Thermal and Catalytic Conversion of Gas Impurities

The thermal and catalytic conversion processes described in this chapter involve the chemical reaction of one or more gas phase species, including the impurities to be removed, to form new species, which remain in the gas. In thermal processes the desired reaction occurs at an acceptably high rate as a result of operating the reactor at an elevated temperature. Ill catalytic processes the reaction rate is accelerated at a low or moderate temperature by the presence of an active catalyst.
