前文曾报导了在合成氨反应条件下氮、氢吸附与纯氮、纯氢吸附的差别。这种差别是由于在反应条件下氢、氮相互作用的结果。在前文提出的反应机理中,我们用表面反应和诱生吸附两种相互作用来说明在反应条件下的吸附和动力学规律。显然,表面反应只能出现于反应条件下,它是反应条件下的特性,而诱生吸附的相互作用在不起反应的情况下,例如在混合吸附过程中,也可能存在。根据这种理解,混合吸附可能比纯吸附更接近于反应条件下的吸附。因此,我们在较低温度(0℃)下进行了氢、氮混合吸附实验,以了解混合吸附过程与反应条件下的吸附作用的联系。实验结果表明,0℃
The previous article reported the differences between nitrogen and hydrogen adsorption and pure nitrogen and pure hydrogen adsorption under the conditions of synthetic ammonia reaction. This difference is due to the reaction of hydrogen and nitrogen under the reaction conditions. In the reaction mechanism proposed in the previous section, we describe the adsorption and kinetic rules under the reaction conditions by using the two reactions of surface reaction and induced adsorption. Obviously, the surface reaction can only occur under the reaction conditions, it is under the conditions of the reaction characteristics, and the interaction induced by adsorption can not react, such as in the mixed adsorption process may also exist. According to this understanding, hybrid adsorption may be closer to adsorption under reaction conditions than pure adsorption. Therefore, we carried out hydrogen and nitrogen mixed adsorption experiment at lower temperature (0 ℃) to understand the relationship between the mixed adsorption process and the adsorption under the reaction conditions. The experimental results show that 0 ℃
