| 摘 要： | Adsorption,diffusion and thermal desorption features of cyclopentane and cyclohexane in silicalite-1 have beeninvestigated using the intelligent gravimetric technique.Both the saturation adsorption loadings and diffusion coef-ficient of cyclopentane were greater than those of cyclohexane.The diffusivity of cyclopentane was about one orderof magnitude greater than that of cyclohexane at the same temperature and initial loading.For cyclopentane,therewas only one kind of desorption process at adsorption loadings lower than 4 muc(molecule per unit cell),but twodesorption processes appeared at the adsorption loadings higher than 4 muc.While for cyclohexane,one desorptionprocess was found in the whole range of loadings.Both thermal desorption peaks of cyclopentane and cyclohexanemoved to higher temperature region with increasing loading.
