Method and equipment for catalytic analysis of gases

Abstract

Abstract EQUIPMENT FOR CATALYTIC ANALYSIS OF GASES, ESPECIALLY CATALYTIC COMBUSTION ANALYSIS OF INTERNAL COMBUSTION ENGINE EXHAUST GASES, COMPRISING A COMBUSTION CHAMBER FORMED IN A CYLINDRICAL MASS OF METAL AND HAVING AN EXTERNAL HEATING JACKET, THE CHAMBER HAVING INLETS FOR THE GAS TO BE ANALYZED AND FOR OXYGEN FOR COMBUSTION, AND FURTHER HAVING AN OUTLET CONNECTED WITH A PUMP FOR DRAWING THE GASES THROUGH THE CHAMBER. A THERMALLY RESPONSIVE CATALYTIC ELEMENT IS POSITIONED IN THE COMBUSTION CHAMBER AND MEANS ARE PROVIDED FOR INDICATION CHANGES IN ELECTRICAL RESISTANCE OF THE CATALYTIC ELEMENT AND THEREBY INDICATING THE QUANTITY OF THE GAS CONSTITUENT BEING BURNED IN THE CHAMBER. THE EQUIPMENT FURTHER INCLUDES A GAS SCRUBBER EMPLOYING A BASIC MATERIAL HAVING LIMITED SOLUBILITY IN WATER, THROUGH WHICH THE GAS IS PASSED BEFORE ENTERING THE COMBUSTION CHAMBER, TO EFFECT SEPARATION OF MOISTURE, ACID GAS CONSTITUENTS, AND ALSO PARTICULATES, INCLUDING CARBONACEOUS AND LEAD PARTICULATES FROM THE EXHAUST GAS BEFORE ENTRY INTO THE COMBUSTION CHAMBER.
