Abstract:
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.

Claim (Index 7):
A method of preparing an acid gas absorption composition, the method comprising:\n (a) hydrating a starting material to generate an intermediate material comprising calcium hydroxide and having a residual moisture content from 18-27% by weight of the intermediate material, wherein the starting material comprises calcium oxide characterized by a size less than 10 mm, a reactivity to water less than 40\u00b0 C./min; (b) drying the intermediate material to a residual moisture content of less than 2% by weight of the intermediate material, wherein the calcium hydroxide is characterized by a specific surface area of 25-55 m 2 /g and a porous volume less than 0.25 cm 3 /g; (c) milling the intermediate material to at least 90% by weight of the mixture having a size of less than 32 micrometers; and (d) contacting at least a portion of the intermediate material and a heated gaseous stream for a time sufficient to heat the intermediate material to 400-510\u00b0 C. to generate the composition, wherein the composition is characterized by a specific surface area from 40-100 m 2 /g, a porous volume from 0.25-0.50 cm 3 /g, more than 40% by weight of the composition of pores with a diameter from 100-400 Angstroms, and an acid gas mass absorption capacity of at least 4.5 grams acid gas per 100 grams composition.
