Description
Przy wyrobie kwasu siarkowego spo¬ sobem stykowym nie udawalo sie dotych¬ czas zastapic drogiej platyny innym ta¬ nim, równie skutecznym katalizatorem, zwlaszcza w wielkim przemysle. Posród licznych projektów w tym kierunku byl takze wspomniany kwas wanadowy, ten jednakze we wszystkich dotychczas opi¬ sywanych postaciach jest daleko mniej skuteczny niz platyna.Niespodziewanie znaleziono obecnie w kwasie wanadowym srodek, którego skutecznosc jest bliska lub równa sku¬ tecznosci platyny, tak, ze zastosowanie tego kwasu w technice przy wyrobie kwasu siarkowego sposobem kontakto¬ wym jest zapewnione, jezeli uzywac go w obecnosci przenosników w najwyz¬ szym stopniu rozdrobnionych. Takim przenosnikiem jest np. pumeks, którego czasteczki maja stosowna srednice okolo 20 [i. Kwas wanadowy moze byc osa¬ dzony na takim przenosniku, z nadajace¬ go sie do tego roztworu lub zwiazku sam lub z drugiem, ewentualnie tez ka¬ talitycznie dzialajacem, cialem, albo tez moze byc poprostu zmieszany z przeno¬ snikiem; mieszanina wtedy specjalnie ura¬ bia sie z dodatkiem srodków przyspiesza¬ jacych przylgnienie lub bez nich.Przyklad I. 200 czesci wysziamowanego, sprosz¬ kowanego dokladnie pumeksu, o wielkosci ziarna mniej wiecej Ijjl, miesza sie sta¬ rannie z 14 czesciami wanadynianu amo¬ nu, urabia sie ziarnisto i ogrzewa do 440°, w. celu wydalenia amoniaku i zle¬ pienia czasteczek, poczern tak otrzymana mieszanina napelnia sie piece kontaktowe.Przy pomocy tej masy kontaktowej osia¬ ga sie przy zwyklej praktycznie stoso¬ wanej szybkosci gazu, wydajnosc do 96% i wiecej. Zamiast sproszkowanego pu¬ meksu mozna uzywac i innych przeno¬ sników.Przyklad II. 316 czesci wyzarzonej lub niewyza- rzonej ziemi okrzemkowej zagniata sie z wodnym roztworem 50 czesci wanady- nianu amonu i, np. 56 — 72 czesciam1 lugu potasowego lub jakiejs soli alkalicz¬ nej, lub tez np., z roztworem 113 czesci, zawierajacego wode krystaliczna, wana¬ dy ni anu potasu. Wyparowuje sie nastep¬ nie tyle wody, aby masa stala sie ziar-' nista, wypelnia sie nia piec i ogrzewa przy 480° gazami z pod paleniska, a ewentualnie jeszcze jakis czas w stru¬ mieniu powietrza, poczem masa staje sie zdatna do uzytku. Zamiast ziemi okrzem¬ kowej mozna tez uzywac kwasu krze¬ mowego, straconego kwasem solnym ze szkla wodnego i przemytego, albo tez mieszaniny obu tych cial z domieszka maczki pumeksowej, lub bez domieszki.Zastosowac tez mozna dwutlenek cyny (kwas cynowy). Podane stosunki ilo¬ sciowe moga byc w szerokich granicach zmieniane. PLIn the production of sulfuric acid by the contact method, it has not been possible to replace the expensive platinum with another cheap, equally effective catalyst, especially in large industry. Among the numerous projects in this direction was also the aforementioned vanadic acid, which, however, in all the forms described so far is far less effective than platinum. Surprisingly, vanadic acid has now been found to contain an agent whose effectiveness is close to or equal to that of platinum, so that the use of this acid in the art for the production of sulfuric acid by the contact method is ensured if it is used in the presence of highly comminuted conveyors. Such a conveyor is, for example, pumice, the particles of which have an appropriate diameter of about 20 [and]. Vanadic acid may be deposited on such a carrier, either from a suitable solution or in a relationship alone or with the other, possibly also with a catalytically acting body, or it may be simply mixed with the conveyor; the mixture is then specially formulated with or without the addition of adhesion promoters. Example I. 200 parts of a fine, powdered, finely pumice stone, about the size of a grain size of about 1, is mixed carefully with 14 parts of ammonium vanadate , is granulated and heated to 440 °, in order to expel the ammonia and fuse the particles, the blackened mixture thus obtained is filled with contact furnaces. With the help of this contact mass, at the usual practically used gas velocity, a yield 96% and more. Other conveyors may be used instead of powdered puree. Example II. 316 parts of an annealed or unfamiliar diatomaceous earth are kneaded with an aqueous solution of 50 parts of ammonium vanadate and, for example, 56 - 72 parts of potassium liquor or some alkaline salt, or also, for example, with a solution of 113 parts, containing crystalline water , vanadium of potassium. Thereafter, enough water is evaporated to make the mass granular, the furnace fills up and heated at 480 ° with gases from under the furnace, and possibly some time in the air stream, and the mass becomes usable. Instead of diatomaceous earth, it is also possible to use silicic acid, lost with hydrochloric acid from water glass and washed, or a mixture of both with an admixture of pumice flour, or without admixture. Tin dioxide (tin acid) may also be used. The stated quantitative ratios can be varied within wide limits. PL
