【Abstract】 The catalytic behavior of ZnO/HZSM-5 catalysts in aromatization of cyclopentane has been studied by con-tinuous-flow method. As a result of addition of ZnO to HZSM-5, the anticoking behavior of the catalysts is en-hanced. The catalytic activity of the catalysts has been determined by the pulse microreaction technique,and the apparent reaction rate constant of cyclopentane on ZnO (1 % ) /HZSM-5 at various temperatures has been ob-tained. From the adsorption heat btoained by chromatography and the apparent activation energy,the activation energy of surface reaction has been calculated,the value is 131. 2KJ/mol.更多还原
