It is played completely hydrogenate the catalyst effect on the aromatic ring, a manufacturing method of a supported ultrafine amorphous metallic nickel catalyst

摘要

to really fully hydrogenated a catalyst effect on the aromatic ring, to provide a method for producing a supported type of ultra-fine amorphous metallic nickel catalyst. High pressure reactor lid is opened, in turn, the organic solvent 10 to 1000 (ml), the catalyst support 1-4 g, after adding nickel carbonyl 1 to 100 (ml), close the upper cover. High-purity nitrogen gas was gradually flows into the gas inlet flows out from the gas outlet, until the pressure becomes 2 8MPa, high purity hydrogen gas, gradually introduced into the high pressure reactor via the gas inlet , then, shut the gas inlet valve. By starting the motor drives the magnetic stirrer, after thoroughly stirring and mixing at room temperature, at a fast agitation speed, temperature is rapidly heated until the 70~280 , and keep warm. Nickel carbonyl adsorbed on the surface of the carrier is decomposed to the elemental nickel and the nickel alone is deposited on the surface of the carrier. This, to be really fully hydrogenated a catalyst effect on the aromatic ring, but to produce a supported type of ultra-fine amorphous metallic nickel catalyst.FIELD 1
