摘要
在中性、弱还原性及强还原性气氛和不同温度下处理 B-02铁系丁烯氧化脱氢催化剂,将其比表面、平均晶径、Fe^(2+)含量、炭含量、相对反应速度(以新鲜催化剂为1)分别与处理的烈度因子(?)相互关联,并与其工业运转的老化程度和(?)的关系相比较,发现二者是相似的.由此提出了模拟工业运转催化剂失活的加速老化的方法.
The effects of serverity of treatment in neutral,weak reducing and reducing
media at different temperatures on the surface area,relative activity,coke de-
position,mean crystallite size and Fe^(2+) content of B-02 (?)errite catalyst have been
studied.These severe treatments show some analogy with commercial run of long
duration.Hence the method of accelerative ageing catalyst which can simulate
the deactivation of catalyst during commercial run has been proposed to es-
timate the life performance of catalyst.
