摘要
考察了一元铂与二元铂 铑两种贵金属催化剂对氰化氢的催化燃烧效果 ,探讨了温度、氰化氢浓度、空气含量及气体空速等因素对脱除氰化氢的影响。研究结果表明 :在温度为 72 3K ,混合气中含空气10 %时 ,两种催化剂对较宽空速及较宽浓度的氰化氢均有较好的处理效果。
The catalytic combustion of hydrogen cyanide was studied separately in presence of two kinds of noble metal catalysts,i.e.,unary platinum and dualistic platinum-rhodium.The effects of temperature,hydrogen cyanide concentration,air content and gas space velocity on the removal of hydrogen cyanide were discussed. The results showed that these two catalysts provided fairly good removal effect at a wide range of space velocity and concentration of hydrogen cyanide with 10% air at 723 K.
