CO2 CONVERSION

TARGET OF THE PROJECT

CO2 Conversion and Reduction

Description of the Application.

Conversion of CO2 into solar fuels is a key technology for developing a sustainable energy economy while global warming issues are simultaneously addressed. So far, CO2 can be reduced either with solar-derived H2 or directly with water, in the near- or long-term respectively.

In both cases, a gas-phase reaction is desirable for scaling the process since it is more practical and economically feasible. Our project aims to use nanomaterials as photocatalysts to achieve a high CO2 conversion.

Currently, we are exploring the hydrogenation -CO2 reaction. For such experiments, we need to have a mix of the reagent gases which is the reason that we acquired the GB100 Series. We carry out the reaction in a continuous mode, consequently, we need a low gas flow of 5 mL/min.

Benefits and Savings.

The gas blender GB100 Series turned out to be a reliable and compact device for diluting the gas sample and generating a controlled low gas flow. With this configuration, the sensor is able to operate in a comfortable range, even when traditional Mass Flow Controllers could not achieve it.

▼ABOUT THE UNIVERSITY

ETH Zurich (Swiss Federal Institute of Technology in Zurich); École polytechnique fédérale de Zurich is a science, technology, engineering and mathematics university in the city of Zürich, Switzerland. Like its sister institution EPFL, it is an integral part of the Swiss Federal Institutes of Technology Domain (ETH Domain) that is directly subordinate to Switzerland’s Federal Department of Economic Affairs, Education and Research. The school was founded by the Swiss Federal Government in 1854 with the stated mission to educate engineers and scientists, serve as a national center of excellence in science and technology and provide a hub for interaction between the scientific community and industry.

▼MAIN BENEFITS

Gas Mixer vs. Mass Flow Controller.

The GAS MIXER channels it’s more compact than typical flow controller meters and can be specifically calibrated on the mixture to be used.

Without MCQ?

3 Mass Flow Controllers with Power control Unit, tubes, NO-Software and different Gas Mixture Cylinders.

Time Savings.

Instead of changing a calibration cylinder for each point, our Gas Mixer uses pure gas allowing the ETH Zürich to set all the desired calibration points in just a few steps.
