The adsorption and desorption behavior of propene on a commercial Cu-SSZ-13 catalyst was investigated by dynamic adsorption and TPD methods. In order to explore the role of copper species in propene adsorption, the Cu-SSZ-13 catalyst was treated with dilute HNO3 to leach the Cu species present. The untreated and leached catalysts were characterized by XRF, XRD, H-2-TPR, and NH3-TPD techniques, and the impact of adsorption temperature on the adsorption and desorption of propene was evaluated. The adsorption energy of propene was determined by the Langmuir isotherm equation considering temperature dependency. The Cu-SSZ-13 catalyst was determined to have two different adsorption energies (-E-a) of 4.4 and 70.9 kJ/mol in the temperature range of 72-544 degrees C corresponding to, respectively, physisorption and chemisorption of propene. After leaching of the Cu, the adsorption capacity for propene greatly decreased, indicating that Cu species play a significant role in propene adsorption on Cu-SSZ-13. The effect of a range of feed gas components was investigated, H2O being found to significantly hinder propene adsorption at 72 C. (C) 2013 Elsevier B.V. All rights reserved.
