Abstract Methyl ester of fatty acids, derived from vegetable oils or animal fats are known as biodiesel. The most common method of biodiesel production is transesterification (alcoholysis) of oil (triglycerides) with methanol in the presence of a catalyst which gives biodiesel (fatty acid methyl esters, FAME) and glycerol (by product). In this work, an environmentally benign process for the methanolysis of neem oil to methyl esters using Mg–Al nano hydrotalcites as solid base catalysts in a heterogeneous manner was developed. The effect of the reaction temperature, reaction time, catalyst amount, and methanol /oil molar ratio on the Mg-Al nano hydrotalcite was analyzed. The nano catalysts were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM). Biodiesel produced from the neem oil by using Mg-Al nano hydrotalcite catalyst was analyzed by gas chromatography.

Calcium rich solid base catalyst was synthesized from local waste carbide lime and its catalytic performance was evaluated via biodiesel production. Carbide lime waste was used to produce CLW-I and CLW-II solid base catalyst using different preparation methods. Characterization including base strength analysis, scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) were investigated. Catalytic strength was examined by deploying the solid base catalysts for transesterification reaction of palm oil. Fourier Transform Infra-red (FTIR) was used to analyze the presence of ester group in biodiesel. The yield of biodiesel conversion was calculated based on the mass of biodiesel and glycerol. The highest biodiesel conversion rate of 75.30% was achieved by CLW-I solid base catalyst at 9% loading. The good catalytic performance of carbide lime waste derived solid base catalysts proves that it has high potential to replace the usage of conventional catalyst in the biodiesel industry.
