Abstract
Simultaneous synthesis and purification of a fatty acid monoester biodiesel fuel from a triacylglycerol feedstock is described. In an exemplary method, the triacylglycerol feedstock is continuously contacted with a catalytic chromatographic bed comprising a first (solid phase) basic catalyst through a first port of a simulated moving bed chromatographic apparatus. A monohydric alcohol and optional second (mobile phase) basic catalyst is continuously contacted with the catalytic chromatographic bed through a second port and pumped in a first direction toward the triacylglycerol feedstock to contact the triacylglycerol in a reaction zone of the catalytic chromatographic bed where the fatty acid monoester and glycerol coproduct are formed. The fatty acid monoester is removed from the reaction zone through a product port of the simulated moving bed apparatus. Segments of the catalytic chromatographic bed are incrementally moved in a second direction, opposite the first direction, and the glycerol is removed from a raffinate port located opposite the product port of the apparatus.
