Preparation of Diacylglycerol-enriched Rice Bran Oil by Lipase-catalyzed Deacidification in Packed-bed Reactors by Continuous Dehydration

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....

Solution of Noncatalytic Packed Bed Reactors Equations by Finite Element Method

Investigating the Batch and Continuous Transesterification of Linseed Oil by Using a Alkaline Heterogeneous Catalyst in a Packed Bed Reactor

Both the continuous and batch transesterification of linseed oil were examined in order to maximize the fatty acid methyl esters (FAME) yield. The continuous process was conducted in a packed bed reactor using calcium oxide as a heterogeneous catalyst. In addition, the impact of two variables, namely the molar ratio of methanol to oil and the flow rate (ml/min), on the FAME yield were stu...

Lipase-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...

Cholesterol-Lowering by Rice Bran and Rice Bran Oil Unsaponifiable Matter in Hamsters

Unsaponfiable matter (U) was prepared from both raw and extrusion stabilized (130'C) rice bran and tested for cholesterol-lowering activity in hamsters by addition to diets containing cellulose, raw rice bran, or stabilized rice bran at either the level found in the rice bran diet (0.4%, 1X) or twice that level (2X). All diets contained 0.3% cholesterol, 10% total dietary fiber, 10.1% fat, and ...
