International Classification:

B01J 2108
B01J 3100
B01J 2722
B01J 2724

US Classification:

502258

Abstract:

Disclosed is a method for preparing dual colloid catalyst compositions which are suitable for use in such processes as ammonia synthesis, carbon monoxide hydrogenation, hydrogenation and denitrogenation. The method comprises forming a gel, or suspension, by admixing: (i) one or more transition metal cyano-containing anionic-complex solutions wherein at least one solution contains a reducible transition metal, and wherein one or more of these solutions optionally contains a nonreducible metal, with (ii) one or more solutions containing polyvalent metal cations. The resulting gel, or suspension is heated to a temperature of about 90. degree. C. to about 150. degree. C. for an effective amount of time to allow hydrolysis and polymerization to occur. The resulting solid is then filtered and ion exchanged with ions of one or more metals selected from those exchangeable metals from groups IA, IIA, IIIB, IVB, VIB, VIIB, and VIII of the Periodic Table of the Elements. The resulting ion-exchanged material is then dried.

Abstract:

Disclosed herein are catalyst compositions comprised of: (a) from about 15 to about 85 wt. % of crystallites selected from the group consisting of (i) crystallites of one or more transition metals and (ii) crystallites of reducible transition metal carbides and nitrides, and mixtures thereof, said transition metal being selected from those reducible metals from Groups IB, IIB, VIB, VIIB, and VIII of the Periodic Table of the Elements, wherein at least 80% of the crystallities have a diameter, d, between about 25. ANG. and 500. ANG. with the proviso that the crystallite size distribution of at least about 80% of these be expressed by the relationship 0. 5D

Angelo A. Montagna - Summit NJ

Assignee:

Exxon Research & Engineering Co. - Florham Park NJ

International Classification:

B01J 2500

US Classification:

502301

Abstract:

An improved catalyst for the synthesis of ammonia is described wherein a promoted iron-derived, pre-reduced catalyst is oxidatively leached with a neutral aqueous solution of potassium cyanide. Preferably an organic carboxylic acid such as citric acid is added to the aqueous solution to maintain the pH at about neutral. The resulting leached catalyst has a markedly higher activity than the unleached catalyst. The leached catalyst may be contacted with a cobalt complex or a nickel salt to incorporate cobalt or nickel therein which catalysts are also useful for ammonia synthesis.

Abstract:

Disclosed is a method for preparing dual colloid catalyst compositions wherein a gel, or colloidal suspension is formed by admixing (a) a 0. 6 to 10M aqueous solution containing one or more soluble salts or complexes of one or more transition metals, wherein at least one of the transition metals is reducible and hydrolyzable, and one or more elements selected from Cr, Al, Si, Th, U, the lanthanides, and elements from Groups IA and IIA of the Periodic Table of the Elements, with (b) a 0. 5 to 10N aqueous base solution. The solid material is separated from the resulting gel, or colloidal suspension and washed and dried.
