Research Interests

The domain of specialization is Experimental, Simulation and Modulation in Chemical Engineering for studying Adsorption Processes for gas separation and storage (natural gas and its odorants, n-C1-C4, CO2, N2, He). The research is mainly focused on experimental, modelling and simulation of gas separation processes by pressure swing adsorption, simulated moving-bed and membrane technologies. The experimental research is supported by adsorption kinetics and equilibrium methods, and spectroscopy techniques applied in a wide range of (P, T) operating conditions. New materials and alternative fluids are also included in the research interests.
