US09168505B2 Carbon dioxide adsorbents and production methods thereof, carbon dioxide capture module including the same, and methods for separating carbon dioxide using the same 有权
二氧化碳吸附剂及其制备方法，二氧化碳捕集模块及其分离方法

Carbon dioxide adsorbents and production methods thereof, carbon dioxide capture module including the same, and methods for separating carbon dioxide using the same
Abstract:
A carbon dioxide adsorbent may include an amorphous mixed metal oxide including a divalent first metal (M1), a trivalent second metal (M2) different from the divalent first metal (M1), an alkali metal (M3), and an element (A) with an electronegativity of about 2.0 to about 4.0. The alkali metal (M3) may be present in the form of a crystalline halide, an oxide, or a combination thereof. The carbon dioxide adsorbent may also be used in a method of separating carbon dioxide.
Abstract(Chinese):

二氧化碳吸附剂可以包括包含二价第一金属（M1），不同于二价第一金属（M1）的三价第二金属（M2），碱金属（M3）和元素（A）的非晶混合金属氧化物， 电负性为约2.0至约4.0。 碱金属（M3）可以以结晶卤化物，氧化物或其组合的形式存在。 二氧化碳吸附剂也可以用于分离二氧化碳的方法。
