A gas filter, a process for producing a gas filter and the use of the gas filter. The filtration of gases, in particular of gases which are contaminated by solids, e.g. automobile exhaust gases, is difficult since the solids which have been filtered out block the filter over the course of time. The gas filter of the invention can be used over relatively long periods of time since it is regenerable. The improvement achieved by the invention compared to conventional gas filters is that the filter comprises a composite material which can be heated in a simp...
1. A regenerable gas filter for filtering gases which comprises a bendable and rollable composite material based on at least one open-structured and material-permeable support and having on at least one side of the support and in the interior of the support at least one inorganic component consisting essentially of at least one compound of a metal, a semimetal or a mixed metal and at least one element of main groups III to VII, wherein the composite material has a thickness of 5 to 150 .mu.m and can be bent to a radius of down to 2 mm and wherein the com...
