W me¬ todach tych utlenia sie dwutlenek siarki np. za pomoca tlenków azotu, tlenu powietrza przy równoczesnym uzyciu katalizatorów.Sposób wedlug wynalazku upraszcza proces technologiczny i umozliwia wykorzystanie ga¬ zów ubogich w dwutlenek siarki.Sposób wedlug wynalazku polega na elektro¬ litycznym utlenianiu dwutlenku siarki, znaj¬ dujacym sie w gazie i pochlanianiu trójtlenku siarki przez kwas siarkowy. Proces zachodzi w naczyniu elektrolitycznym, w którym anoda i katoda 'zanurzone sa w kwasie siarkowym.Przestrzen pomiedzy elektrodami oddziela po¬ rowata przepona.*) Wlasciciel patentu oswiadczyl, iz twórca wynalazku jest -mgr inz. Juliusz Wesolowski.Dwutlenek siarki na anodzie ulega latwo utlenieniu tlenem molekularnym lub powsta¬ jacym na anodzie ozonem wedlug reakcji 3 S02 + 03 -+ 3 S03.Jednoczesnie zachodzi absorpcja tworzacego sie trójtlenku siarki w roztworze kwasu siar¬ kowego.Anoda jest chlodzona gazem przechodzacym przez roztwór oraz dodatkowa chlodnice.Równoczesnie z utlenianiem dwutlenku siar¬ ki na anodzie, na katodzie powstaje wodór, który jest produktem ubocznym i moze byc uzyty np. do produkcji amoniaku.Do utleniania mozna stasowac gazy o dowol¬ nym stezeniu dwutlenku siarkL W celu uzyskania lepszej wydajnosci procesu mozna dodawac do roztworu katalizatory spel¬ niajace role przenosników tlenu, np. zwiazki zelaza lub manganu. PLPublished on December 10, 1959 mousse * LIBRARY Ufildu Patentowa ** POLSKIEJ RZECZYPOLITEJ PEOPLEJ PATENT DESCRIPTION No. 42514 Poznanskie Zaklady Naicozóir Fosforomych *) Lubon, Poland KL 12 i, 21 The method of producing sulfuric acid The patent lasts from March 15, 1958. a number of methods for producing sulfuric acid from sulfur dioxide. In these methods, sulfur dioxide is oxidized, for example, with nitrogen oxides, air oxygen with the simultaneous use of catalysts. The method according to the invention simplifies the technological process and enables the use of gases poor in sulfur dioxide. The method according to the invention consists in the electrolytic oxidation of dioxide. sulfur contained in the gas and sulfur trioxide absorption by sulfuric acid. The process takes place in an electrolytic vessel in which the anode and cathode are immersed in sulfuric acid. The space between the electrodes is separated by a porous diaphragm. *) The owner of the patent stated that the inventor is - M.Sc. Juliusz Wesolowski. Sulfur dioxide on the anode is easily subject to Oxidation with molecular oxygen or ozone formed on the anode according to the reaction 3 SO2 + 03 - +3 SO3. Simultaneously, absorption of the sulfur trioxide formed in the sulfuric acid solution takes place. The anode is cooled with gas passing through the solution and additional cooler. Simultaneously with oxidation of the dioxide. sulfur on the anode, hydrogen is formed on the cathode, which is a by-product and can be used, for example, for the production of ammonia. For oxidation, gases of any concentration of sulfur dioxide can be used. For better process efficiency, catalysts can be added to the solution acting as oxygen carriers, e.g. iron or manganese compounds. PL
