| 成果简介 | NOVELTY - Invention relates to hydrochemical methods of recycling vanadium catalyst wastes obtained during production of sulphuric acid from sulphur combustion gases, from waste gases of ferrous and non-ferrous metallurgy. Processing of spent vanadium catalyst involves leaching with water vapour or an azeotropic mixture of water and sulphuric acid with volume ratio of water: sulphuric acid with concentration of 10-50 wt.% and temperature of 100-150 °C, with subsequent condensation of vapours of vanadium acids in aqueous solutions of sulphuric acid of 10-50 wt.% concentration. USE - Performing operations. ADVANTAGE - Method increases efficiency of the process and simplifies the hardware scheme of the process. 1 cl, 6 ex |
