El cambio climático es un problema mundial que cada vez nos preocupa más a todos. La principal causa del calentamiento global son los gases de efecto invernadero, siendo el CO2 uno de los más importantes. Decenas de Gigatoneladas de este gas son emitidas cada día a la atmósfera. Este trabajo se focaliza en la técnica "Ca-Looping" cuyo objetivo...

The calcium looping (CaL) process, based on the calcination/carbonation of CaCO3 at high temperatures, has emerged in the last years as a potentially low cost technology for CO2 capture. In this work, we show that the application of high intensity sound waves to granular beds of limestone and dolomite in a CaL reactor enhances significantly...

Understanding the flowability of cohesive powders at high temperature is of great importance for many industrial applications where these materials are handled at harsh thermal conditions. For instance, the Calcium-Looping (CaL) process, involving the transport, storage and fluidization of limestone powders at high temperature, is being...

Fine powders are the cornerstone of new energy storage solutions to assist concentrated solar power plants. Though, their ability to behave like fluid can be seriously affected at high temperatures. This work investigates the use of nanosilica in fine limestone (calcium carbonate, CaCO) powders to mitigate the promotion of cohesion forces at...
