On Reaction Dynamics of Adsorption of N2 in Liquid Fe-C-O System

研究往Fe-C-O系熔体吹氮时吸氮反应动力学,测定了氮分压、氧和碳含量以及温度对吸氮反应速度的影响。通过实验数据处理,得出Fe-C-O系熔体吸氮反应在氧含量较低时是一级反应,较高时是二级反应,氧含量很高时吸氮速度达最低值。碳能显著地降低Fe-C-O系熔体吸氮反应的传质系数。一级反应和二级反应活化能各为131.6 7kJ/mol,122.

Studied the reaction dynamics of the solution of N2 in the liquid Fe-C-O system, measured the effect of partial preasure of N2, content of O2 and C, temperatures on the solution rate. This reaction was in first order when [O] content is lower; it was second order when [O] content is high; the rate of solution is lowest when the [O] content is very high. The influence [C] content on the mass transport constant of solution is evident. The apparent activation energy at first order is 131.6 kJ/mol, and 122.89 kJ/mol at second order.
