Leather Industry Waste (Demineralization): A Promising Substrate biodiesel production

Abstract

Developing fats and proteins to facilitate waste management and ways to generate electricity of renewable energy. Oil is extracted from this waste using a solvent extraction process. mountain This biodiesel production uses catalytic esterification followed by transesterification with KOH. process. Extracted oil containing 11.19% of high-lipid fatty acids as an acid catalyst Esterify with 80% methanol, 2.5% H2SO4 at 70 °C for 60 min. Esterified Oil vs. Trans Esterification with biodiesel for 120 min at 60 °C using 60% methanol and 0.8% KOH. biodiesel production That's 95.81%. Characteristics of the produced biodiesel such as flash point (145 oC) and acid value (2.7 mg) KOH/g), density (0.870 g/cc), pour point (-12oC) and viscosity (5.79 and 1.2cSt, 40 and 100oC) respectively), etc. are determined. These characteristics are very close to commercial. Biodiesel standard. Renewable leather industry waste can be a potential source of biodiesel. production, protect the environment and increase energy demand.
