| titleOfInvention | Process for the preparation of a smoke desulphurisation agent |
| abstract | Removal of sulphur oxides from combustion gases by the dry method using MgO as an absorbent and Fe2O3 as a catalyst is improved by using a natural iron contg. magnesium silicate pref. serpentine subjected to HCl pretreatment and calcined. The pretreatment is carried out with a dil. HCl soln. pref at an elevated temp. until the weight of the undissolved serpentine decreases to 70-35 wt.%. The undissolved residue is filtered off. The filtrate is subjected to spray-calcination, whereby the residue is oxidised to form an oxide mixt. calcined magnesite can be opt. added in a ratio between 1:3 and 3:1. The above absorbent is obtained by inexpensive process from serpentine which is abundant in nature. The absorbent contains the build-in Fe2O3 Catalyst which is necessary for the oxidation of SO2 to obtain MgSO4 as the final product. |
