ChemCatChem, Volume 17, Issue 12, June 23, 2025.Hydrogen can be added to a solid solution of rutile oxides (RuxTi1‐xO2 and IrxTi1‐xO2) at a concentration of 20–30 at% by exposing it to hydrogen at a temperature of 150–200°C. This has been shown to dramatically increase the catalytic activity of oxidation reactions, such as the combustion of propane (thermal catalysis) and the evolution of oxygen in ...

Fuel Processing Technology, 1999 Storage, shipment, handling, as well as drying and calcination of petroleum cokes might create serious health risks. This material should be processed and handled with care not only because of the excessive dust emissions it causes, but also because it may emit hazardous and carcinogenic volatile compounds.
