摘要：NOVELTY - A potassium-doped core-shell composite molecular sieve is obtained by crystallizing a core molecular sieve N and a shell molecular sieve S, and performing ion-exchange process with potassium salt. USE - Potassium-doped core-shell composite molecular sieve used for selectively adsorbing gas e.g. carbon dioxide gas (all claimed). ADVANTAGE - The potassium-doped core-shell composite molecular sieve has excellent adsorption capacity and adsorption selectivity with respect to carbon dioxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage of potassium-doped core-shell composite molecular sieve for selectively adsorbing gas.
