ABSTRACT:
Exemplary carbon dioxide absorbent compositions of the invention incorporate calcium hydroxide, water, and a phosphonic acid or salt thereof. The composition is made into a paste and formed into particles that are conveniently and efficiently processable. When hardened, the particles have excellent carbon dioxide absorbent performance, crush resistance, and pore structure.
