Description

Verfahren zur katalytischen Spaltung von Kohlenwasserstoffölen Es =ist bekannt, bei der Spaltung höher siedender Kohlenwasserstoffe in niedriger siedende Kieselsäure als Katalysator zu verwenden.Process for the catalytic cracking of hydrocarbon oils Es = is known to split higher boiling hydrocarbons into lower boiling ones To use silica as a catalyst.

Es wurde nun gefunden, daß man bei der Spaltung von Kohlenwasserstoffölen die Bildung der gasförmigen Kohlenwasserstoffe bedeutend verringern kann, wenn man als Katalysator einen kieselsäurehaltigen Stoff verwendet, der durch Fällen von Wasserglas mit wasserlöslichen Metallsalzen und teilweises Herauslösen des Metalls hergestellt ist. Als Metallsalze kommen in erster Linie Schwermetallsalze oder Salze dreiwertiger Metalle in Betracht.It has now been found that in the cleavage of hydrocarbon oils the formation of gaseous hydrocarbons can be significantly reduced if one a silicic acid-containing substance is used as a catalyst, which is produced by precipitating Water glass with water-soluble metal salts and partial dissolution of the metal is made. Heavy metal salts or salts are primarily used as metal salts trivalent metals into consideration.

Der Katalysator wird in der Weise hergestellt, daß man eine Wasserglaslösung zeit dem Metallsalz, insbesondere seiner wässerigen Lösung, z. B. Lösungen von Salzen von Schwermetallen, wie Eisen, Nickel, Kobalt, Mangan, Chrom, Molybdän, Wolfram, Vanadin, Blei, Zink oder von Aluminium, ferner Magnesium, versetzt. Der Niederschlag wird abgetrennt und zweckmäßig gewaschen. Er kann dann getrocknet und auch höhere Temperaturen, z. B' bis etwa 4oo°, ausgesetzt werden.The catalyst is prepared in such a way that a water glass solution is used time the metal salt, especially its aqueous solution, e.g. B. Solutions of salts of heavy metals such as iron, nickel, cobalt, manganese, chromium, molybdenum, tungsten, Vanadium, lead, zinc or aluminum, also magnesium, added. The precipitation is separated and washed appropriately. He can then be dried and also higher Temperatures, e.g. B 'to about 400 °.

Die teilweise Herauslösung des Metalls aus dem feuchten oder getrockneten Niederschlag geschieht mit Hilfe einer geeigneten Säure, z. B. Salzsäure, Schwefelsäure oder Salpetersäure. Das ,erhaltene, vorzugsweise aus Kieselsäure bestehende Prödukt wird dann, zweckmäßig durch Waschen, von Säure befreit, getrocknet und dann in geeignete Form gebracht.The partial dissolution of the metal from the moist or dried Precipitation is done with the help of a suitable acid, e.g. B. hydrochloric acid, sulfuric acid or nitric acid. The product obtained, preferably consisting of silica is then freed from acid, expediently by washing, dried and then converted into suitable Brought shape.

Dieser Katalysator wird zum Spalten von Kohlemvasserstoffölen, wie Erdölen, Teeren, Druckhydrierungsprodukten von Kohlen, Teeren, Mineralölen oder synthetisch aus Kohlenoxyd und Wasserstoff .erhaltenen ölen, verwendet. Beispiel i,5 kg z8 o!oige Wasserglaslösung werden mit Wasser ,auf iol verdünnt und dann unter Rühren mit einer Lösung von 65og Ferrichlorid (FeCh # 6H20) in 21 Wasser versetzt. Der erhaltene Niederschlag wird durch Filtrieren abgetrennt, gewaschen, durch Erhitzen bis etwa q.oo° getrocknet und dann mit io%ig,er Salzsäure so lange gewaschen, bis keine Gelbfärbung der Säure mehr eintritt. Der kieselsäurehaltige Rückstand wird dann mit Wasser säurefrei nachgewaschen, durch Erhitzen bis etwa ioo° getrocknet, geformt und dann einer Temperatur von 4oo° ausgesetzt.This catalyst is used to crack carbon hydrogen oils, such as Petroleum, tars, pressure hydrogenation products of coals, tars, mineral oils or oils obtained synthetically from carbon monoxide and hydrogen. example 1.5 kg of z8 oily waterglass solution are diluted with water, diluted to iol and then under Stirring mixed with a solution of 65 μg ferric chloride (FeCh # 6H20) in 21 water. Of the obtained precipitate is separated by filtration, washed, by heating Dried to about q.oo ° and then washed with 10% hydrochloric acid until the acid no longer turns yellow. The silica-containing residue is then washed acid-free with water, dried by heating to about 100 °, shaped and then exposed to a temperature of 4oo °.

Wird dieser Katalysator beim Spalten z. B. einer synthetisch aus Wasserstoff und Kohlenoxyd hergestellten Mittelölfraktion verwendet, so ist die Bildung von C3- und Ci-Kohlenwass:erstoffen um etwa 3o bis 40010 geringer als mit bekannten siliciumhaltigen Spaltkatalysatoren, z. B. Aluminiumhydrosilicaten.If this catalyst is used when splitting z. B. one synthetically from hydrogen and carbon monoxide produced middle oil fraction is used, so is the formation of C3 and Ci hydrocarbons: about 3o to 40,010 less than known ones silicon-containing cracking catalysts, e.g. B. aluminum hydrosilicates.

Man erhält ein Produkt mit etwa 35010 Benzin.A product is obtained with about 35010 gasoline.

Verwendet man an Stelle des oben beschriebenen Katalysators einen solchen, der nicht mit ro%iger Salzsäure gewaschen wurde, aus dem also nichts von dem Metall herausgelöst wurde, so erhält man unter Einhaltung der gleichen Spaltbedingungen bei Verwendung des gleichen Ausgangsstoffs !ein-Produkt, das nur etwa 2 50'o Benzin enthält. Verwendet man in an sich bekannter Weise einen Katalysator, der durch Tränken von mit Salzsäure schwach angesäuerter Kieselsäure mit Aluminiumnitratlösung, Trocknen und Erbitzen auf etwa 450' erhalten wurde, so er-4ält man unter Einhaltung der gleichen Spalt-.ledingungen bei Verwendung desselben Ausgangsstoffs ein Produkt mit nur etwa 2 i 0;'o Benzin.If you use a instead of the catalyst described above that which has not been washed with ro% hydrochloric acid, from which therefore nothing of was dissolved out of the metal, this is obtained by observing the same cleavage conditions when using the same raw material! a product that only contains about 2 50'o gasoline contains. If a catalyst is used in a manner known per se, by impregnation of silica weakly acidified with hydrochloric acid with aluminum nitrate solution, drying and eruption to about 450 'has been obtained, it is obtained by observing the same Gap conditions when using the same starting material a product with only about 2 i 0; 'o gasoline.
