Equipments & Methodology

Our laboratories and technical hall are equipped with several reactors for catalyst testing as well as equipment for catalyst preparation and characterization.


Micro Catalyst Bed unit – This PC-controlled unit is used for hydrogenation under high pressure of various compounds. Two liquids simultaneously with a gas such as H2 or N2 can be feed into the fixed-bed reactor of 11 ml (16 cm x 0.85 cm). The unit can be pressured up to 280 bar while with maximum temperature is 450 °C. 

Bench Top Autoclave Reactor – This high pressure stirred laboratory apparatus is used for diverse catalyst research, catalyst characterization, and surface chemistry studies under neutral, reductive or oxidizing atmosphere. The autoclave can be pressured up to 200 bar, the maximum operating temperature is 500 °C.

Down-flow fixed-bed tube reactor - This reactor is used for the treatment of solid materials under high-temperature conditions and the study of their catalytic performance. The flow catalytic unit equipped with: a tubular furnace (a heating zone with the length of 300 mm and the maximum temperature of 1000 °C), gas flow meters and an HPLC pump.

Analytical methods

ICP-OES is used for the determination of metal leaching from catalysts in an organic matrix.

GC machine Agilent 7820A is used for the analysis of reaction products. The GC unit is equipped with an auto-injection system, a capillary column and FID, and controlled by the OpenLAB CDS Workstation.

TPR/TPD/TPO instrument AMI-300 with a TCD and FTIR cell. The unique setup is able to determine catalyst properties such as reducibility or probe acid-base character. Moreover, the catalyst surface could be treated by various organics and their interaction analysed. 

At UCT we have long-lasting and successful cooperation with:
Laboratory for XRF and XRD analysis (S. Randáková, J. Cibulková)
Laboratory for H2-TPR and nitrogen physisorption (M. Lhotka)
Laboratory for TGA-MS (V. Fíla)
Laboratory for AAS analysis (D. Pokorná)
Laboratory for Raman spectroscopy (M. Novotná, L. Lapčák)
Laboratory for ICP analysis at UCT Technopark Kralupy


The catalyst preparation is our main focus and we are able to prepare co-precipitated as well as supported catalysts synthesized via a wide range of techniques. The following calcination and reduction in ovens could be done under different atmospheres.

Co-precipitation apparatus is intended for catalysts preparation under controlled temperature and pH values. The apparatus equipped with: magnetic stirrer with hotplate (maximum temperature is 380 °C, maximum stirring speed is 1.500 rpm), benchtop pH-meter (resolution ± 0.01 pH, maximum temperature is 100 °C) with glass electrode, 2 peristaltic pumps for co-feeding reactants (maximum output is 100 ml/min).
