Description
Oczyszczanie (rafinacja) olejów mine¬ ralnych, pochodzacych z ropy, z wegla bru¬ natnego, wegla kamiennego i t. d. odbywa sie zazwyczaj w ten sposób, ze surowe de¬ stylaty np. benzyna, nafta lub olej przez dzialanie kwasu siarkowego, a nastepnie lu¬ gu i wymywanie woda pozbawione zostaja asfaltów, cial barwiacych i nienasyconych.Przy tej operacji powstaja duze straty przez porywanie dalszych czesci destylatu.W szczególnosci produkty, zawierajace wieksza ilosc zwiazków nienasyconych np. benzyna krakowa i inne produkty krakowe nie daja sie wyrafinowac, poniewaz przy- tem po czesci sie zamieniaja w ciala zywicz¬ ne.Okazalo sie, ze przez dzialanie cial chlonnych jak np. wegla aktywnego, kolo¬ idalnej krzemionki i tym podobnych na ta¬ kie produkty w formie pary nastepuje oczy¬ szczenie (rafinacja) bez wiekszych strat. Te ciala porowate dzialaja mianowicie czescio¬ wo katalitycznie-kondensujaco1, przez co powstaja weglowodory nasycone, czescio-wo zas wchlaniaja one zwiazki barwne i ta¬ kie o niemilym zapachu.Cialo chlonne przez czas dluzszy nie zmienia swej aktywnosci, a dopiero przy zmniejszeniu sie wlasnosci oczyszczajacych nastepuje regeneracja w sposób znany np. przez wyparowanie para wodna.Okazalo sie równiez, ze najkorzystniej - szem i najekonomiczniejszem jest oczy¬ szczanie weglowodorów tylko wtedy, gdy po zamienieniu ich w pare rozcienczy sie je jakims gazem stalym jak np. wodór, azot, metan, kwas weglowy.Przyklad. Benzyne krakowa ogrzewa sie w zamknietem naczyniu do temperatury wrzenia, a tworzace sie pary benzynowe przepuszcza przez warstwe wegla aktyw¬ nego.Ogrzewanie reguluje sie w ten sposób, azeby w ciagu jednej godziny przez war¬ stwe wegla aktywnego przechodzilo co naj¬ wyzej 5% par benzynowych, które po o- chlodzeniu w odpowiednim chlodniku o- trzymuje sie jako bezbarwna, bezwonna i prawie zupelnie z nasyconych weglowodo¬ rów sie skladajaca benzyne.Do oczyszczania tym sposobem nadaja sie szczególnie takie oleje mineralne, któ¬ rych punkt wrzenia lezy ponizej 350°. PL PLThe purification (refining) of mineral oils derived from petroleum, brown coal, coal, etc. is usually carried out in such a way that crude distillates, e.g. gasoline, kerosene or oil, by the action of sulfuric acid and then The slurry and water leaching are free of asphalts, coloring and unsaturated bodies. In this operation, large losses are incurred by entraining further distillate parts. In particular, products containing a greater amount of unsaturated compounds, e.g. - so they partially turn into resinous bodies. It turned out that by the action of absorbent bodies such as activated carbon, colloidal silica and the like on such products in the form of a vapor, purification (refining) takes place without much precipitate. These porous bodies act in part catalytically-condensing, thus producing saturated hydrocarbons, and in part they absorb colored compounds and those with an unpleasant odor. cleaning agents are regenerated in a manner known e.g. by evaporation of water vapor. It has also turned out that the most advantageous and economical treatment is to purify the hydrocarbons only when, after converting them into steam, they are diluted with a solid gas, e.g. hydrogen, nitrogen, methane, carbonic acid. Cracked gasoline is heated in a sealed vessel to the boiling point, and the gasoline vapors that are formed are passed through the layer of activated carbon. The heating is regulated in such a way that within one hour, at least 5% of the vapor passes through the layer of activated carbon. gasoline, which, after cooling in a suitable chiller, is colorless, odorless and almost entirely of saturated hydrocarbons, which consists of gasoline. Mineral oils with a boiling point below 350 ° are particularly suitable for this purification process. . PL PL
