Execution of catalytic processes. Patented in the German Empire on March 27, 1914 .

It has been found that catalytic processes can be carried out in a very advantageous manner let, if the contact masses required for it by the action of connections the contact metals in question for insoluble, base-exchanging compounds and, if necessary suitable aftertreatment (heating, reduction or the like.) These contact materials are not only very simple produce, but they are also characterized by an excellent effectiveness. In this way, a wide variety of contact processes, such as hydrogenation, Reductions or oxidations, etc. using any, for the concerned Carry out procedures for suitable contact materials.

The use of the process for purposes of water purification as well as catalytic Generation of oxygen from hypochlorite solutions is excluded.

Example 1.

100 parts of artificial sodium zeolite (such as * 25 for those present. B. branded · "Pcrmutit" in the trade) are in grains in the cold or heat with a weak hydrochloric acid solution of 0.1 to 0.5 parts PAI ladiumchlorür digested until the solution has become discolored. This is washed out, dried and, if necessary, z. B. reduced at a slightly elevated temperature with hydrogen. The contact mass obtained in this way can be used in the usual manner without further ado or after pulverization has taken place, for. B.

use for hydrogenation or dehydrogenation of organic compounds, in the former case, the Ricsel process is advantageously used for liquids can. Instead of artificial sodium zeolite you can also use natural zeolites use.

Example 2.

Artificial sodium zeolite is mixed with an io percent nickel nitrate solution a few times each time treated with subsequent washing out in the heat, whereby an exchange of sodium for nickel takes place, and the thus obtained, z. B. about 10 percent nickel containing, granular mass and dried with Reduced hydrogen at 300 to 400 ° or above. Leave by means of this contact mass z. B. hydrogenate any oils in an excellent manner. "

Example 3.

Artificial sodium or ammonium zeolite is converted into manganese zeolite by treatment with manganese sulphate solution; this can z. B. as a catalyst in the oxidation of ammoniacal ammonium sulfite solution to use ammonium sulfate by means of air.

Correspondingly, for the purpose of producing contact masses with other catalyzing Process metals or metal compounds in which v n & fn z. B. Artificial Zeolite with solutions of other metal salts ζ. Β. of copper, zinc, vanadium, etc., possibly also
