2013-1-1 The addition of quicklime to wet coal slurry influences the process in many ways: First comes the formation of calcium hydroxide, which practically means dehydration of slurry and adhesive bonding of grains: [3.1] CaO + H 2 O = Ca OH 2. Then the carbonization reaction occurs, leading to hardening of the agglomerate structure: [3.2] Ca OH 2 + CO 2 = CaCO 3 + H 2 O
