Abstract
Abstract ABSTRACT OF THE DISCLOSURE A catalyst comprising carbon fiber coated with at least one catalytic metal, such as the metals of group VIII of the Periodic Table or Zn, Cu, Ag, Au, Cr, Mg or Mn. The catalyst is prepared by submerging the carbon fiber, in the form of a filament, yarn or woven or non-woven textile, in a non-aqueous solution containing an organic compound of the metal or metals to be deposited on the fiber, drying and then pyrolyzing the compounds contained thereon. Optionally, the fiber may then be submerged in an aqueous solution containing an inorganic compound of the metal or metals, dried and pyrolyzed. The resultant cata-lyst composition is useful for a variety of chemical reactions, particularly those carried out in the gaseous state.

A catalyst comprising carbon fibre in a form chosen from the group consisting of a filament, yarn and woven or non-woven textile coated with at least one catalytic metal selected from the group consisting of Pt, Ru, Rh, Os, Ir, Fe, Co, Ni, Zn, Cu, Ag, Au, Cr, Mg, and Mn and alloys thereof.
Claim 2
Dependent Claim
54 words
A catalyst comprising carbon fibre in a form chosen from the group consisting of a filament, yarn and woven or non-woven textile coated with at least one catalytic metal selected from the group consisting of Pt, Ru, Rh, Os, Ir, Fe, Co, Ni, Zn, Cu, Ag, Au, Cr, Mg, and Mn and alloys thereof.
Claim 3
Dependent Claim
165 words
A process for preparing a catalyst comprising carbon fibre in a form chosen from the group consisting of a filament, yarn and woven or non-woven textile as a carrier and at least one catalytically active metal layer, the metal being selected from the group consisting of Pt, Ru, Rh, Os, Ir, Fe, Co, Ni, Zn, Cu, Ag, Au, Cr, Mg, and Mn and alloys thereof, uniformly deposited on the carbon fibre which comprises submerging the fibre in one or more non-aqueous solutions containing one or a plurality of organic compounds of the metal or metals to be deposited on said fibre, drying the thus-treated fibre, heating the dried carbon fibre at a temperature sufficient to pyrolyze the com-pounds contained thereon, further submerging the obtained metal coated carbon fibre in at least one aqueous solution containing one or more inorganic compounds of said metal or metals, drying the thus-treated fibre, and heating the dried carbon fibre at a temperature sufficient to pyrolyze the compounds contained thereon.
Claim 4
