Continuous production of soybean biodiesel with compressed ethanol in a microtube reactor
This work investigates the production of fatty acid ethyl esters (FAEEs) from the
transesterification of soybean oil in supercritical ethanol in a continuous catalyst-free
process. Experiments were performed in a microtube reactor in the temperature range of
523K to 598K, from 10MPa to 20MPa, varying the oil to ethanol molar ratio from 1: 10 to 1:
40, and evaluating the effects of addition of carbon dioxide as co-solvent. Results showed
that ethyl esters yield obtained in the microtube reactor (inner diameter 0.76 mm) were …

microtube reactor in the temperature range of 523K to 598K, from 10MPa to 20MPa, oil to
ethanol molar ratio from 1: 20 to 1: 40, and co-solvent to substrates mass ratio from 0.05: 1 to
0.2: 1. Results showed that ethyl esters yield obtained increased with increasing addition of …
