Kinetics of adsorption of pure and mixtures of linear and branched C6 alkanes onto silicalite by non-equilibrium molecular dynamics
The separation of saturated branched and linear alkanes may be investigated by selective adsorption on microporous organophilic MFI type zeolite. From the literature, adsorption equilibria of mixtures show a favourable selectivity for less branched alkanes [1]. However the separation process is significantly influenced by the transport properties. The knowledge of the transport coefficients of ...
متن کاملSimulating the Adsorption Isotherms of Methane, Ethane, and Propane in the Zeolite Silicalite
Computer simulations are used to simulate the adsorption isotherms of methane, ethane, and propane in the zeolite silicalite. Various zeolite-alkane models have been tested via a comparison with experimental heats of adsorption and Henry coefficients. These tests are used to improve the existing models. It is shown that the calculated adsorption isotherms agree well with the available experimen...
متن کاملAdsorption structure of dimethyl ether on silicalite-1 zeolite determined using single-crystal X-ray diffraction
The adsorption structures of dimethyl ether (DME) on silicalite-1 zeolite (MFI-type) are determined using single-crystal X-ray diffraction. The structure of low-loaded DME-silicalite-1 indicates that all DME molecules are located in the sinusoidal channel, which is the most stable sorption site based on the van der Waals interaction between DME and the framework. The configuration of guest mole...

15 صفحه اولcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
