Adsorption characteristics of alkanes onto carbon nanotube bundles: Grand Canonical Monte Carlo simulation
نویسندگان
چکیده
The separation of alkanes is important for a range of applications such as oil refinement, filtration and gas separation. Carbon nanotubes, with their large surface area are highly promising for applications utilising alkane adsorption and separation. Rather than remaining isolated however, nanotubes tend to bundle together, and the adsorption properties of such bundles and subsequent potential for practical alkane separation is not yet entirely clear. For this reason, we have undertaken Grand Canonical Monte Carlo simulations in order to study the adsorption properties of alkanes on nanotube bundles. Our results show how precise control of temperature and pressure allows selective adsorption of certain alkanes, and we describe in detail the reasons behind this.

متن کاملAdsorption and separation of linear and branched alkanes on carbon nanotube bundles from configurational-bias Monte Carlo simulation
The adsorption and separation of linear C1-nC5 and branched C5 isomers alkanes on single-walled carbon nanotube bundles at 300 K have been studied using configurational-bias Monte Carlo simulation. For pure linear alkanes, the limiting adsorption properties at zero coverage exhibit a linear relation with the alkane carbon number; the long alkane is more adsorbed at low pressures, but the revers...
متن کاملQuasi-one and two-dimensional transitions of gases adsorbed on nanotube bundles
Grand canonical Monte Carlo simulations have been performed to determine the adsorption behavior of Ar and Kr atoms on the exterior surface of a rope (bundle) consisting of many carbon nanotubes. The computed adsorption isotherms reveal phase transitions associated with the successive creation of quasi-one dimensional lines of atoms near and parallel to the intersection of two adjacent nanotubes.
