Abstract
Low heating value gases are combusted substoichiometrically in two combustion zones in series in contact with two different supported platinum catalysts in which the concentration of platinum in the catalyst in the first zone is higher than the concentration of platinum in the second catalyst. The combusted gas of reduced carbon monoxide can be directly vented to the atmosphere after energy has been extruded from it for a useful purpose.
