The laboratory has an apparatus for determining the textural characteristics of zeolites, micro/mesoporous silicates, mesoporous metal oxides and others. Porous materials are used as catalysts or as carriers of catalytically active phase for elimination of volatile organic compounds from domestic and industrial sources of pollution in processes on the basis of which clean technologies are developed, for processing of petrol fractions and valorization of biomass for the production of biofuels, biopolymers and valuable chemical compounds.
ACTIVITIES
- Determination of the textural characteristics of various porous materials used to develop catalysts for clean technologies;
- Hydrogen chemisorption to characterize catalytic systems of metal-modified porous materials, nano-sized metal oxides and others.
SERVICES
- Characterization of specific surface, volume and size of pores of microporous and mesoporous materials (zeolites, silicates, activated carbon, etc.), differential distribution of micro- and mesopores in size;
- Chemisorption with reactive gases (H2, CO, NH3) for characterization of metal-modified porous materials, nano-sized metal oxides and other porous materials.
EQUIPMENT
Quantachrome Instruments autosorb iQ-MP-AG (Anton Paar brand) has four heating stations up to 1100oC, three measuring stations and a turbomolecular pump reaching a vacuum of 5 x 10-10hPa. It is possible to measure adsorption-desorption isotherms with different gases (N2, CO2, Ar, etc.) as well as to determine the heat of adsorption.
The apparatus provides chemisorption mode operating capabilities (with H2, CO, NH3) with fully automatic operation from in-situ preparation, including switching of the gas used, flow control and furnace control (heating and cooling).
