Impregnasi Naoh Pada Cao Dari Cangkang Kerang Darah (Anadara Granosa) Sebagai Katalis Untuk Produksi Biodiesel Dari Minyak Goreng Bekas

The development of heterogeneous base catalysts for biodiesel production by the transesterification reaction becomes favorite one because more environmentally friendly, more easily be separated from the rest of the processing biodiesel, and can be reused in order to reduce the cost of production biodiesel. Heterogeneous base catalyst often used to transesterification reaction is calcium oxide (CaO). In this research, CaO catalyst has been synthesized from blood cockle (Anadara granosa) shells calcined 900 oC for 10 hours. It impregnated by NaOH (1, 3, and 5%) with activated temperature 600 oC for 5 hours. 3% Na/CaO catalyst was the best catalyst for biodiesel production from waste cooking oils. XRD data showed the peaks of Calcite, Lime, and Portlandite. XRF analysis of catalyst containing ±97,315% CaO. Catalytic basicity of 2.04 mmol/g of benzoic acid with a surface area of 5.44 m2/g. Analysis of the morphology of the catalyst using SEM, 3% Na/CaO catalyst has a hexagonal shape and oval with a size of ̴5 µm.
The yield of biodiesel maximum was 86.05% with 60 oC of reaction temperature, 3.5 hours of reaction time, 350 rpm of stirring speed, 3 g weight of catalyst, and 1:6 mole ratio of oil:methanol. Biodisel obtained has a water content 0,019%, density 865 kg/m3, viscosity of 3,5 mm2/s, a flash point of 156 oc, 0,045% carbon residue, acid number 0,65 mg KOH/g, 212,57 mg saponification KOH/g, iodine number of 40,79 g-I2/100 g and 62,80 cetane number corresponding to the SNI for biodiesel (SNI 04-7182-2006). Methyl ester analysis of biodiesel production using GC-MS and dissolved metal content analysis using AAS showed that biodiesel contains 100% methyl ester and dissolved metals 4800 µg/kg.
