The research group's area of activity focuses on heterogeneous catalysis, sorption processes and thermochemical conversion of waste to fuel fractions. Renewable energy sources and computer modeling of bioprocesses are also addressed.
The obtained catalysts are analyzed using the following methods: phase analysis by XRD, characterization of the porous system by nitrogen sorption at 77 K, surface analysis by SEM/EDS, DSC, TPR-H2, TPD-NH3, TPD-CO2, spectroscopy UV-Vis-DR.
The work carried out on sorbents is aimed at improving existing and creating new sorption systems for wastewater/rainwater treatment and selective gas purification processes. The Group has experience in the preparation of activated carbons from coal and biomass. The prepared materials are analyzed for their porous structure, the presence of surface chemical groups (FT-IR spectroscopy), and characterization of their surfaces (SEM/EDS). The obtained sorbents are tested in static and dynamic adsorption systems, and their performance is evaluated using UV-Vis spectrophotometer, and chromatographic methods, including GC-MS and HPLC-UV analysis.
Thermochemical conversion of waste (biomass and industrial waste including, for example, waste polymers, automobile tire grinding) is carried out by non-catalytic and catalytic pyrolysis in a solid bed. The processes are aimed at producing liquid fuel fractions. Raw materials for the pyrolysis process are analyzed by the following methods: calorific value, chlorine/sulfur content, moisture content, volatile parts, ash, TGA. Analysis of the resulting liquid fractions includes their full characterization as potential fuel.
The team received on January 30, 2023, the 1st degree award of the Scientific and Technical Association (NOT) "For outstanding achievements in the field of technology" in the Competition of the Wroclaw FSNT NOT Council for the work "Ecological, energy-saving, with continuous operation, grain and oilseed dryer."
