초록

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...
