Preparation of Carbon Molecular Sieves from Pistachio Shell and Walnut Shell for Kinetic Separation of Carbon Monoxide, Hydrogen, and Methane
In this study, two Carbon Molecular Sieves using Pistachio shell (CMS P) and Walnut shell (CMS W) were prepared by a chemical vapor deposition method and used for pressure swing adsorption and separation of CO/H2 and CO/CH4. Adsorption isotherms of gases obtained for both CMS’s. The Dubinin-Radushkevich isotherm model was used for comparing pore volum...
متن کاملArtificial molecular sieves and filters: a new paradigm for biomolecule separation.
Patterned regular sieves and filters with comparable molecular dimensions hold great promise as an alternative to conventional polymeric gels and fibrous membranes to improve biomolecule separation. Recent developments of microfabricated nanofluidic sieves and filters have demonstrated superior performance for both analytical and preparative separation of various physiologically relevant macrom...
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 کاملPreparation and gas adsorption studies of three mesh-adjustable molecular sieves with a common structure.
Solvothermal reactions of a predesigned amphiphilic ligand, 4'-tert-butyl-biphenyl-3,5-dicarboxylate (BBPDC), with Zn(NO(3))(2), Co(NO(3))(2), and Cu(NO(3))(2) gave rise to three isostructural mesh-adjustable molecular sieves (MAMSs), MAMS-2, MAMS-3, and MAMS-4, respectively. The three new MAMSs all exhibit temperature-tuned molecular sieving effect. There exists a linear relationship between m...
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...
