Biodiesel was produced from Canola, soybean and Jatropha oils combined methanol using continuously recycled membrane reactor. The membrane served to react and separate the unreacted oil from the product stream, producing high-purity fatty acid methyl ester (FAME). Two ceramic tubular membranes having different nominal pore sizes of 0.2 and 0.5 ${mu}m$ were used. Permeate was observed at 0.5, 1.0 and 2.0 bar with a given flow rate, respectively. The permeate flux for 0.2 ${mu}m$ membrane at 0.5 bar and 400 mL/min flow rate was 15 L/$m^2{cdot}hr$. Also FAME content in permeate was the highest at 0.5 bar, and decreased with increasing operating pressure.
