The research in the field of chemical engineering has been focused on:
■ renewable energy sources (kinetics of pyrolysis of renewable raw or waste materials, design, operation and modelling of both catalytic and non-catalytic reactors),
■ chromatographic separations of proteins and oligosaccharides: (a) the investigation of equilibrium and kinetic processes of proteins on ion exchangers with grafted polymer layer or on hydrophobic membranes and (b) the optimization of recycle and simulated moving bed chromatography for the separation of fructooligosaccharides; enzymatic transglycosylation of sucrose to fructooligosaccha-rides and lactose to galactooligosaccharides in the area of biocatalytic production of prebiotic compounds,
■ hybrid reaction-separation processes for specialty chemicals, novel extraction methods for organic acids (experimental and mathematical modelling of biotechnological production, reactor/separator system –pervaporation or reactive distillation),
■ modelling of liquid-liquid (equilibrium and mass transfer in extraction processes using phosphonium ionic liquids immobilized on a membrane support) and vapour-liquid (V-L) equillibria (equilibrium and non-equillibrium models of extraction and extractive distillation of alcohol/hydrocarbone mixtures),
■ pollution dispersion (the atmospheric pollution dispersion using CFD modeling),
■ energy savings and exergoeconomic analysis of combined electrici.
