US Classification:

252452

Abstract:

Supported coprecipitated nickel-cobalt-silica and nickel-cobalt-copper-silica hydrogenation catalysts are disclosed. The catalysts are prepared by preparing an aqueous reaction mixture containing nickel and cobalt cations (and optionally copper cations), silicate anions and solid porous carrier particles under agitation to form a coprecipitate of the nickel, cobalt (and optionally copper) and silicate ions onto said solid porous support particles; heating the aqueous reaction mixture; and adding an alkaline precipitating agent to further precipitate the nickel, cobalt (and optionally copper) and silicate anions onto said solid porous carrier particles.

US Classification:

252452

Abstract:

A copper promoted massive nickel catalyst is disclosed which is capable of having a reduced nickel surface area ranging from about 55 to about 100 m. sup. 2 /g as determined by hydrogen chemisorption, after reduction at 400. degree. C. , and a B. E. T. total surface area ranging from about 150 to about 300 m. sup. 2 /g, wherein the amount of copper in the catalyst ranges from about 2 wt. % to about 10 wt. and the amount of nickel ranges from about 25 wt. % to about 50 wt. %, said wt. % of copper and nickle metal are based on the total weight of the catalyst. The copper promoted massive catalysts are prepared by the steps comprising comingling a solution containing copper and nickel cations with another solution containing silicate anions and coprecipitating the copper, nickel and silicate ions in an aqueous solution onto solid carrier particles. The catalysts are useful in hydrogenation processes.

US Classification:

252454

Abstract:

This invention pertains to a method of stabilizing, with respect to atmospheric air, a bed containing pyrophoric reduced metal catalyst with high active metal surface area formed by reduction of a compound of said metal at an elevated temperature ranging from 200. degree. to 500. degree. C. which comprises: (a) continuously circulating through said bed a stream of inert gas while maintaining a catalyst temperature of at least 300. degree. F. (149. degree. C. ); (b) cooling the catalyst throughout the bed with said inert gas until the catalyst in said bed attains a temperature ranging from 50. degree. F. (10. degree. C. ) to 100. degree. F. (38. degree. C. ); (c) decreasing the inert gas flow and progressively adding CO. sub. 2 until the CO. sub. 2 concentration in the gas stream is at least 80%; (d) adding O. sub.
