Abstract

A series of fabric filters including P-84, Nomex and PTFE were coated with a commercial $V_2O_5/TiO_2$ catalyst as an effort to develop a functional fabric filter of simultaneous removal of dust and NOx. The coating methods employed are sol-gel coating method, spray coating method and dip coating method, and the effects of coating method on NOx removal performance of functional fabric filter were investigated. Experimental conditions are as follows: the temperatures of $100-250^{\circ}C$ which are the normal operating temperature range of fabric filters, the space velocity of $5,000hr^{-1}$, the oxygen concentration of 6%, and the $NH_3/NO$ ratio of 1.0. Results showed that the sol-gel coating method gave the best NOx removal performance mainly due to its ability in controlling the amount of catalyst and uniform coating.

NOx와 먼지 동시 제거용 기능성 여과포 개발의 일환으로 $V_2O_5/TiO_2$ 계열의 상용촉매를 사용하여 P-84, Nomex, PTFE 여과포에 코팅하였다. 사용된 코팅 방법은 Sol-gel법, Spray 법 그리고 Dip 코팅 방법이었으며 코팅방법이 여과포의 NOx 제거 반응에 미치는 영향을 조사하였다. NOx 제거반응실험은 여과포의 작동온도에 맞는 $100-250^{\circ}C$의 반응온도범위에서, 공간속도 $5,000hr^{-1}$, 산소농도 6%, $NH_3/NO$ 몰비는 1.0의 조건하에서 수행되었다. 본 연구에서 시도된 세 가지 코팅 방법 중 촉매량의 조절 및 균일한 코팅이 용이한 Sol-gel법에 의해 제조된 기능성여과포가 가장 좋은 NOx 전환율을 나타냈다.
