Plant and process engineering

Every year the chemical industry produces around 100 million tonnes of methanol. However, the production of this important basic chemical is based on fossil raw materials and causes high CO₂ emissions. The exact opposite would be conceivable: Methanol can also be produced from green hydrogen and carbon dioxide. But process requirements for producing green methanol on an industrial scale have been little researched to date. The project "Power-to-Methanol - Grünes Methanol", funded by the Federal Ministry of Economics, wants to change this.

On average, each German buys around 60 items of clothing a year - not counting underwear. Conventional production of one kilogram of cotton consumes up to 10,000 liters of water. The high water consumption is one of many reasons why the textile industry is considering a recycling economy. So far, however, with the exception of some synthetic fibers, textiles have been based exclusively on virgin fibers.

Cool, refreshing drinks are always welcome during the summer time. But many customers shy away from high sugar contents and too many chemical ingredients in commercially available sports drinks. Therefore, researchers at the Fraunhofer Institute for Process Engineering and Packaging IVV in Freising developed a novel, protein-rich summer drink made from sweet lupins. The production of this new drink should be feasible for any brewery. The technique was developed in cooperation with the Technical University Munich as well as partners from industry.

Our bodies, windows or plastic bottles – all of them are made up of different molecules. The big difference however: while the molecules in the human body or other living organisms are in constant exchange with their surroundings, artificially produced material is not. This in turn directly affects their ability to break down after being used.

The vanadium-dependent nitrogenase is an enzyme that catalyses two important processes: On the one hand it converts atmospheric nitrogen (N₂) to ammonia, on the other hand it reduces carbon monoxide (CO) to hydrocarbons. Today, both reactions are run on a big scale by chemical catalyses to produce ammonia and fuels for industry. In additon, ammonia is used as synthetic fertilizer to ensure the food production for at least half of the world’s population.
