在 Li-Mn-Ti-O 复合氧化物催化剂上，甲烷氧化偶联反应动力学研究

Kinetic Studies on Partial Oxidation of Methane Over the Li-Mn-Ti-O Catalyst

对复合氧化物 Li-Mn-Ti-O 催化剂上的甲烷氧化偶联反应进行了动力学研究,提出了一个可能机理.实验测得的动力学行为和 C_2选择率随反应条件的改变可由该机理得到合理的解释.

A kinetic study on the oxidative coupling of methane over the Li-Mn-Ti-O catalyst has been carried out,and a supposed reaction mechanism is suggested.The kinetic behav- ior and the change of the selective rate of C_2 with the condition of reaction could be well explained in terms of the mechanism.
