Energy our elixir of life - where it comes from, where it goes

online lecture 3pm

Moderation: Klaus-Dieter Jany

No life without energy. For millennia, renewable raw materials, hydropower and wind energy have been the only sources of energy for human development. However, the amount of energy available was always limited, despite its increasingly efficient use. This changed dramatically after James Watt's steam engine made it possible to exploit seemingly unlimited coal reserves. Technologies for oil and natural gas production were added later. The excessive use of these Literature has meanwhile changed the composition of the earth's atmosphere in such a way that serious climatic changes must be expected globally. The lecture shows which dimensions have to be mastered in the global conversion of the fossil energy system to a sustainable one again.


Industrial heterogeneous catalysis

online lecture by Ekkehard Schwab on February 15, 2022, 3 p.m.

Moderation: Klaus-Dieter Jany

Heterogeneous catalysts are the backbone of modern petrochemicals. Its successful development requires the close cooperation of a large number of technical and scientific disciplines: inorganic solid-state chemistry, surface science, chemical reaction engineering and, last but not least, solid process engineering for reproducible production on an industrial scale. The aim of every development is a catalyst that leads selectively from the feedstock to the desired product over a period of years, although this can be achieved with very different reactor types. The latter in turn determine the external shape of the catalytic converter. In the course of more than a century of development, a gradual transition from the purely empirical to the increasingly rational catalyst design can be observed. But even today, the complex multi-scale phenomenon of heterogeneous catalysis can only be fully theoretically described for a few simple model reactions.
