Kinetic studies of esterification reaction of maleic anhydride with butan-1-ol, 2-methylpropan-1-ol and butan-2-ol were carried out in a semibatch reactor, in the presence of four acidic catalysts: sulfuric acid, phosphotungstic acid, ion exchange resin...
This chapter aims to summarize aspects of bioreactor technology that have been or could be applied to insect cell cultures with an emphasis on bioreactor design considerations. A novel technique applied to enhance cell density of insect cell culture...
A novel design for a three-channel internal-recirculation type reactor is described. The reactor has an extremely compact design that consists of inlet and outlet channels filled with an inert structured packing on either side of a reactor channel containing...
A new parameter (degree of randomness (DR)) was defined for the identification of the main transition velocities, U trans. The new method reconstructs the time series into multiple state vectors, thus generating non-overlapping vector pairs and then...
The separation of CO2/N2 by supported ionic liquid membranes (SILMs) is presented. SILMs have been developed through impregnation of the ceramic support nanopores of commercial PDMS (polidimethylosiloxane) membranes (made by Pervatech BV) and commercial...
Biocatalysis that produces economically interesting compounds can be carried out by using free enzymes or microbial cells. However, often the cell metabolism does not allow the overproduction or secretion of activated sugars and thus downstream processing...
This work presents experimental and CFD simulation results of heat transfer for water and CuO-water nanofluid flow systems stabilized by capping agents. The experiments were carried out in a helically coiled tube in the range of turbulent flow regime...
Optimization of structured reactors is not without some difficulties due to highly random economic issues. In this study, an entropic approach to optimization is proposed. The model of entropy production in a structured catalytic reactor is introduced...
The objective of this work was to study properties of monolithic CO2 sorbents. The materials were obtained by molecular basket approach with polyethyleneimine (PEI) and grafting method using the silane-modified polyamines (trimethoxysilylpropyl-modified...
The silica monoliths were prepared by a combination of sol-gel synthesis, pore templating, and a process of phase separation. The as-prepared monoliths are characterized by meso- and macroporosity. The pore size significantly differs for each sample...
Commercially available polymeric membrane materials may also show their potential for CO2 capture by the association of the membrane process with other separation techniques in a hybrid system. In the current study, PRISM PA1020/Air Products and UBE...
The use of copper-based binary catalysts, Cu/Zr oxides and Cu/Al oxides, has been examined to produce hydrogen from ethanol in the ethanol steam reforming process. The examined catalysts were compared with non-noble bicomponent catalysts consisting of...
