• 摘要：在Pt/Al₂O₃催化剂用玻璃外循环无梯度反应器研究了丁烷、反-丁烯-2及顺-丁烯-2深度氧化动力学。深度氧化服从L-H机理模型。用正交设计法估计了动力学方程中的参数值。用脉冲色谱法研究深度氧化的L-H机理,并测定了吸附热。求出了深度氧化的CO₂生成速度。

• Abstract：The kinetics of deep oxidation of butane,trans-butene and cis-butene-2on Pt/Al2O3 catalyst has been investigated by a flow-recirculatiqn glass reactor. The kinetics of the reactions was found to obey the L-H model. The parameter values of the kinetic equation were estimated by the method of orthogonal design. A pulse method was used to discriminate the L-H model and to determine the adsorption heats of butane, trans-butene-2,cis-butene-2 and oxygen. The rate of CO₂ formation during the oxidation might be described by the equations (11).

• Key words：butane  trans-butene-2  cis-butene-2  catalyst  deep oxidation  L-H model.
