Operating Characteristics of an NSCR Catalyst on an 80 kW Cummins-Onan Genset
Non-Selective Catalytic Reduction (NSCR) can be an effective means for emissions control for engines that operate at stoichiometric air-fuel ratios(rich burn engines). NSCR catalysts simultaneously reduce NOx, THC, CO, and formaldehyde (CH20) when the equivalence ratio is controlled within a narrow operating range. When the equivalence ratio falls outside the operating range, emissions reduction efficiency for one or more constituent will be poor, and excessive ammonia (NH3) formation in the catalyst can occur. In this paper, the operating characteristics of a commercially equivalence ratio (0.99-1.05), space velocity (20,000/hr-430,000/hr), and catalyst temperature (350oC-600oC). Catalyst performance for all constituents (NOx, THC, CO, and CH20) is examined at the NOx-CO efficiency cross-over point. The maximum NOx reduction efficiency and maximum NH3 emissions are determined at rich equivalence ratios. The effect of space velocity and temperature on the above performance parameters is discussed. The required equivalence ratio control band to meet current and pending regulations is assessed.
