摘要：The adsorption of dimethyl disulfide (DMDS) onto ZSM-5 zeolite from methyl tert-butyl ether (MTBE) solution was investigated in the aspects of adsorption equilibrium and kinetics. Factors that influence adsorption process including time, temperature and initial concentration have been investigated carefully. The adsorption kinetics data could be described by pseudo-first-order very well. The Langmuir equation could be used to interpret the adsorption isotherm and the thermodynamic parameters were derived from the Langmuir constant (k(L)). The minus values of enthalpy and Gibbs free energy of adsorption indicate that the adsorption of DMDS on ZSM-5 is exothermic and spontaneous. Adsorption breakthrough curve was found to be typically S-shape. (C) 2016 Elsevier B.V. All rights reserved.
