ASSISTED CARBON-DIOXIDE-ADSORPTION METHOD

摘要

The subject matter of the present invention is a CO2-adsorption method that consists in passing a stream of gas with a specific CO2 concentration through a powder bed arranged on a porous plate in a fluidization chamber, the powder bed comprising at least one powder selected from ultrafine powders that comprise primary particles with a typical size of between 1 and 100 nm, and simultaneously subjecting the powder bed to an agitation treatment in combination with an electric field in order to reduce the effect of cohesion between said particles and to destabilize the formation of channels and bubbles. The technical invention relates to the general area of chemical engineering. In particular, the invention would be used in gas-filtration processes. A method is proposed that may be used to stimulate CO2 adsorption by means of the assisted fluidization of metal oxide nanoparticles.
