Publisher : Universitas Gadjah Mada

This research was aimed to study the effect of glycerol separation on palm oil transesterification. Objectives of this study were to suppress the use of excess methanol and shorten the processing time. This research consisted of: design-build reactor, the effect of the glycerol separation on the transesterification reaction, characterization of biodiesel, and mass balance analysis. The reactor was designed by integrating circulate stirrer pump, static mixer, and sprayer that will bring out the intense reaction in the outer tank reactor. The experiment in this research was the treatment of decreasing the quantity of methanol to 5:1 molar ratio and reducing of processing time to 20 min, which was arranged in a completely randomized factorial design. The result showed that, (i) the stirring system was effectively worked outside the reactor tank, and in its reactor tank occurred glycerol separation during the process; (ii) the rate of glycerol during the process followed the inverse regression equation of Ŷ = 66.44-351.17 X-1; (iii) the decrease in the level of methanol to 5:1 molar ratio and the reduction of processing time to 20 min in this engineering did not influence the biodiesel yield and quality that met the SNI 04-7182-2006 standard.

AbstractOil Palm Empty Fruit Bunch (OPEFB) is a type of solid waste from the palm oil processing industry. The components of OPEFB include cellulose, hemicellulose, and lignin. OPEFB has a large cellulose content, so it possesses the potential to be used as a bioplastic material. The purpose of this research was to examine the stages of the bioplastics' production process and its characterization. The cellulose content of OPEFB as raw material and during the isolation process which includes hydrolysis, delignification, pulping, and bleaching are 39.59%, 56.00%, 59.85%, 61.48%, and 68.20%, respectively. Cellulose isolation produces α-cellulose content of 97.87%. The resulting cellulose acetate has an acetyl content of 25.93%. The bioplastics were then characterized to determine the effect of cellulose acetate, starch, chitosan, and glycerol on the physical and mechanical properties of the plastics. The results of the physical properties characterization include biodegradability, water absorption, and density with values of 78.73%, 38.26%, and 1.2% respectively. The results of the mechanical properties characterization include tensile strength, elongation, and modulus of elasticity with values of 0.729 MPa, 4.13%, and 17.5 MPa, respectively. The functional groups in the bioplastics, which are O-H, C-H, C-O, C=O, and N-H, are produced from the mixing process between cellulose acetate, starch, chitosan, and glycerol.

The study consisted of reactor design used for transesterification process, effect of glycerol separation on transesterification reaction, determination of biodiesel quality, and mass balance analysis. The reactor was designed by integrating circulated pump/stirrer, static mixer, and sprayer that intensify the reaction in the outer tank reactor. The objective was to reduce the use of methanol in excess and to shorten the processing time. The results showed that the reactor that applied the glycerol separation was able to compensate for the decreased use of the reactant methanol from 6:1 to 5:1 molar ratio, and changed the mass balance in the product, including: (i) the increase of biodiesel production from 42.37% to 49.34%, and (ii) the reduction of methanol in excess from 42.37% to 32.89%. The results suggested that the efficiency of biodiesel production could be increased with the glycerol separation engineering.
