Description
Najdluzszy czas trwania patentu do 24 wrzesnia 1941 r.Przedmiotem niniejszego zgloszenia jest dalsize rozwiniecie sposobu otrzymywania siarki z siarczanów wapniowców, opisane¬ go w Nr 5926, przyczem materjal wyj¬ sciowy rozpuszcza sie w stopionym chlorku sodowym i przez dodanie koksu otrzymuje sie siarczek wapniowca.Wedlug niniejszego wynalazku do sto¬ pionego chlorku sodowego i siarczanów wapniowców przed albo po dodaniu maki koksowej dodaje sie kwas krzemowy lub kwas krzemowy oraz tlenek glinu, najod- powiedniej w postaci dokladnie rozdrob¬ nionej, podatnej do reakcji. Zamiast czyste¬ go kwasu krzemowego i tlenku glinowego mozna równiez stosowac odpowiednie ma- terjaly i surowce, zawierajace kwas ktze- mowy i tlenek glinu w postaci wolnej lub zwiazanej.Okazalo sie mianowicie, ze ten dodatek znacznie ulatwia rozszczepienie siarcza¬ nów wapniowców, pod dzialaniem makikoksowej, na tlenek wapniowca i kwas siar¬ kawy. Jesli wprowadzac koks do masy raa- lemi ilosciami, w miare zuzywania, to dzia¬ lanie dodatku kwasu krzemowego i tlenku glinowego szczególnie sie uwydatnia i wy¬ wiazuje sie gaz bogaty w kwas siarkawy.Juz 5 — 10%-owy dodatek (liczac na wage mieszaniny reakcyjnej) -wystarcza, zeby znacznie zwiekszyc szybkosc rozkladu siar¬ czanów wapniowców, skutkiem czego w cia¬ gu calego procesu stop daje sie latwo mie¬ szac i jest plynny.Ze wzgledu na niewielkie ilosci uzytego kwasu krzemowego i tlenku glinowego nie mozna przyspieszenia reakcji objasnic two¬ rzeniem sie krzemianów wapniowców, wzglednie glinianów tych metali, zreszta w temperatunze stopu soli kuchennej nie two¬ rza sie krzemiany ani gliniany wapniow¬ ców.Jako stopy — rozpuszczalniki dla siar¬ czanów wapniowców oprócz chlorku sodo¬ wego mozna równiez stosowac sole alka- ljów, oraz wapniowców, albo ich miesza¬ nine, wymienione w patencie Nir 5926.W celu bezposredniego otrzymywania siarki zaleca sie jednoczesnie z koksem wprowadzac do stopu pare wodna zapomo- ca wdmuchiwania. W ten sposób otrzymuje sie mieszanine gazów, zawierajaca kwas siarkawy, siarkowodór, tlenek i dwutlenek wegla i przez proste ochlodzenie lub prze¬ prowadzenie tej mieszaniny ponad weglem aktywnym mozna wieksza czesc zwiazków siarkowych otrzymac w postaci siarki pier¬ wiastkowej. PL PLThe longest term of the patent until September 24, 1941. The subject of this application is a further development of the method of obtaining sulfur from calcium sulphates described in No. 5926, whereby the starting material is dissolved in molten sodium chloride and by adding coke, the calcium sulphide is obtained. According to the present invention, silicic acid or silicic acid and alumina are added to the molten sodium chloride and alkaline earth sulphates before or after the addition of cocoa powder, preferably in a finely divided, reactive form. Instead of pure silicic acid and alumina, it is also possible to use suitable materials and raw materials, which contain both acid and alumina in free or bound form. This addition has been shown to significantly facilitate the cleavage of calcium sulphates under the action of macicoxide, calcium oxide and sulfuric acid. If the coke is introduced into the mass in a large amount, depending on consumption, the action of the addition of silicic acid and alumina is particularly enhanced and a gas rich in sulfurous acid is produced. Already 5-10% addition (based on the weight) the reaction mixture) - enough to significantly increase the rate of decomposition of calcium sulphates, so that throughout the process the melt is easy to melt and is liquid. Due to the small amounts of silicic acid and alumina used, the reaction cannot be accelerated explains the formation of calcium silicates or aluminates of these metals, moreover, at the temperature of the melt of the table salt, no silicates or calcium aluminate are formed. As alloys - solvents for calcium sulphates, apart from sodium chloride, it is also possible to use alkali salts - lakes and limestone, or mixtures thereof, mentioned in the patent Nir 5926. In order to obtain the sulfur directly, it is recommended to introduce up to one hundred pu steam by means of blowing. In this way, a gas mixture containing sulfurous acid, hydrogen sulfide, carbon dioxide and carbon dioxide is obtained, and by simply cooling or passing the mixture over activated carbon, the greater part of the sulfur compounds can be obtained in the form of elemental sulfur.
