Abstract
(A) In the prodn. of reactive calcium hydroxide for (waste) gas purificn., the novelty is that reactivity increasing materials and/or noxious material-binding materials and/or catalytically acting materials are added prior to slaking, during slaking, to the water required for slaking and/or after slaking. (B) Use of the calcium hydro produced by process (A), for sepn. of acidic noxious materials and/or heavy metals and/or NOx and/or CO and/or organic materials from (waste) gases, is also claimed. (C) Purificn. of (waste) gases, to remove acidic gases (e.g. HCl, HF, SO2 and HCN), NOx, (chlorinated) hydrocarbons, organic cpds. and volatile heavy metals (e.g. Hg, As, Sb, Cd and Tl), comprises mixing the gases with the calcium hydroxide produced by process (A), at 20-1200 deg.C and then sepg. the solids in dust precipitators.
