“…Addition of more catalyst might increase viscosity of the mixture in the reactor, which will increase the energy needed to meet the requirement of efficient mixing, and so the reaction could not be conducted well. The same phenomena were also reported by some researchers [15,16]. Besides, too little catalyst might not catalyze the transesterification reaction [15,17].…”

“…The same phenomena were also reported by some researchers [15,16]. Besides, too little catalyst might not catalyze the transesterification reaction [15,17]. The best yield of 96.8% was occurred at catalyst load of 8%, transesterification temperature of 65°C, and MTMR of 12:1.…”

“…However, if the MTMR is too high, it could reduce the yield of biodiesel. This was due to the fact that excessive methanol would dissolve glycerol and this phenomenon would suppress the transesterification of oil to biodiesel [15]. But, if the temperature is more than the boiling point of the solvent, volatilization of solvent (methanol) will occur, which will increase the vapour phase and the formation of three phases which leads to reaction limitations and lowering the rate of reaction.…”

In the present work, an attempt had been made to utilize chicken eggshells ash and natural zeolite as a promising catalyst for biodiesel formation. Solid chicken eggshells ash (CEA) was produced through the calcination of chicken eggshells. The CEA was mixed with natural zeolite at a mass ratio of 1:3. This mixture was then used as catalyst in biodiesel formation. Biodiesel was sunthesized via the transesterification of treated waste cooking oil (TWCO) with methanol at temperature of 55-65 o C, methanol to TWCO molar ratio (MTMR) of 8:1-14:1, reaction time of 90-210 min, and catalyst load of 6-10%. The properties of biodiesel obtained were measured such as methyl ester content, flash point, density, viscosity, and compared to the European Standard (EU 14214). The highest yield of 96.8% was occurred at a MTMR of 12:1, 65°C, 180 minutes, and 8 wt% of catalyst load. The results of this study confirmed that natural zeolite addition could improve the catalytic activity of CEA. Therefore, the combination of CEA and natural zeolite may be used as a low-cost catalyst in biodiesel formation.

“…The band at 2368-2337 cm -1 comes from C≡C vibrations, forwhile the peak at 1633 cm -1 appears as a result of C=C vibrations [17] . Peaks showing the presence of K2CO3 minerals appear at 1404-1388 cm -1 , the peak appears at 1041-1018 cm -1 that comes from PO-Si bond vibration, while the peak at 887-771 cm -1 indicates the presence of Fe-O [18] . From Figure 6, it appears that the intensity of the K2CO3 in Catalyst-2 is greater compared to Catalyst-1, which might relate to the amount of KOH being impregnated onto the catalyst.…”

Recently, many researchers have explored the potential use of ash as a catalyst, due to the availability of various mineral elements in it. The ashes themselves can be obtained from various agricultural waste of biomass, including from the burning of woods. In this study, the ash that was used as a raw material for a heterogeneous catalyst was obtained from the burning of gelam wood (Melaleuca leucadendron). After the burning, the ash was sieved to have particles of homogenous size. The ash was then activated with a solution of 1 M H2SO4 and 0.1 M KOH, consecutively. Potassium was then impregnated onto the activated ash using 30% and 60% (w/w) KOH solution, followed by calcination at 800 °C for 3 hours. The impregnated catalysts were then characterized with FTIR, XRD, and SEM-EDX. The catalyst was tested for its ability in the transesterification reaction of palm oil by varying the methanol to oil mole ratio, the amount of catalyst used, and the reaction time. The optimal reaction conditions for biodiesel production using this catalyst include a 12:1 methanol to oil mole ratio, 10.0% weight ratio of the catalyst (catalyst weight to the oil volume), 6 hours of reaction time at 65 °C and stirring speed of 600 rpm. By using this catalyst, the biodiesel production reached up to 99.0% in conversion rate, with a product that satisfactorily meets the ASTM D6751 standards in terms of its density, kinematic viscosity, and acid number. Keywords Catalyst, gelam wood ash, palm oil, biodiesel.

Research to explore the potential of rubber seeds kernel as a carbon source for the preparation of heterogeneous catalysts has been carried out. This study aimed to characterize rubber seed kernel carbon, impregnate it with KOH, and apply it as a heterogeneous catalyst in biodiesel synthesis. In this research, rubber seed kernel was powdered then carbonized in a furnace for 4 h at 500°C, followed by activation with HCl for 1 h and dried. The resulting activated carbon was impregnated with KOH solution for 3 h at 80°C. After pre-drying, it was calcined at 500°C for 3 h. The rubber seed kernel powder, activated carbon, and KOH impregnated carbon were characterized using SEM-EDX and FTIR. KOH impregnated carbon was used as a heterogeneous catalyst in coconut oil transesterification for biodiesel synthesis. The parameters studied were catalyst load (2 - 4%) and reaction temperature (55 - 65°C). Molar ratio of oil to methanol and time were set at 1:9 and 2 h, respectively. The highest yield (96.43%) was obtained at 3% catalyst load and reaction temperature of 60°C.
