Composite ceramic hollow fibres method for production and use thereof

摘要

The invention relates to composites, comprising at least one hollow fibre, made from an oxygen-transporting ceramic material which is a combination of oxygen anion and electron-conducting ceramic material, or a combination of oxygen anion conducting ceramic material and electron-conducting ceramic or non-ceramic material, whereby the outer surface of the hollow fibre is in contact with the outer surface of the same or a different hollow fibre and the contact points are connected by means of sintering. Further composites contain at least one hollow fibre, made from oxygen transporting ceramic material, which is an oxygen anion and electron-conducting ceramic material, or a combination of oxygen anion conducting ceramic material and electron-conducting ceramic or non-ceramic material, with a connector element for the introduction or removal of fluids on at least one front face, whereby the hollow fibres and the connector element are connected. The composites are of application in obtaining oxygen from oxygen-containing gas mixtures or for carrying out oxidation reactions.
