Iodine oxoacids enhance nucleation of sulfuric acid particles in the atmosphere

Andrea Baccarini, Imad El Haddad, Mihnea Surdu, Lubna Dada, André Welti, Houssni Lamkaddam

The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H2SO4), stabilized by ammonia (NH3). However, in marine and polar regions, NH3 is generally low, and H2SO4 is frequently found together with iodine oxoacids [HIOx, i.e., iodic acid ...

Homogeneous Catalysis for Sustainable Hydrogen Storage in Formic Acid and Alcohols

Paul Joseph Dyson, Gabor Laurenczy, Katerina Stefania Sordakis, Matthias Beller

Hydrogen gas is a storable form of chemical energy that could complement intermittent renewable energy conversion. One of the main disadvantages of hydrogen gas arises from its low density, and therefore, efficient handling and storage methods are key fact ...

Sulfur containing organic compounds in the raw producer gas of wood and grass gasification

Christian Ludwig, Tilman J. Schildhauer

The detailed description of gas streams in biomass gasification plants is necessary for the correct design and operation of these units. Sulfur containing compounds are usually present in biomass gasification gas, since sulfur is typically found in the fee ...

Online elemental analysis of process gases with ICP-OES: A case study on waste wood combustion

Christian Ludwig, Marco Wellinger

A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical syste ...

Conceptual design of a thermo-electrical energy storage system based on heat integration of thermodynamic cycles – Part A: Methodology and base case

François Maréchal

This paper analyses the thermodynamic performance and proposes different energy integration schemes for a methanol absorption based acid gas removal process, namely the Rectisol® process specifically designed for the selective removal of H2S and CO2 from c ...

Hydration, microstructural development and dimensional stability of cementitious materials made of portland cement clinker and fluoroanhydrite

Carolina Prieto Gomez

The production of Portland cement accounts for 5 to 8% of the global anthropogenic CO2 emissions. In the past years, the cement industry has attempted to reduce this contribution by the use of mineral additions on the cement or in the concrete mix. The typ ...
