Abatement of smog in flue gases

Claim 1

THE METHOD OF TREATING HOT, SUBSTANTIALLY OXYGEN FREE FLUE GAS DRIVED FROM THE COMBUSTION OF CARBONACEOUS AND HYDROCARBONACEOUS MATERIALS, AND CONTAINING SMOG-FORMING CONTAMINANTS INCLUDING RESIDUAL NON-COMBUSTED HYDROCARBONACEOUS MATERIAL HAVING A RELATIVELY HIGH DEW POINT AND FINELY-DIVIDED SOLID CARBONACEOUS MATERIAL WHICH COMPRISES THE STEPS OF: PRE-COOLING SAID FLUE GAS TO A TEMPERATURE BELOW HE DEW POINT OF SAID RESIDUAL HYDROCARBONACEOUS MATERIAL TO THEREBY CONDENSE SAID HYDROCARBONACEOUS MATERIAL INTO A FINE DISPERSION OF LIQUID PARTILES; INTRODUCING THE COOLED FLUE GAS INTO ONE END OF A CONFINED CYLINDRICAL COMBUSTION ZONE HAVING A PERIPHERAL PERMEABLE ENVELOPE OF COMBUSTION CATALYZING MATERIAL, WHILE IMPARTING TO SAID FLUE GAS A WHIRLING MOTION ADAPTED TO CENTRIFUGALLY CONCENTRATE SAID CARBONACEOUS MATERIAL AND SAID CONDENSED HYDROCARBONACEOUS MATERIAL AT THE SURFACE OF THE CATALYST ENVELOPE; INTRODUCING OXYGEN-CONTAING GAS INTO A CONFINED ANNULAR ZONE SURROUNDING SAID CATALYST ENVELOPE; PASSING SAID OXYGEN-CONTAINING GAS THROUGH THE ENTIRE ENVELOPE OF PERMEABLE CATALYST INTO SAID COMBUSTION ZONE, THEREBY EFFECTING A COMBUSTION OF THE CENTRIFUGALLY-SEPARATED HEAVIER PARTICLES OF CARBONACEOUS AND HYDROCARBONACEOUS MATERIALS IN THE PERIPHERAL REGION OF SAID COMBUSTION ZONE; AND VENTING THE TREATED FLUE GAS STREAM FROM THE OTHER END OF SAID COMBUSTION ZONE.

Claim 2

THE METHOD OF TREATING HOT, SUBSTANTIALLY OXYGEN FREE FLUE GAS DRIVED FROM THE COMBUSTION OF CARBONACEOUS AND HYDROCARBONACEOUS MATERIALS, AND CONTAINING SMOG-FORMING CONTAMINANTS INCLUDING RESIDUAL NON-COMBUSTED HYDROCARBONACEOUS MATERIAL HAVING A RELATIVELY HIGH DEW POINT AND FINELY-DIVIDED SOLID CARBONACEOUS MATERIAL WHICH COMPRISES THE STEPS OF: PRE-COOLING SAID FLUE GAS TO A TEMPERATURE BELOW HE DEW POINT OF SAID RESIDUAL HYDROCARBONACEOUS MATERIAL TO THEREBY CONDENSE SAID HYDROCARBONACEOUS MATERIAL INTO A FINE DISPERSION OF LIQUID PARTILES; INTRODUCING THE COOLED FLUE GAS INTO ONE END OF A CONFINED CYLINDRICAL COMBUSTION ZONE HAVING A PERIPHERAL PERMEABLE ENVELOPE OF COMBUSTION CATALYZING MATERIAL, WHILE IMPARTING TO SAID FLUE GAS A WHIRLING MOTION ADAPTED TO CENTRIFUGALLY CONCENTRATE SAID CARBONACEOUS MATERIAL AND SAID CONDENSED HYDROCARBONACEOUS MATERIAL AT THE SURFACE OF THE CATALYST ENVELOPE; INTRODUCING OXYGEN-CONTAING GAS INTO A CONFINED ANNULAR ZONE SURROUNDING SAID CATALYST ENVELOPE; PASSING SAID OXYGEN-CONTAINING GAS THROUGH THE ENTIRE ENVELOPE OF PERMEABLE CATALYST INTO SAID COMBUSTION ZONE, THEREBY EFFECTING A COMBUSTION OF THE CENTRIFUGALLY-SEPARATED HEAVIER PARTICLES OF CARBONACEOUS AND HYDROCARBONACEOUS MATERIALS IN THE PERIPHERAL REGION OF SAID COMBUSTION ZONE; AND VENTING THE TREATED FLUE GAS STREAM FROM THE OTHER END OF SAID COMBUSTION ZONE.
