PEMBUATAN BIODIESEL BERBAHAN BAKU MINYAK DARI AIR LIMBAH COOLING POND DENGAN KATALIS ESTERIFIKASI KARBON SULFONAT SERTA KATALIS TRANSESTERIFIKASI K2CO3 DAN Na2CO3
While high production of palm oil improves the community’s economy, it has the potential to damage the environment because it produces wastewater containing quite a lot of residual oil. The wastewater caused by this production process flows into the cooling pond before it is further processed in aerobic and anaerobic ponds. The residual oil contained in the cooling pond can be collected and used, such as raw material for biodiesel production. This study aimed to produce oil-based biodiesel in a cooling pond through the esterification method with a sulfonated carbon catalyst and a transesterification method with K2CO3 and Na2CO3 catalysts. The catalyst ratio was varied, i.e. 8-16% for esterification and 1-3% transesterification. The reuse performance of sulfonated carbon catalysts was varied three times. Based on the research results, sulfonated carbon catalysts were proven to be effective as heterogeneous catalysts in the esterification process because they can reduce acid levels to below 5 mgKOH/gOil. A sulfonated carbon catalyst ratio of 12% is the optimum ratio to reduce the acid level to 4.62 mgKOH/gOil. Reused sulfonated carbon reduces the acid level to 6.9 mgKOH/gOil at the first reuse. In the transesterification process, the K2CO3 catalyst has a better performance than Na2CO3 because it meets the characteristics of SNI for Biodiesel. The optimum ratio of the K2CO3 catalyst is 1.5%. The biodiesel produced has met the characteristics of SNI for Biodiesel of 7182:2015 with the acid number (0.412 mgKOH/gOil), saponification number (196.609 mgKOH/gOil), free glycerol (0.008%), ester content (96.99%), viscosity kinematics (4.044 cSt), density (865 kg/m3), and oxidation stability (10.46 hours).
