In the recent past, society has become increasingly aware of the environmental impact of political and corporate action. Hence, several industrial sectors are currently undergoing a transition to more sustainable products and processes. Sustainable production processes for C2‐C4 alcohols can help to decrease the environmental impacts of large downs...

The invention relates to a system assembly for steel production with a blast furnace (1) for the production of pig iron, a converter steelworks (2) for the production of crude steel, a composite pipe system (3) for gases that occur during the production of pig iron and / or the production of crude steel, one to the composite pipe system (3 ) connec...

The invention relates to a system assembly for steel production with a blast furnace (1) for the production of pig iron, a converter steelworks (2) for the production of crude steel, a gas pipe system (3) for gases that are produced during the production of pig iron and / or the production of crude steel, and a chemical plant connected to the gas p...

Cu‐Co‐based catalysts provide promising systems for higher alcohol synthesis (HAS) due to a synergistic dual‐site mechanism. Bimetallic Cu‐Co (alloy) nanoparticles are assumed to be the active sites, but cobalt carbide (Co2C) forming under reaction conditions also seems to influence the formation of C2+OH. Na‐doped Co‐modified Cu/ZnO/Al2O3 is appli...

The invention relates to a plant complex for steelmaking with a blast furnace (1) for pig iron production, a converter steelworks (2) for crude steel production, a gas line system for gases resulting from pig iron production and / or crude steel production, and a power plant (3) for power generation. The power plant (3) is designed as a gas turbine...

Growing meat consumption over the past centuries has caused higher amounts of animal by­products. As a consequence of the BSE crisis, established treatments are either not allowed anymore or too expensive. Because of their high protein content, animal by­products, such as animal meals, could be used as low­cost nitrogen sources in fermentation medi...
