Research

In times of global warming and where CO2-emissions are discussed a lot, the reusage,

capturing or storage of CO2 becomes more and more attractive and important.

Therefore forging CO2 into products of higher value is a desirable way to go.

Industrially methanol is produced out of syngas (CO2/CO/H2) originating from fossil

sources. Greener approaches try to recycle waste CO2 from industrial plants and H2

generated through electrolysis by electrcity overproduction of renewable energy power

plants. Methanol can be used as a replacement for gasoline but Methanol itself is toxic

and delivers only a low market value. This puts Dimethylether (DME) into the focus of

my work. As DME is non-toxic, non-carcinogenic, non-corrosive and inherits a higher

market value,it clearly surpasses pure methanol as a goal chemical for CO2 hydrogenation.

DME is usually made by dehydration of already produced methanol.

My  approach is the one-step DME synthesis through CO2 hydrogenation.

This route uses a bifunctional catalyst system consisting out of a methanol catalyst

(Cu/ZnO/ZrO2 combined with an acidic catalyst for dehydration (s. Fig. 1). Methanol is

produced and  in-situ converted into DME, therefore completing the synthesis in one single step.

The  optimization of the synthesis and finding new environmetally friendly and

sustainable  catalysts are key goals of my work.
