Abstract

Many processes using heterogeneous catalyst, enzymatic catalyst, and supercritical alcohol for biodiesel production have been reported, but the current industrial process has been operated batch-wise using the conventional homogeneous alkali catalyst. A novel process using both cation- and anion-exchange resin catalysts permits the continuous production of high-quality fatty acid esters that meet the specification of international biodiesel standards without needing upstream and downstream processing. An automated, pilot-scale process that produces biodiesel from cheaper multi-feedstocks with free fatty acid contents up to 100 wt% has successfully been in operation for over 3 years. This will be an economically feasible process for continuous biodiesel production.
