Equipment
Operando DRIFTS/Ssitka-Drifts
FTIR (Thermo Nicolet 6700) with DTGS and MCT detectors equipped with a Smart Collector accesory with Dual environmental chamber for DRIFTS analyses under reaction conditions.
The effluent gases are quantified with a OMNIstar mass spectrometer.
A low dead volume cell (Harrick) is used for SSITKA-DRIFTS measurements.
In-Situ FTIR/ Operando-FTIR
Reactor Setup 1
Fixed bed reactor capable of operation at medium pressure. It is used for CO2 hydrogenation to methanol and methanol oxidation reaction. Reactants and products of the reaction are analyzed online with a gas chromatograph (SRI 8610C) that separates the different gases using a capillary column and three packed columns. The system is equipped with a thermal conductivity detector, a flame ionization detector and a flame ionization detector provided with a methanizer.
Reactor SETUp 2
Fixed bed reactor capable of operation at medium pressure (up to 10 bar). It is used for CO2 hydrogenation to methanol and olefins. Reactants and products of the reaction are analyzed online with a gas chromatograph (SRI 8610C) that separates the different gases using a capillary column and three packed columns. The system is equipped with a thermal conductivity detector, a flame ionization detector and a flame ionization detector provided with a methanizer.The experimental setup has automated mass controllers.

Pretreatment unit
Fixed bed reactor used for the pretreatment of materials by oxidation/reduction.
Furnaces
We have two ovens for thermal treatment of our materials: one enables the calcination in static air at temperatures up to 1100°C and the other is a tubular furnace which permits the control of the type of gas and flow as well as the temperature (up to 1400°C).
