Production of specialty chemicals increasingly makes use of the enzyme catalysts in organic solvents, and Novozym 435 (N435) is among most often applied. However, its polymeric skeleton is unstable in many solvents. In this context we report the results...
Mathematical models of the process of air purification from hydrophobic (styrene) or hydrophilic (vinyl acetate, VA) compounds carried out in a co-current trickle-bed bioreactor (TBB) were presented. These models were marked as TSM (two-substrate model),...
Hexagonal channels display promising flow and transfer characteristics, thus they are considered as prospective structured catalyst carriers. While transfer intensity in long channels is rather moderate, it may be greatly enhanced by channel shortening,...
In this study, we present a modulated synthesisnanocrystalline defective UiO-66 metal−organic framework as apotential chloroquine diphosphate (CQ) delivery system. Increas-ing the concentration of hydrochloric acid during the modulatedsynthesis...
In this study red currant was used as a source of pectin. The aim of this study was to investigate the physicochemical properties of obtained polysaccharide, with an emphasis on behaviour in aqueous solutions. Pectin was obtained using water extraction,...
The study of CO2/N2 separation by supported ionic liquid membranes (SILMs) based on polymeric membrane with ceramic support is presented. The SILMs have been developed by impregnation of the ceramic support of commercial polydimethylsiloxane (PDMS) membrane...
Bubble columns are widely used as contacting devices and multiphase reactors in process and chemical industries. Their “baseline” layout involves a vessel wherein the gas phase is injected into a stagnant liquid phase in the form of “dispersed...
A critical review on the improvement of penetration theory is presented in this work. The volumetric liquid-phase mass transfer coefficients kLa in seven different liquids (1-butanol, 2-propanol, anilin, decalin, nitrobenzene, tetralin, and ethylene...
Periodic open cellular structures (POCS) are becoming increasingly popular as catalyst carriers due to favorable properties: mixing flow, intense heat/mass transfer and low flow resistance. Their design and manufacturing are relatively easy and cheap....
The paper presents the research on the new structured catalytic carriers, called streamlined structures. The innovative structures are composed of short triangular channels, the walls of which are similar to an airfoil profile. The structures were made...
A new series of thiophene-based azomethines differing in the core structure was synthesized. The effect of the central core structure in azomethines on the thermal, optical and electrochemical properties was investigated. The obtained compounds exhibited...
This paper presents the kinetics of methanol synthesis from carbon dioxide and hydrogen over a Cu/Zn/Zr/Ga catalyst. Kinetic studies were carried out in a continuous-flow fixed-bed reactor in a temperature range from 433 to 513 K, pressures from 3 to...
