Ceramic honeycomb filters and catalysts
Current Opinion in Solid State and Materials Science, 1997Abstract Ceramic honeycombs are widely used as catalyst supports and as particulate filters for vehicular emission control. New geometries and materials have been developed for both mobile and stationary applications. Some recent examples are zeolite and carbon honeycomb adsorbers, low expansion heat exchangers, membrane-coated gas filters and finned

Regeneration of Rigid Ceramic Filters
1993The important issues to be addressed in specification and operation of ceramic filters at high temperatures are the long term conditioning behaviour and the filter “cleanability.”. These two aspects of filtration behaviour are inextricably linked and, at the present state of knowledge, very much system-specific, so that experimental work using the dust

Compact Ceramic Membrane Gas Filter
1993A ceramic membrane filter has been developed by CeraMem Corporation which is extremely compact (540 M2/M3) and capable of operation at temperatures exceeding 1270 K. The filter has been tested in a wide range of applications such as removal of flyash from flue gas, diesel exhaust soot filtration, and filtration of hot gases produced in pressurized ...

Granular ceramic filter elements
1997Gas cleaning temperatures have been increasing ever since heat-resistant fabrics boosted the limit for baghouse filtration to 250°C. More recently, commercial hot gas cleaning products, based largely on ceramics, have trebled this temperature limit, allowing even the hottest flue gases to be filtered without cooling. Technical advances promise to raise

Piezoelectric ceramic transformers and filters
Journal of the British Institution of Radio Engineers, 1961The development of improved piezoelectric ceramics has enabled these materials to be used in the design of electronic components. Two new devices are described embodying piezoelectric principles of operation and relying on electromechanical resonance to obtain efficient energy transformation.
