Abstract

The increase in fuel use along with the decline in production of petroleum exploration activities encourages efforts to find alternative fuels, one of which is biodiesel from PFAD (Palm Fatty Acid Distillate) with production reaching 6,000,000 tons while its utilization is still low. Biodiesel production from PFAD using Fly ash (FA)-SO3H catalyst which is a heterogeneous catalyst through esterification method. FA used in this study was wet impregnated using 6M sulfuric acid (H2SO4) for 24 hours, so that the highest acid concentration was obtained at a calcination temperature of 500 ⁰C of 1.1654 mmol/gram. The research was conducted with Response Surface Method (RSM) with Box Behnken Design model in Design Expert 13 software and 13 runs were obtained. The resulting model from RSM was obtained as optimum conditions at catalyst loading (%-w) 5-10, methanol:PFAD molar ratio (n/n) 10:1-30:1, reaction time 3-5 hours and temperature 60 ⁰C. Based on the experimental results and ANOVA, the high conversion is influenced by the high catalyst loading and methanol:PFAD ratio (n/n), with the conversion obtained of 72.89% at catalyst loading of 10%-w, methanol:PFAD molar ratio of 20 (n/n) and time for 5 hours.

Abstract

Rice husk contains a lot of silica, so it is widely used as research material. One example is as a raw material for the synthesis of silica sulfate. Silica sulfate was synthesized using the sol-gel method with an impregnation time of 6 hours and 2 hours of calcination with variations in calcination temperature of 400-800oC. The analysis carried out on the silica sulfate catalyst is the analysis of acid concentration and FTIR. The best acid concentration results were 0.86 mmol/gram at 400oC. Characterization with FTIR showed similar peaks between silica and silica sulfate. The -OH and Si-O groups appeared at the peak of the analysis results, indicating that the synthesis of silica from rice husk had been carried out successfully. Modifying silica with sulfuric acid is not obvious through FTIR because the S-OH groups of sulfate ions overlap with the silica atoms in siloxane. The resulting silica sulfate is used as a catalyst in the esterification reaction of oleic acid with methanol. The esterification process was carried out at 60oC and varied with independent variables, namely catalyst loading (5-10%-b), time (2-4 hours), and molar ratio (1:6-1:12). The experimental design was determined using the Response Surface Method (RSM) using Design Expert. From the study results, the best variation obtained was a conversion of 87.03% with a variation of catalyst loading of 7.5%-b, a time of 4 hours, and a molar ratio of 1:12.

Abstract

The high consumption of cooking oil in Indonesia is directly proportional to the production of used cooking oil waste that can pollute the environment. To overcome this problem, used cooking oil is used as a biodiesel feedstock using the plasma electrolysis method. Plasma electrolysis is a synthesis process by applying a high voltage to the process. This study aims to determine the effect of the plasma electrolysis method with variations in voltage (400 - 500 volts) and the type of reagent (methanol and ethanol) on % yield and characteristics of biodiesel. The process is carried out by reacting used cooking oil with a reagent that is given a voltage until an electric discharge occurs and two layers are formed and the calculation of the specific energy requirements for the synthesis process is carried out. The results show that at a voltage of 500 volts with methanol reagent produces a yield of 85.73% with characteristics according to the SNI 7128:2015 standard such as density 888.36 Kg/m3, viscosity 5.79 Cst, acid number 0.39 mg - KOH/g, content ester 97.56% and flash point 117oC with the exception of water content 0.373%, with a specific energy requirement of 1758,031 J/mL.
