Structure of toluene6.4-ZSM-5 and the toluene disproportionation reaction on ZSM-5.
The structure of a high-loading complex of ZSM-5 with 6.4 toluene molecules per unit cell has been determined by single-crystal X-ray diffraction. At least three kinds of toluene molecules were identified in the unit cell. Two disordered toluene molecules were located at the intersection of the straight and sinusoidal channels, the third in the sinusoidal channel. One (TOL1) of the two toluene ...
متن کاملA Density Functional Theory Study of the Interactions of H2O with H-ZSM-5, Cu-ZSM-5, and Co-ZSM-5
The interactions of water with H-ZSM-5, Cu-ZSM-5, and Co-ZSM-5 have been investigated by density functional theory (DFT). Calculations were also performed to determine the thermodynamics of metal removal from the zeolite. For all three forms of ZSM-5, water adsorbs by direct interaction of the O atom with the cation and hydrogen bonding of one of the two H atoms with an oxygen atom in the zeoli...
متن کاملEvaluation of absorption efficiency of Zeolite ZSM-5 in the removal of styrene vapors
Background: Volatile organic compounds (VOCs) are one of the most important and prevalent air pollutants. The vapor produced as a result of the vaporization ‎of these compounds, even at very low concentrations, is harmful to the environment and human health. Thus, the aim of this study was to evaluate the removal of styrene vapor from the air flow using Zeolite ‎(ZSM-5) in a continuous ...
متن کاملDeep desulfurization of diesel by adsorption over Ni/ZSM-5
Introduction Environmental restriction regarding the quality of transportation fuels and the emissions from them are the most important issues. Because of more stringent regulations and fuel specifications regarding development of better method for deep-desulfurization of fuels are important. There has been recent interest in developing adsorbents for selective desulfurisation by adsorption. Me...
