Disclosed is a composition of an essentially solid phase state having as components, a liquid hydrophilic organic polymer, an aqueous salt solution containing at least one metallic or metalloid element, and a coagulating agent. The composition on calcination provides a metal-containing powder having an average particle size of 1 micrometer or less. Such metal-containing powders are of value in the preparation of industrial catalysts, ceramics, electronic components, or as fillers in plastics, paints or cosmetics.

Composition comprising a metal salt and metal powder therefrom by the

A catalyst comprising a preshaped porous support material having applied thereto in finely divided form an active compound chosen from at least one compound of vanadium, chromium, manganese, iron, cobalt, nickel, copper and zinc, and optionally a promoter chosen from at least an alkali or alkaline earth metal compound, method for the preparation thereof and use thereof in the dehydrogenation of hydrocarbons.

Catalystic method for the dehydrogenation of hydrocarbons

Process for removing mercury from an organic medium which at least contains mercury and arsenic, wherein the organic medium is contacted with a solid polymeric substrate containing thiol groups bound to the polymeric substrate through aliphatic groups.
