Abstract
A modular filter for removing particulate matter from gases or liquids is disclosed. The filter includes at least two porous ceramic or ceramic composite modules and a heater structure for regenerating the modules by heating which is integral with the modules. The regenerating structure may also be a ceramic structure. The filter modules may be manufactured using micropyretic synthesis and manufactured to have interconnected porosity. The filter may be used to remove particulates from the exhaust of engines such as engines of land and water vehicles.
