Air Emissions Control: Catalytic Reduction/Oxidation

This is a more-detailed introduction to one such class of technologies, catalytic reduction/oxidation. It will cover selective and nonselective catalytic reduction (SCR and NSCR) for the control of nitrogen oxides (NOx), as well as catalytic oxidation for the control of carbon monoxide (CO) and volatile organic compounds (VOCs.) The article explains what catalytic reduction/oxidation is and how it works, outlines its advantages and limitations, and educates the reader so he/she can determine whether it is appropriate for a particular application and if so, what the next step(s) is(are).
