Title: Thin film alumina catalysts
IPC: B01J37/02
Filed: 1961-09-27
Abstract: Water dispersable alumina hydrate is made by hydrolysing an aluminium containing material, which may be aluminium metal, aluminium salts for example the nitrate or chloride, or aluminium alcoholates, separating the hydrolysed alumina from the mother liquor for example by centrifuging and drying the resulting alumina hydrate at between 5 DEG  to 60 DEG  C. and preferably 15 DEG  to 40 DEG  C., to preferably 70% by weight of the total water content.  The resulting alumina is suitable for forming thin film catalysts (see Division B1).  In the example aluminium nitrate is hydrolysed with ammonia until pH 8 to 8.5 had been achieved, the hydrogel was thereafter thoroughly washed and aged at 70 DEG  C. for 16 hours and dried at 30 DEG  C.ALSO:Catalysts having a film of alumina containing material to 300 microns thickness on a support are made by a process which comprises the steps of forming an alumina hydrate slurry by hydrolysing an aluminium containing material, specifically aluminium metal, aluminium salts for example nitrate or chloride, or aluminium alcoholates, to form an alumina hydrate hydrogel, drying the hydrogel at a temperature from 5-60  DEG C. and preferably from 15-40  DEG C., and preferably to a water content of 70% by weight, re-slurrying the dried material in water, preferably containing an aluminium salt, for example, the nitrate, coating the support therefrom with a film of alumina hydrate, and thereafter calcining the alumina hydrate to alumina.  The support may be active or merely inactive, for example, aluminium or alpha-alumina.  Other catalytically active materials which may be added at any suitable point in the catalyst preparation except when it is a cobalt or molybdenum compound may be added to the alumina.  Specified additives include silica, magnesia, hydrogenation active catalytic metals of Group VIa and VIII of the Periodic Table, for example, oxides or sulphides of iron, cobalt or nickel, or platinum metal, and known catalysts such as cobalt molybdate.  In the examples the alumina hydrogel is prepared by the hydrolysis of aluminium nitrate with ammonia, followed by drying at 30  DEG C. This material is slurried with water and aluminium foil is coated with the slurry as made as well as with an aluminium nitrate containing slurry.  The specimens were dried at 90  DEG C. and calcined at 550  DEG C. to yield film thicknesses of 6 microns.  A further example describes the preparation of aluminium foil supported catalysts which incorporate ammonium molybdate and cobalt nitrate in the catalytic layer and their effectiveness in de-sulphurization is demonstrated.

Optionally, the inactive alumina may be treated with said solution either before treating with a solution containing an active oxygen compound or together with a solution containing an active oxygen compound. The alkaline solution may be of alkali metal or alkaline earth metal hydroxides, e.g. 0À1-3% NaOH. The temperature may be 20-100 C. and treatment time may be 1-10 days. The active oxygen containing compound may be sodium perborate, sodium percarbonate, percarbamide or hydrogen peroxide. Prior to regeneration the alumina may be washed with an organic solvent and treated with water vapour and following regeneration may be washed with water or may be washed with water and then steamed or may be washed with water and an organic solvent and then steamed and in each case dried. In examples, an Al 2 O 3 - containing tower is introduced into the working solution circuit to remove tetrahydro anthraquinone epoxide. When the alumina becomes inactive it is treated with NaOH solution, and by washing with water and acetone.
