A biocatalytic process for producing nitriles — without cyanide

Nitrile compounds (R–N≡N) are important for the manufacturing of fragrances, pharmaceuticals, superglue and chemical-resistant gloves. Currently, such nitrile compounds require the use of highly toxic cyanide in their synthesis. Now, an alternative cyanide-free chemo-enzymatic cascade process is being developed by…

Pilot plant produces climate-friendly cement clinker

Concrete production is responsible for 6–9% of global anthropogenic CO2 emissions. “The largest contribution to that comes from the production of cement, a precursor product,” says Peter Stemmermann from the Institute for Technical Chemistry (ITC) at the Karlsruhe Institute of…

A closed-loop hydrometallurgical process for low-carbon iron processing

Electrification will be a key factor in decarbonizing hard-to-abate sectors, but challenges arise in applications that require very high temperatures, such as steel production. The intense heat requirements for converting iron ore into metal contribute significantly to the CO2 emissions…

A fungus converts cellulose directly into a platform chemical

Conventional bioprocesses use three separate steps to convert cellulose into products, such as bioplastics and biofuels. The consolidated bioprocess (CBP) combines all steps — cellulase production, cellulose hydrolysis and product fermentation — in a single reactor. Using the natural abilities…

CO2-to-methanol conversion improved with catalyst-support ion swap

Researchers at Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) and a team of interdisciplinary scientists tripled the yield of methanol in the catalytic hydrogenation reaction of carbon dioxide by introducing hydrides into the catalyst support material. The researchers…

CO2 captured in stationary energy storage battery

An Oak Ridge National Laboratory (ORNL) team created and tested two different formulations for stationary batteries that could utilize CO2 from industrial sources while storing energy from wind turbines and solar panels. Consisting of two electrodes in a saltwater solution,…

A new reactor system for producing polymers

Traditionally, many polymerization reactions are carried out batchwise in reactor vessels, with the reaction taking place in solution, emulsion or in a melt. This procedure reaches its limits if, for example, the reaction is very exothermic or the viscosity increases…
