Optimization of catalyst performance to increase efficiency of methanol production
Many types of catalysts have been well known for decades, but the fundamental understanding as to why they work so well is still not quite clear. Without this understanding, an even more efficient catalyst cannot be developed, which is needed to reduce the global energy demand. Copper-zinc-alumina (CZA) is a popular catalyst and has been used for about 100 years, as it facilitates the production of the important chemical building block methanol, a molecule that enables the storage of hydrogen in a manner that minimizes negative impact on the carbon-dioxide footprint. Until 2021, scientists debated over the reason why the catalyst works so well. Understanding the reason behind this is vital in order to further develop even better ones. The copper-zinc-alumina (CZA) catalyst is assessed at the Laboratory for catalysis and sustainable chemistry (LSK) of the Paul Scherrer Institute.
Asthma: diagnosis in a single breath
PSI is involved in the development of a breath test that can be used to diagnose asthma. Imad El Haddad explains why such a test could be extremely useful – especially for children.
E-fuels and electrification as complementary approaches to achieve climate target
Sustainable, synthetic fuels, so-called e-fuels, can help reduce CO₂ emissions. For their production, electricity from renewable sources is required in order to allow for a close to CO₂-neutral balance. The availability of electricity from renewable sources, which ensures the climate benefits of e-fuels, is currently still limited. “Especially in order to produce on a larger scale, a lot of renewable electricity is needed,” explains Christian Bauer, researcher at the Laboratory for Energy Systems Analysis (LEA) at PSI.
Unravelling the catalyst aging phenomena in vehicle emission control.
PSI has collaborated with catalyst and engine manufacturers to understand the aging phenomena of emission control catalysts. To this end, a diesel oxidation catalyst with a relevant mileage was carefully analysed; the results suggest that a complex combination of poisoning and thermal sintering is the cause of deactivation during driving. A reactor setup was then developed to simulate poisoning and sintering effects for prediction of catalyst durability in time and cost effective manner.
