考查了吡啶系对催化剂老化的改性作用,提出4-甲基吡啶和3,5-二甲基吡啶可以作为优良的改性剂,增强铜-铬炭催化剂净化氯化氰气体的抗湿稳定性。并指出可能的改性机理是吡啶(系)对催化剂的络合作用。
The effects of pyridine on the aging of catalysts were investigated. It was suggested that 4-methylpyridine and 3,5-dimethylpyridine could be used as excellent modifiers to enhance the anti-wetting stability Sex. And pointed out that the possible modification mechanism is pyridine (system) on the catalyst complexation.
