Continuous Production of Lipase-Catalyzed Biodiesel in a Packed-Bed Reactor: Optimization and Enzyme Reuse Study
An optimal continuous production of biodiesel by methanolysis of soybean oil in a packed-bed reactor was developed using immobilized lipase (Novozym 435) as a catalyst in a tert-butanol solvent system. Response surface methodology (RSM) and Box-Behnken design were employed to evaluate the effects of reaction temperature, flow rate, and substrate molar ratio on the molar conversion of biodiesel....
متن کاملLipase-catalyzed Continuous Ring-opening Polymerization ofe-Caprolactone in a Packed-bed Reactor
A packed-bed reactor (PBR) system was developed for continuous lipase-catalyzed ring-opening polymerization of -caprolactone ( -CL). The parameters affecting the poly( -caprolactone) (PCL) production in the PBR such as residence time, height to diameter (H/D) ratio, and monomer feed concentration were investigated. Monomer conversion of -CL increased with the increase of residence time, reached...
متن کاملProduction of structured lipids by acidolysis of an EPA-enriched fish oil and caprylic acid in a packed bed reactor: analysis of three different operation modes.
Structured triacylglycerols (ST) enriched in eicosapentaenoic acid (EPA) in position 2 of the triacylglycerol (TAG) backbone were synthesized by acidolysis of a commercially available EPA-rich oil (EPAX4510, 40% EPA) and caprylic acid (CA), catalyzed by the 1,3-specific immobilized lipase Lipozyme IM. The reaction was carried out in a packed bed reactor (PBR) operating in two ways: (1) by recir...
متن کاملSTABILITY OF IMMOBILIZED Rhizomucor miehei LIPASE FOR THE SYNTHESIS OF PENTYL OCTANOATE IN A CONTINUOUS PACKED BED BIOREACTOR
The enzymatic synthesis of organic compounds in continuous bioreactors is an efficient way to obtain industrially important chemicals. However, few works have focused on the study of the operational conditions and the bioprocess performance. In this work, the aliphatic ester pentyl octanoate was obtained by direct esterification using a continuous packed bed bioreactor containing the immobilize...
متن کاملKinetic study of lipase-catalyzed glycerolysis of palm olein using Lipozyme TLIM in solvent-free system
Diacylglycerol (DAG) and monoacylglycerol (MAG) are two natural occurring minor components found in most edible fats and oils. These compounds have gained increasing market demand owing to their unique physicochemical properties. Enzymatic glycerolysis in solvent-free system might be a promising approach in producing DAG and MAG-enriched oil. Understanding on glycerolysis mechanism is therefore...
