OSTI ID:921633
- Morgantown, WV
A process for making a granular sorbent to capture carbon dioxide from gas streams comprising homogeneously mixing an alkali metal oxide, alkali metal hydroxide, alkaline earth metal oxide, alkaline earth metal hydroxide, alkali titanate, alkali zirconate, alkali silicate and combinations thereof with a binder selected from the group consisting of sodium ortho silicate, calcium sulfate dihydrate (CaSO.sub.4.2H.sub.2O), alkali silicates, calcium aluminate, bentonite, inorganic clays and organic clays and combinations thereof and water; drying the mixture and placing the sorbent in a container permeable to a gas stream.
