Biodiesel Synthesis over Mesoporous Solid Acid Catalyst
J. Environ. Nanotechnol., Volume 8, No 3 (2019) pp. 16-23
Abstract
A simple and new hydrothermal method was adopted to synthesize CuAlPO4 and MgAlPO4 catalysts by using Triethylamine as a template. The synthesized catalysts were characterized by using FT-IR, XRD, SEM and BET. These characterization techniques have proved the formation of tetrahedral frameworks of CuAlPO4 and MgAlPO4 catalysts. The biodiesel synthesis reaction has been carried out with ethanol. The experimental conditions like contact time, temperature, mole ratio and catalyst dosage were optimized for maximum conversion. Conversion of biodiesel and selectivity of biodiesel was more on CuAlPO4 than MgAlPO4.
