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.

In our work, biodiesel was prepared from Tra fat by methanolysis reaction using activated calcium oxide as solid base catalyst. Effects of various process parameters on biodiesel production such as molar ratio of methanol to fat, catalyst concentration, temperature and time of reaction and the active mechanism of CaO catalyst for the transesterification reaction were investigated. The results show that CaO has strong basicity and high catalytic activity as a heterogeneous solid base catalyst and the transesterification reaction takes place on basic sites of calcium diglyceroxide formed due to the reaction between Cao and the by-produced glycerol. The biodiesel yield achieves 92.95 % at 60°C, 90 minutes, 8:1 molar ratio of fat to methanol, and 6 % CaO catalyst. Important fuel properties of the produced biodiesel meet the specifications of ASTM D 6751 biodiesel standard.
