The aim of this research is studying the effects of Ge-doped on CO adsorption on the outer and inner surfaces of (6, 0) zigzag model of boron nitride nanotube (BNNTs) by using DFT theory. For this purpose, eight models of CO adsorption on the surfaces of BNNTs are considered. At first step, all structures were optimized at B3LYP and 6-31G (d) standard base set and then the electronic structure,...

Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evalu...

Nitrogen is among the essential industrial gases after oxygen and hydrogen commonly obtained through air separation process. Air one of gas processes in many chemical industries since it accounts for a substantial element production costs related sectors. In response to this increasing need, most areas investigation quest cost-effective energy-efficient processes. Different technologies nitroge...

The present invention relates to a nitrogen adsorbent having nitrogen selective adsorptivity by including an organic inorganic hybrid nanoporous material having a coordina tively unsaturated metal site with density of 0.2 mmol/g to 10 mmol/g in a skeleton, Surface or pore; and use thereof, Such as a device separating nitrogen from a gas mixture containing nitrogen and methane, a pressure Swing ...

Abstract At present, nitrogen production from air by pressure swing adsorption (PSA) is simulated almost exclusively at low product purity levels (< 99% N 2 ). However, with increasing global demand for highly purified gases provided energy-efficient separation processes the requirement either extensive experimental research in high-purity range or predictive computer simulations arises.
