| Abstract: | The ZSM-5 zeolite was synthesized with inorganic amine plate.The data of Pulse catalytic isomirization of m-xylene on the HZSM-5 were measured in various temperatures and carrying gas flow rates.Experimental results showed that the main conversion process of m-xylene on the HZSM-5 zeolite was unimolecular transfer reaction appearing as a first order kinetic characterization in the reaction conditions of temperture range of 758~801 K,carrying gas flow rate and pressure in the region of 22~60 ml/min and 0.2~0.3 Mpa respectively.The apparent activation energy,the adsorption heat and the activation energy of surface reaction were 119.2 kJ/mol,47.2 kJ/mol and166.4 kJ/mol respectively. |
