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 particle compositions, including alumina compositions with a BET surface areas on the order of 2000 m²/g. Also disclosed are impregnated alumina supports comprising materials that are metal oxides or carbonates. Methods for the synthesis and fabrication of these compositions are provided, along methods for the use of these compositions as sorbents.
