Abstract
1420968 Treating exhaust gases ENGELHARD MINERALS & CHEMICALS CORP 15 Dec 1972 [17 Dec 1971] 58201/72 Heading B1W [Also in Divisions F1 and F4] A method of oxidising a carbonaceous fuel which when burned with a stoichiometric amount of air has an adiabatic flame temperature of at least 3300‹F, comprises partially combusting the fuel with air in a thermal combustion zone, cooling the products, and then effecting further adiabatic oxidation of at least 10% of the fuel supplied to the thermal combustion zone by contacting the cooled products with an oxidation catalyst at a temperature of between 1500 and 3000‹F. In one arrangement a compressor 12 delivers part of its air output through line 28 and valve 30 to a combustion chamber 16 where between 35% and 75% of the hydrocarbon fuel supplied through line 18 is burnt. The products are cooled in zone 40 by a further portion of the air output of compressor 12 supplied through line 38 and enter chamber 42 where the fuel is further oxidised adiabatically in contact with catalyst 46. Additional fuel may be added between chambers 16, 42. The purified products expand through turbine 14 driving compressor 12 and providing useful power. An additional combustion chamber may be disposed between catalyst chamber 42 and turbine 14. In a modification (Fig. 2 not shown) catalyst chamber 42 is provided between turbine 14 and a downstream separate power turbine (56) and thus acts as an interstage reheater. Oxidation of the gases leaving the catalyst chamber may continue during expansion through the turbine. The fuels and catalysts are specified and are generally as described in Specification 1395422. In further modifications the quenching of the partially combusted fuel may be effected by indirect heat exchange, or by direct heat exchange by contact with a ceramic heat rink or the catalyst in the oxidation zone. The gases leaving the catalyst chamber may be used as the heat source for a water-tube boiler, rather than driving a turbine.
