모형소각로의 촉매에 의한 배기가스 정화특성에 관한 연구

Abstract

In proportion to the increase of industrial development, emission troubles were concerned as global issue. For these reasons, so many researchers and associated institutes effort to reduce pollution with new technology and various devices. As a kind of these methods, we used catalysts as a after-treatment system. At first, we made equipment of model furnace. And various catalysts were equipped at exhaust duct of combustion system, and excess air ratio(α), change cell numbers, catalyst materials(Pt, Pd) were changed as experimental conditions. With these various condition, temperature, NOx, CO, HC, CO2 and O2 concentration were measured. As a result, NOx conversion increased with increasing of cell number in Pd catalyst. And Pt catalyst became 100% conversion at 200 and 300 cell. Also, Pt catalyst was better than Pd catalyst at α=1.5 in this condition. In addition, CO and HC concentrations were decreased at α=1.5 with Pd catalyst.
