Method of reducing NOx and particulates from internal combustion engines

Method of reducing NOx and particulates from internal combustion engines

Oxides of nitrogen are adsorbed onto the surfaces of, and particulates are trapped in, pores of channels (-) in a porous, interdigitated ceramic particulate filter that has relative rotation with respect to a gas inlet distributor. The distributor has a baffle or ribs that causes constantly flowing...

description Oxides of nitrogen are adsorbed onto the surfaces of, and particulates are trapped in, pores of channels (-) in a porous, interdigitated ceramic particulate filter that has relative rotation with respect to a gas inlet distributor. The distributor has a baffle or ribs that causes constantly flowing engine exhaust to enter the filter channels over a large portion of a revolution of the adsorption bed or the distributor, and causes constantly flowing syngas to thereafter pass through those passages during a small portion of each revolution. Either the inlet gas distributor or the filter bed may be rotated to distribute the gases. Dual, alternately regenerated filters may be used.
