Apparatus and process for removing particulates from a flow of exhaust gas exhausted from a diesel engine and trapped in a filter including a compressor which produces dry compressed air and transports it into at least one oxygen saturation container provided with an oxygen adsorber adapted to receive the compressed air and adsorb oxygen from it. The oxygen enriched air thus generated is directed through a valve and conduit into a section of the particulate filter wherein the high partial pressure of oxygen causes particulate combustion. Each section of the trap is exposed in turn to the oxygen enriched air thus effecting a complete regeneration of the filter. Oxygen depleted compressed air is directed through the valve and separate conduit to a reservior where it can be used for actuating the air brakes of a vehicle or other compressed air uses.

A process for low temperature combustion of diesel particulates trapped in a vehicle emission filter using compressed air produced by compressor means in the vehicle air brake system comprising the steps of: a. adsorbing oxygen from compressed air used to actuate a vehicle air brake system by allowing the compressed air to flow into an adsorber means within a container; b. venting the compressed oxygen depleted air from the container into the vehicle air brake system; c. desorbing the sorbed oxygen enriched air so that it has an enriched oxygen content ranging from 30 to 60% O2; d. feeding the pressurized enriched oxygen into exhaust gases entering a diesel filter comprising a plurality of cells so that the combined gases in the cells have an enriched oxygen content which is greater than 20.8% O2; and e. burning the oxygen enriched exhaust gases to a temperature range from 250°to 400°C. for combustion of filter particulates. Apparatus for removing particulates from a flow of exhaust gas exhausted from a diesel engine and trapped in a filter comprising: means for producing compressed air, oxygen saturation means connected to the means for producing compressed air comprising at least one container provided with oxygen adsorber means receiving said compressed air and adsorbing oxygen therefrom; means to desorb oxygen from said oxygen adsorber means to form oxygen enriched air having more than 20.8% O2, conduit means providing communication of said oxygen saturation means with a filter, said filter comprising a porous ceramic monolithic structure defining a plurality of cells which extend through the structure, and valve means positioned in said conduit means to selectively direct oxygen enriched air of at least 20.8% O2 into the cells of said filter which with the exhaust gases passing into said filter provide for combination of particulates trapped in said filter.
