An acid gas absorption composition may generally comprise calcium oxide generally characterized by a specific surface area from 40-100 m 2 / g, a porous volume from 0.25-0.50 cm 3 /g within a pore diameter range up to 1200 Angstroms, more than 40% by weight of the composition of pores having a diameter from 100-400 Angstroms, and an acid gas mass absorption capacity of at least 4.5 grams of acid gas per 100 grams of composition. Methods of making and using the same are also described. |
