用玻璃流动外循环反应器研究了Fe_(4.9)Zn_(0.9)Mg_(0.1)(原子比)催化剂上丁烯-1氧化脱氢动力学,丁烯-1氧化脱氢制丁二烯、丁烯-1及丁二烯深度氧化生成CO_(2)的动力学用双反应分子强吸附的L-H(Lang muir Hinshelwood)机理方程描述。速度方程的参数用非线性最小二乘法估计,得丁二烯生成速度rD和CO_(2)生成速度rco2的动力学方程式。

The kinetics of oxidative clehydrogenation of butene-1 to butadiene over Fe_(4.9)Zn_(0.9)Mg_(0.9)(atomic ratio)catalyst has been investigated in a flow-reeirculation glass reactor.The Kinetics of oxidative dehydrogcnation of butene-1 to butadiene and deep oxidation of butene-1 and butadiene to CO_(2)is described by the equations of Longmuir Hinshelwood mechanism of strong adsorption of bimolecular reaction.The kinetic parameters of rate equations were estimated by non-linear least square.The rate equation for formation of butadiene is.
