Abstract: One-stage process results in complete removal of Cl2, COCl2 and HCl from effluent gases produced during the mfr. of Al by reaction of alumina or bauxite with Cl2 in the presence of CO or C. The purification is carried out using a 0.1-30 wt.% FeCl2 soln. having a pH between -0.7 and +1.5 pref. 0-1.0. between room temp. and the boiling point. The spent FeCl2 soln. is pref. regenerated with iron scrap and recycled.

Abstract: Catalyst, contg. V2O5 and alkali sulphate as active materials on a carrier, for oxidn, of SO2 to SO3 with O2, is treated with H2SO4 before first use. Addn of 5-15 wt.% H2SO4 prevents occurrence of harmful high temp. peaks.
