ABSTRACT:
In one embodiment, the method comprises: combining liquid biomass with an alcohol to form a combined liquid stream, introducing the combined liquid stream to a first transesterification reactor between a liquid glycerol outlet and a liquid alkyl ester outlet, reacting the liquid biomass and the alcohol to form liquid glycerol and liquid alkyl ester, and removing a liquid alkyl ester stream from an upper portion of the first transesterification reactor. The combined liquid stream flows upward through the reactor at a rate that is less than a settling velocity of the liquid glycerol.
