Studying reaction kinetics can help clarify the effect of temperature on the rate of chemical reactions to meet the needs of reaction process development and reactors . The mass transfer resistance dissolved in the solution can be ignored . However, it is still necessary to evaluate the mass transfer resistance brought about by the diffusion of substances to the outer surface of the catalyst, namely the external diffusion, and the mass transfer resistance accompanying the entry and exit of substances into the pore structure of the catalyst, namely the internal diffusion. According to previous literature reports , when the increase in the apparent velocity of the liquid does not affect the average reaction rate, it can be judged that the external diffusion is eliminated, and the external resistance has been eliminated in the same micro-packed bed reactor has been verified . On the other hand, based on this theory, by calculating the Thiele modulus and efficiency factor, it can be seen that the internal mass transfer resistance is negligible for this kinetic experiment. The hydrogenation of BN can be regarded as a first-order reaction . By optimizing the temperature conditions, it can be seen that the degree of hydrogenation has a good linear relationship with the temperature. The rate equation for the hydrogenation of benzene can be expressed as:
