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.
