在第一部分基础上，进一步研究了甲醇完全氧化反应过程中某些物种的行为，证实了甲醇在ＰｄＡｇ／Ａｌ２Ｏ３催化剂上的吸附是该反应的慢步骤，并提出了反应机理，用ＲｕｎｇｅＫｕｔａ法和修正的ＧａｕｓＮｅｗｔｏｎ法求取了各基元步骤的速率常数、活化能和指前因子等动力学参数。
On the basis of the first part, the behavior of some species in the process of complete oxidation of methanol was further studied. It was confirmed that the adsorption of methanol on Pd-Ag / Al2O3 catalyst was the slow step of the reaction and the reaction mechanism was proposed. The Kuta method and the modified Gaus-Newton method were used to obtain the kinetic parameters such as rate constant, activation energy and pre-exponential factor for each elementary step.
