Selective Carbon Dioxide Adsorption from N2- Ch4-co2 Mixture on Carbon Molecular Sieves

Cărbunii sită moleculară sunt adsorbanţi carbonici de o mare importanţă. Lucrarea prezintă rezultatele studiului privind prepararea cărbunilor sită moleculară şi modificarea tratamentului cu hidrocarburi care crachează. De asemenea se prezintă procesul de adsorbţie selectivă a dioxidului de carbon din amestecul N2-CH4-CO2 care se realizează într-un echipament special creat în acest scop, bazat ...

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...

Carbon 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...

Prediction of the adsorption capability onto activated carbon of liquid aliphatic alcohols using molecular fragments method

Quantitative structure-property relationship (QSPR) for estimating the adsorption of aliphatic alcohols onto activated carbon were developed using substructural molecular fragments (SMF) method. The adsorption capacity of activated carbon (gr/100grC) for 150 aliphatic alcohols onto activated carbon (AC) is studied under equilibrium conditions. Forward and backwards stepwise regression variable ...
