  • Filter for treatment of carbon-based particles in exhaust gas and a device for said treatment using said filter
    Patent number: 5800790
    Abstract: A filter is provided for treating carbon-based particles in exhaust gas discharged from a diesel internal combustion engine, etc., said filter providing in addition to a high throughput capacity, excellent durability, and good economic and maintenance properties, and a device for treating carbon-based particles in exhaust gas having a high throughput capacity, the regeneration of which is easy. This filter is obtained by cutting an end face of a coiled material that is obtained by winding a sheet of a high-temperature resistant stainless steel having resistance heat-generating properties to produce fibers, gathering the thus-produced fibers to form a web, sintering the web, heat-treating the sintered web to form an alumina film on the surface of the sintered fibers, and optionally supporting a catalyst on the alumina film.
