High-purity fatty acid methyl ester (FAME) was produced from different lipids, such as soybean oil, canola oil, a hydrogenated palm oil/palm oil blend, yellow grease, and brown grease, combined with methanol using a continuous membrane reactor. The membrane reactor combines reaction and separation in a single unit, provides continuous mixing of raw materials, and maintains a high molar ratio of methanol to lipid in the reaction loop while maintaining two phases during the reaction. It was demonstrated that the membrane reactor can be operated using a very broad range of feedstocks at highly similar operating conditions to produce FAME. The total glycerine and free glycerine contents of the FAME produced were below the ASTM D6751 standard after a single reaction step. Under essentially the same reaction conditions, a conventional batch reaction was not able to achieve the same degree of FAME purity. The effect of the fatty acid composition of the lipid feedstocks on the FAME purity was also shown. It was demonstrated that, due to the fatty acid composition, FAME from virgin soybean oil and virgin canola oil was produced in the membrane reactor within ASTM specifications even without a water washing step.
