Synthesis and Characterization of a Novel Multifunctional Carbon Molecular Sieve
Carbon molecular sieves were prepared from petroleum coke by chemical activation. The effects of activation temperature, holding time, preliminary treatments and activated agent ratio on surface area, pore structure of the carbon molecular sieves produced in our lab were investigated. The specific surface area and average pore size of the carbon are obviously increased with increasing use of ac...
متن کاملCarbon Dioxide Sorption in a Nanoporous Octahedral Molecular Sieve
We have performed first-principles density functional theory calculations, incorporated with van der Waals interactions, to study CO2 adsorption and diffusion in nanoporous solid – OMS2 (Octahedral Molecular Sieve). We found the charge, type, and mobility of a cation, accommodated in a porous OMS-2 material for structural stability, can affect not only the OMS-2 structural features but also CO2...
متن کاملMixed Matrix Carbon Molecular Sieve and Alumina (CMS-Al2O3) Membranes
This work shows mixed matrix inorganic membranes prepared by the vacuum-assisted impregnation method, where phenolic resin precursors filled the pore of α-alumina substrates. Upon carbonisation, the phenolic resin decomposed into several fragments derived from the backbone of the resin matrix. The final stages of decomposition (>650 °C) led to a formation of carbon molecular sieve (CMS) structu...
متن کاملRecent Advances on Carbon Molecular Sieve Membranes (CMSMs) and Reactors
Carbon molecular sieve membranes (CMSMs) are an important alternative for gas separation because of their ease of manufacture, high selectivity due to molecular sieve separation, and high permeance. The integration of separation by membranes and reaction in only one unit lead to a high degree of process integration/intensification, with associated benefits of increased energy, production effici...
متن کاملThe effects of suspending medium on dielectrophoretic systems for separating and sorting carbon nanotubes
The separation of two different types of multi-walled carbon nanotubes is studied in a dielectrophoresis-based microchannel system in seven different solvents as the suspending medium. A simple model was developed to predict the behavior of the multi-walled carbon nanotubes in the above mentioned system. Then, the equations of motion for the multi-walled carbon nanotubes in that system were in...
