tabel 6.…”

Biodiesel is synthesized through a transesterification reaction with the help of a catalyst and generally uses a homogeneous catalyst. Heterogeneous catalysts can be synthesized from waste biomass such as avocado peel through a calcination. The purpose of this study was to examine the effect of variations in calcination temperature (550, 650, and 750oC) on the performance of the catalyst for biodiesel production and to analyze the effect of differences in the amount of catalyst (4, 6, 8, and 10% by weight of oil) used in the transesterification process on biodiesel yield. The catalysts were characterized by XRD, SEM-EDX, and FTIR. The results of the characterization of the catalyst showed that the dominant active phase of the catalyst was potassium (K). The highest biodiesel yield was obtained when using avocado peel ash as a catalyst which was calcined at a temperature of 650oC and using 6% catalyst by weight of oil. In the transesterification reaction the composition of the biodiesel product was analyzed using GC-MS and resulted that the palmitic acid was the most abundant composition in biodiesel. The biodiesel products produced were characterized for its density, viscosity, and acid number and have met the standard of SNI 7182:2015.
