In
biodiesel production via transesterification, after removing glycerol from
crude biodiesel, purification process must be performed before using biodiesel
as a fuel that meets the EN 14214 standard. In the literature, various
processes are presented for purification of biodiesel however; dry and wet
washing methods are mostly recommended because of their higher efficiencies and
easier applicabilities. In this study, methyl esters (biodiesel) derived from
waste frying oil (WFO) and sunflower oil were generated using
transesterification technique in the presence of KOH and methanol in a novel
microwave assisted biodiesel reactor. For purification of crude biodiesel, two
different methods; washing with distilled water as wet washing, and with
magnesol as dry washing were carried out and compared. According to the
results, dry washing method improved biodiesel yield and ester content, it also
reduced the purification process time considerably
