Open-porous structure through which a fluid can flow, formed from ceramic fiber and catalytically active element, which is cohesively bonded with ceramic material of fiber on surface, useful for reforming hydrocarbon compound and ethanol

摘要

Open-porous structure through which a fluid can flow, formed from at least one ceramic fiber, and at least one catalytically active chemical element, which is cohesively bonded with a ceramic material of the fiber on the surface, is claimed. An independent claim is also included for producing the open-porous structure through which a fluid can flow, comprising; extruding a powdered ceramic material in a suspension with a polymer and a solvent into at least one fiber; forming a green solid structure, and subsequently expelling the organic components in a heat treatment; sintering the structure; then coating with a solution containing at least one chemical compound of a catalytically active element on the surface of the sintered structure; and carrying out a chemical reduction of the chemical compound in an additional heat treatment in a reducing atmosphere that results cohesively bonding of at least one catalytically active element containing the chemical compound on the surface of the structure.
