solutions of the amines 2‐amino‐2‐methyl‐1‐propanol (AMP) or piperazine (PZ) is
described. The captured CO2 is stored as solid NaHCO3, KHCO3, and AMP or PZ
carbamates. Solid NaHCO3 and KHCO3 are decomposed at 200° C and 250° C,
respectively, to regenerate the carbonates for their reuse. In the experiments with AMP or
PZ, the solid carbamates are decomposed at 80° C–110° C to regenerate the free amines …
