| description | Biodiesel production in Indonesia is obtained through the transesterification process of Crude Palm Oil with a byproduct, namely glycerol with a ratio of 1 m3 of biodiesel to produce 0,1 m3 of glycerol. Therefore, glycerol waste needs to be processed properly so that it can reduce waste and can provide added value to the biodiesel industry. One of the uses of glycerol in the industrial sector is as a bioaditive. This research was conducted to determine the optimum operating conditions to obtain solketal through a ketalization reaction between glycerol and acetone using Amberlite IR 120 Na catalyst.
The processing of glycerol and acetone into solketal products is carried out through a ketalization reaction using a 1: 3 mole ratio of reactants, 500 rpm stirring speed, 180 minutes reaction time by varying the temperature and the percent of catalyst mass. The temperature variations used are 40 oC, 45 oC, 50 oC, 55 oC and 60 oC and variations of the catalyst are 1%, 3%, 5% and 7%. The solketal results were analyzed by Gas Chromatography to prove the formation of solketa. Analysis of the physical properties of the synthesized solketal and performance tests on a diesel engine.
The optimum glycerol conversion was obtained at a temperature of 50 oC with a catalyst mass concentration of 5%, which is 75,04%. The test results of the physical properties of the pure solketal and the synthesized solketal are not too much different, the results of the synthetic solketal density are 1,202 g / mL while the pure solketal density is 1,063 g / mL with a flash point value that is quite high, namely 56,6 oC for the synthesized solketal results while the perfect solketal flash point is 90 oC. Solketal added to biodiesel as a bioaditive has been shown to improve the performance of diesel engines, this is evidenced by the increased value of power and decreased fuel consumption.
The optimum glycerol conversion was obtained at a temperature of 50 oC with a catalyst mass concentration of 5%, which is 75,04%. There are 2 mechanisms can be describe the ketalization reaction between glycerol and acetone into solketal, namely model 1, the pseudo homogeneous model and there is an intermediate product and model 2, the pseudo homogeneous model with reversible reactions with each Eapp value of 141,69 kJ / mol and 525678,34 kJ / mol. The test results of the physical properties of the pure solketal and the synthesized solketal are not too much different, the results of the synthetic solketal density are 1,202 gr / mL while the pure solketal density is 1,063 g / mL with a flash point value that is quite high, namely 56,6 oC for the solketal synthesis results, while the perfect solketal flash point is 90 oC.
