In the previous kinetics study,we found that there are differencesin the reaction behavior and the pathway of CO_x formation between the LC andSLC Catalysts.In this paper,several mechanisms have been tested.It is con-firmed that the oxidative coupling of methane over the LC follows bangmuir-Hinshelwood mechanism and an adspecies of oxyen in its molecular form(O_2) is the active species.While the reaction over the SLC catalyst follows amodified Rideal-Redox mechanism and an adspecies of oxygen in its atomicform (O~-) is the active species.
