Carbon Molecular Sieves for Hydrocarbon Separations by Adsorption

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...

Templated Growth of Carbon Nanotubes on Nickel Loaded Mesoporous MCM-41 and MCM-48 Molecular Sieves

Chemical vapor deposition was employed to synthesize carbon nanotubes with Ni-loaded MCM-41 and MCM-48 as catalysts and acetylene as precursor at 750°C. Mesoporous Ni MCM-41 and Ni MCM-48 molecular sieves were synthesized by a hydrothermal method and were characterized by XRD and N2 adsorption isotherm. The catalytically synthesized carbon materials were characterized with Raman spectroscopy, N...

Preparation 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...

Adsorption Properties of Carbon Molecular Sieves Prepared by a Co-carbonization Process

Carbon molecular sieves (CMSs) are microporous carbon materials whose special textural characteristics enable kinetic separation of gas mixtures, i.e., separation as a result of differences in the diffusion rates of the species involved. For a CMS to be useful for gas separation, it must possess a narrow pore size distribution (PSD) consisting of pore mouths of molecular sizes and a relatively ...
