Abstract

Palm oil is very potentially for turned in to biodiesel. In the process of making biodiesel with transesterification conventional required a long time because the reaction takes places in two phase. Adding the co-solvent can be a solution to makes the reaction time shorter. Methyl ester can be used as a co-solvent to makes the reaction in single phase between the oil and methanol so decrease the reaction time in biodiesel process. Methyl ester as a co-solvent is not need to separate after the last process because methyl ester is the main product of the reaction. The purpose of this research is to find out the effect of addition of co-solvent methyl ester and catalyst NaOH to produced the biodiesel from palm oil which has the good standard. According to the result was obtained that the best results of this process achieved at mass of co-solvent of 15% and reaction time of 20 minutes with mass of FAME 28.06 gr. Methyl ester density and acid value regards with SNI 04-7182-2006.

Abstract

Indonesia merupakan negara yang kaya akan sumber daya alam hayati sehingga dijuluki negara agraris namun sampai saat ini masih belum bisa memanfaatkan sumberdaya hayati secara optimal, salah satunya tanaman penghasil minyak atsiri. Indonesia menghasilkan 40–50 jenis tanaman penghasil minyak atsiri dari 80 jenis minyak atsiri yang diperdagangkan di dunia dan baru sebagian dari jenis minyak atsiri tersebut yang memasuki pasar dunia, diantaranya nilam, sereh wangi, gaharu, cengkeh, melati, kenanga, kayu putih, cendana, dan akar wangi. Melihat akan hal ini, potensi usaha melalui ekstrak minyak atsiri tanaman sangat terbuka lebar. Salah satu metode sederhana dan peluang usaha yang sangat bagus adalah mengekstrak minyak atsiri dari tanaman dan hasilnya dapat dimodifikasi menjadi aroma terapi. Untuk objek dasar dari terciptanya aroma terapi adalah lilin. Lilin adalah sumber penerangan yang terdiri dari sumbu yang diselimuti oleh bahan bakar padat,dimana lilin yang digunakan adalah juga merupakan bahan dari alam yaitu lilin lebah. Dengan demikian lilin aroma terapi yang dihasilkan pada penelitian ini adalah yang ramah lingkungan

Abstract

In the transesterification process, the problem is the low solubility of oil in methanol, so the reaction will run slowly. The solution to this problem is to add a co-solvent to increase the solubility so that a one-phase reaction will be formed. The co-solvent methyl ester is the right choice because it is a product of the reaction itself so that it does not require a separation process. The operating conditions of the study were mass of palm oil 250 g, mass of NaOH catalyst 0.8%wt, stirring speed 100 rpm, reaction temperature 60oC, the molar ratio of oil:methanol = 1:6, reaction time (5,10,15,20,25,30 minutes), and the mass of co-solvent (0,5,10,15%wt). The first stage of the research was to make co-solvent, then proceed with the transesterification reaction by adding  co-solvent which was carried out according to the research operating conditions. The optimum condition of the study was obtained at reaction time 30 minutes and the addition of co-solvent 5%, with yield 97.4171%. The density of FAME 0.88 g/mL and the concentration of FAME 99.963% which complied with SNI 7185-2015. The simulation results of ChemDraw for components of triglyceride+methanol+NaOH+co-solvent obtained kinetic energy 3479.0264 kJ/mol and dipole moment 43279.8007 debyes.

Abstract

In the process of making biodiesel with a transesterification reaction, an effective, efficient and inexpensive raw material is palm oil because of its abundant availability. In the transesterification process, the addition of methanol is deliberately exaggerated so that the reaction shifts towards the product and the reaction is more perfect and the excess methanol reagents in the process can be reused as reactants. This research was conducted to obtain optimal levels and yield of methyl esters by utilizing the residual methanol reaction. The transesterification process is carried out at 65°C, the molar ratio of palm oil: methanol is 1: 6, the mass of NaOH catalyst is 1% oil mass and the stirring speed is 150 rpm. The residual methanol from the transesterification reaction is used as a reactant in the subsequent transesterification reaction by varying the mass of the remaining methanol addition of the reaction which is 5%, 10% and 15% of the mass of the initial methanol and also varying the reaction time of 15, 30, 45, 60 and 75 minutes. From the results of the research, it was obtained the optimum conditions for the addition of 5% residual reaction methanol and 60 minutes reaction time, get a yield of 90.60% and a concentration of methyl ester 97.69% (meet SNI 7182: 2015). Methyl ester products at the optimum process conditions also meet SNI 7182: 2015 for densities of 0.85 gr / ml and acid valuesof0.42mg-KOH/gr.

Abstract

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.
