제목 Characterization and catalytic investigation of particle size of washcoat material for NH3-SCR
초록 The standards of regulation of the atmospheric pollutants become more and more severe. If the gas mixture contains a large excess of oxygen (e.g. lean-burn gasoline and diesel engines), the NOxreduction in N2 becomes difficult.
NH3-SCR, the selective catalytic reduction using NH3 as reducing agent, has been investigated for about 10 years in detail and today is a well established technique for DeNOx of stationary diesel engines. It is presently also considered as the most promising way to diminish NOx emissions originating from heavy duty vehicles, especially trucks.
The paper discusses DeNox performance of various ZSM5 and the promotion effect of particle size of washcoat material with bench test. Particle size of washcoat material was measured with laser diffraction particle size analyzer.
