HIGHLY ACTIVE SORBENTS AND OXYGEN CARRIERS SUPPORTED BY CALCINED ALUMINA AEROGEL FOR LOW-TEMPERATURE CARBON CAPTURE AND CHEMICAL-LOOPING COMBUSTION OF METHANE

摘要

The invention provides highly reactive nano-sized alumina particlecompositions, including alumina compositions with a BET surface areas on theorder of 2000 m21g. Also disclosed are impregnated alumina supports comprisingmaterials that are metal oxides or carbonates. Methods for the synthesis andfabrication of these compositions are provided, along methods for the use ofthesecompositions as sorbents.
