摘要
本文研究了铁、钴、镍三种粉剂在高温下阻止N-N键断键形成N_2的能力。发现它们都能显著地提高氮的回收率,其中铁粉效能最佳,可使N-N键化合物在850℃入口温度下,氮的回收率不低于98％,氮含量在40～100μg/ml范围内,绝对误差不大于2.0μg/ml。
The ability of powdered nickel, cobalt and iron in reducing the tendency to form N_2 has been studied while compound melecules crack at the N-N bond at high temperature. It was found that all three metal powders could evidently increase the recovery of nitrogen, and among them powdered iron was the best for practical purposes. A nitrogen recovery of no less than 98% was allowed at 850℃ inlet temperature. The absolute deviation was less than 2.0μg/ml in the range of 40～100μg/ml for nitrogen.
