Molecular simulations of the adsorption and diffusion of hydrocarbons in molecular sieves
In this short review it is demonstrated how molecular simulation can be used to obtain molecular insights in the behaviour of molecules inside the pores of zeolites. Whereas straightforward molecular dynamics can be used to study the behaviour of small molecules inside the pores, the study of the long chain hydrocarbons that are important in petrochemical applications require special computatio...
متن کاملSorption of aromatic hydrocarbons onto montmorillonite as affected by norfloxacin.
Effect of norfloxacin (Nor) on the sorption of 1,3-dinitrobenzene (1,3-DNB), and PAHs (naphthalene (NAPH), phenanthrene (PHEN) and pyrene (PYR)) to K(+)-montmorillonite was studied. Nor suppressed 1,3-DNB sorption due to their competition for the same sorption sites. 1,3-DNB was sorbed on K(+)-montmorillonite surface via cation-polar interaction and n-π electron donor-acceptor interaction. Nor ...
متن کاملEnantiomerically enriched, polycrystalline molecular sieves.
Zeolite and zeolite-like molecular sieves are being used in a large number of applications such as adsorption and catalysis. Achievement of the long-standing goal of creating a chiral, polycrystalline molecular sieve with bulk enantioenrichment would enable these materials to perform enantioselective functions. Here, we report the synthesis of enantiomerically enriched samples of a molecular si...
متن کاملIonothermal synthesis of aluminophosphate molecular sieves
Effects of ionic liquid structures on the aluminophosphate molecular sieve products in ionothermal synthesis process were investigated. The results showed that the possible structure-directing effect of ionic liquid might exist during ionothermal synthesis. Microwave heating was introduced into the ionothermal synthesis, which led to a fast and safe process for preparation of molecular sieves. ...
متن کاملCarbon Molecular Sieves – A kinetic study
Carbon Molecular Sieves (CMS) are unique materials which are widely used in processes based on pressure swing adsorption (PSA) for nitrogen generation by oxygen removal from air [1, 2, 3] and for the enrichment of methane from biogas or landfill gas [4]. Steadily improved CMS were launched in the last years to cover these applications. The recent materials are characterized by higher sorption c...
