对JL6A型千瓦级横流连续CO_2激光器工作气体进行了连续检测,考察了Pd-Ni/γ-A1_2O_3和稀土钙钛矿型催化剂对气体净化的效果。当空速为15000小时~(-1),温度为260℃时,稀土钙钛矿型催化剂对CO的转化率为85.1％,对NO_x的转化率为63.1％。
The working gas of JL6A CW CW CO_2 laser was continuously tested and the effects of Pd-Ni / γ-Al 2 O 3 and rare earth perovskite catalysts on gas purification were investigated. When the space velocity is 15000 h -1 and the temperature is 260 ℃, the conversion of CO to 85.1% and the conversion of NO x to rare earth perovskite catalyst are 63.1%.
