“…The transesterification reaction is an equilibrium reaction so that if equilibrium has been reached, the addition of moles of methanol and the reaction time does not affect the increase in yield of methyl ester. Excessive use of methanol will cause an increase in the formation of glycerol in proportion to the formation of methyl esters (biodiesel), but glycerol will dissolve in excess methanol, making it difficult to separate biodiesel and glycerol Zukhriyah et al (2022) Figure 3 shows the relationship of the effect of reaction time on product density. It can be explained that at the beginning of the treatment the density was still too high, similar to the density of the raw material, which was 0.92 gr/ml, but at reaction times of 7, 10, and 13 minutes the density was consistent at 0.88 gr/ml which complied with SNI 7182:2015 biodiesel.…”

Used cooking oil is a waste oil derived from cooking oil that has the potential to be produced into biodiesel because it contains fatty acids and triglycerides like other vegetable oils, however, its utilization is still low. This study aimed to analyze the effect of co-solvent THF based on reaction time and oil: methanol molar ratio in the manufacture of biodiesel using used cooking oil as raw material. Transesterification is a method used in biodiesel production by reacting raw materials with alcohol. KOH1% is used as a catalyst in the process of converting used cooking oil into biodiesel. In its operation, reaction time variations of 5, 7, 10, 13, and 15 minutes and molar ratios of 1:3, 1:6, 1:9, 1:12, and 1:15 were used at a temperature of 65oC. The results showed that when entering the reaction time of 10 minutes the density and viscosity tend to be stable and meet the standards of SNI 7182:2015, namely the density is stable at 0.88 gr/ml and the viscosity is in the range of 4.6238 cSt-5.7336 cSt. Meanwhile, based on the molar ratio, it was obtained only at a molar ratio of 1:6 which is in accordance with the characteristics of biodiesel based on SNI 7182:2015 which has a density of 0.88 gr/ml and a viscosity of 4.6238 cSt. The best % yield was at a 1:6 molar ratio with a reaction time of 13 minutes, that is 88.8199% with a heating value of 33.0398 MJ/kg and a cetane number of 66.9. Based on the methyl ester test with GC-MS, the methyl ester (biodiesel) content in the product was 87.24%, dominated by Oleaic (9(Z)-Octadecenoic) acid or 49.33% oleic acid and Palmitic (Hexadecanoic) acid. or palmitic acid by 34.08%.

“…Proses transesterifikasi dengan katalis NaOH dan co-solvent metil ester yang telah dilakukan belum mendapatkan yield yang memuaskan ditinjau dari massa katalis, waktu reaksi dan massa penambahan cosolvent FAME. Pada transesterifikasi minyak kelapa sawit dengan co-solvent metil ester 15% dan katalis NaOH 1% wt., mendapatkan yield 57,33% pada waktu reaksi 15 menit dan suhu reaksi 70⁰ C [11]. Selain itu juga tidak dilakukan analisa total sifat fisik metil ester yang dihasilkan apakah sudah memenuhi standar biodiesel atau belum serta tidak dilakukan uji performance biodiesel yang dihasilkan pada motor bakar.…”

The process of transesterification is slow due to the low solubility of triglycerides in methanol. The limitation of mass transfer can be overcome by adding a co-solvent. Co-solvent FAME is the right choice because it is the product of the reaction itself so that it does not require a separation process. The purpose of this study was to examine the use of FAME as a co-solvent in the transesterification of palm oil and its application to the combustion engine. The operating conditions were palm oil mass of 250 gr, NaOH catalyst 1.2% wt, stirring speed 100 rpm, reaction temperature 70oC, ratio molar of oil:methanol =1:6, reaction time (5,10,15,20,25,30 minutes), and co-solvent (0,5,10,15% wt). After the optimum conditions are obtained, the next step is to make biodiesel on a semi pilot plant scale. Oil, methanol, NaOH and co-solvent were put into a stirred reactor and heated at a reaction temperature of 70⁰C. After the reaction is complete then it is flowed into the separator for separation by adding hot water to form 2 layers. The top layer is biodiesel which was analyzed and performance test on the combustion engine. The optimum condition of the process is a reaction time of 10 minutes and the addition of 10% co-solvent, with a yield of 76.7783%. The results of the analysis of SNI 7182:2012 states that biodiesel meets almost all requirements. From the biodiesel performance test on the combustion engine, B10 got quite satisfactory results for the torque and opacity test parameters.
