Predicting the packed-bed reactor performance with immobilized microbial lactase
(Elsevier, 2006-12)
A mathematical model for several working conditions was numerically solved to study a fixed bed reactor with a biocatalyst. The effect of bed swelling, mass transfer limitations, axial dispersion, residence times and inlet ...
Enzymatic synthesis of structured lipids from grape seed (Vitis vinifera L.) oil in associated packed bed reactors
(2020-01-01)
Triacylglycerols (TAGs) can be modified to increase the absorption of fatty acids, prevent obesity, and treat fat malabsorption disorders and metabolic diseases. Medium–long–medium (MLM)-type TAGs, which contain medium-chain ...
Effect of biocatalyst swelling on the operation of packed-bed immobilized enzyme bioreactor
(Elsevier, 2008-10)
A general mathematical model was developed for predicting the performance and simulation of a packed-bed immobilized enzyme reactor performing a reaction that follows Michaelis–Menten kinetics with competitive product ...
Applications of immobilized lipases in enzymatic reactors: A review
(2022-03-01)
Lipases are efficient biocatalysts with numerous applications in different industrial sectors, such as pharmaceutical, food, and fine chemistry industries. Enzyme immobilization further extends the applications of lipases ...
Interesterification of milkfat with soybean oil catalysed by Rhizopus oryzae lipase immobilised on SiO(2)-PVA on packed bed reactor
(WILEY-BLACKWELL, 2011)
The potential of the lipase from Rhizopus oryzae immobilised on SiO(2)-PVA to catalyse the interesterification of the milkfat with soybean oil in a packed bed reactor running on continuous mode was evaluated. The reactor ...
Packed-Bed Photocatalytic Reactors. A Packing Structure Model and Its Experimental Validation with Computerized Tomography
(American Chemical Society, 2004-12)
A statistical model is proposed for the description of the spatial structure of a packed bed of spherical-like particles in terms of one- and two-bead distribution functions. This is the first step toward the full modeling ...
Continuous production of xylooligosaccharides in a packed bed reactor with immobilized-stabilized biocatalysts of xylanase from Aspergillus versicolor
(2013-12-30)
The production of xylooligosaccharides (XOS) using a packed-bed enzymatic reactor was studied at lab-scale. For this, a xylanase from Aspergillus versicolor was immobilized on different supports. The optimal derivative was ...

Experimental analysis of heat transfer in packed beds with air flow
(2004-07-21)
Heat-transfer studies were carried out in a packed bed of glass beads, cooled by the wall, through which air percolated. Tube-to-particle diameter ratios (D/dp) ranged from 1.8 to 55, while the air mass flux ranged from ...
