摘要:Selective catalytic reduction (SCR) of NOX is among the leading edge of the emerging hotspot of deNOx technologies. However, most of the reported investigations were bench-scale study, which were limited to represent the performance of catalysts at real applications. With the successful construction of pilot scale (10000 Nm3/h) SCR system at a cement kiln, we systematically investigated the effect of NH3/NOx molar ratio, catalyst volume and system stability on NOx removal efficiency. It is found that when the inlet NOx concentration was at the range of 200 to 300 mg/m3, the corresponding outlet NOx concentration was below 50 mg/m3 during 168 operating hours with ammonia emission below 0.98 mg/m3 at NSR of 0.89-1.0.
