    Abstract

    Conversion of high free fatty acid (FFA) feedstock (94.4%) to biodiesel with undetectable FFA content is effective using room temperature vortex fluidic flow chemistry, with the conversion taking <1 minute residence time, using dramatically less methanol and acid catalyst compared to other processes. Optimum conditions are 1:6 volumetric ratio of oil feedstock to methanol and 0.2 molar equivalents of H2SO4 catalyst loading, for a combined flow rate of 3.50 mL min-1 in a 17.7 mm internal diameter tube rotating at 7500 rpm. This work furthers the viability of using high FFA content feedstocks for biodiesel production.
