Facilities for catalytic studies

The set-up for the catalytic activity measurements

The experimental set-up is used in the catalysts activity, selectivity and yield studies. The temperature can be raised up to 900°C. Analyses are done with Gasmet(TM) FTIR-analyzer and by chemiluminescence based oxygen analyzer. The equipment is partially automatized and controlled by LabView software.

 

Micromeritics ASAP2020

The ASAP2020 surface analyser for BET-surface area, pore size and volume as well as dispersion studies. The equipment is used in characterisation of catalysts specific surface area, pore size and volume by N2 adsorption at -195°C. It can use also to determine the precious metal group metals dispersion by CO or H2 chemisorption.

 

Catalytic oxidation equipment for sulphur-containing VOCs

The set-up can be used in conventional catalyst testing experimets such as in light-off, activity and ageing experiments. The system can be modified easily for other purposes as well. Possibility to feed gases and liquids. The analyses are done by continuous gas chromatograph (detectors: FID and FPD).

 

Catalytic oxidation equipment for chlorine-containing VOCs

The structural materials of the set-up stand corrosive conditions. The equipment is designed for light-off, activity and ageing tests. Due to the materials, the maximum operating temperature is 600°C. The possibility to feed multiple gases and liquids is available. Analyses are done by gas-FTIR.

 

Set-up for catalysts ageing studies

The set-up for catalysts deactivation studies. With the apparatus the catalysts can be poisoned or aged by various harmful componets such as sulphur, phosphorus, and others, to study the effects on the catalyst activity.

 

Photoreactor

An annular-type batch photoreactor made from Teflon for liquid phase studies. The UV lamp is placed inside the reactor into a quartz glass tube. The reactor volume is approximately one liter. The mixing of the solution is provided by a magnetic stirrer. The photocatalyst can be used either suspended or immobilized.

 

Equipment for liquid phase photocatalysis

The set-up is used in photocatalytic studies in liquid phase. The quartz glass reactor is surrounded by six irradiation sources which are changeable (visible light, UV-A and UV-B). The reactor can be utilized e.g. for purification of organic waste from water and hydrogen production from water-ethanol mixture. The equipment is connected to H2 analyzer.

 

Equipment for gas phase photocatalysis

A laboratory scale photocatalytic equipment for gas-phase studies. The reactor can be exposed to various kinds of gas mixtures. The product gas formed in the reaction is analyzed with a FTIR gas analyzer, O2 analyzer and H2 analyzer. The reactor surrounded by six irradiation sources (visible light, UV-A or UV-B) is cooled down by an air flow.
