Significant increase of permeation flux and selectivity of poly(vinyl alcohol) membranes by incorporation of crystalline flake graphite

Diffusion behavior of benzene/cyclohexane molecules in poly(vinyl alcohol)-graphite hybrid membranes by molecular dynamics simulation

“…From the FFV results probed by benzene and cyclohexane in Table 3, the FFVs of PVA-graphite hybrid membranes are larger than that of PVA control membrane. The simulation results show the same tendency with the PALS (Peng et al, 2005a). And the FFV of hybrid membranes follows the order of CG3/PVA>CG2/PVA>CG1/PVA.…”

“…The dispersed inorganic particles in organic phase may improve the transport properties (Li et al, 2004;Peng et al, 2005a) of the membranes as well as mechanical (Liu and Wu, 2001;Sheng et al, 2004;Odegard et al, 2005) and thermal (Chen and Yang, 2002;Ash et al, 2002) properties. No doubt, understanding the effects of incorporated inorganic particles on transport properties of hybrid membranes is of great importance in choosing and designing membranes with tailored structure and desired properties.…”

Chitosan/TiO2 nanocomposite pervaporation membranes for ethanol dehydration

“…The pervaporation experiments were the same as those previously reported in the literature (Peng et al, 2005). The vacuum in the downstream side was maintained about 0.5 kPa using a vacuum pump, and the flow rate of feed was 60 L/h.…”

Efficient removal of benzene from cyclohexane-benzene mixtures using deep eutectic solvents – COSMO-RS screening and experimental validation

“…Traditional distillation is infeasible for the separation because of their close boiling points (DT b = 0.6°C at atmospheric pressure), approximately equal molecular volumes, and the binary azeotrope [3][4][5][6]. In the chemical industry, extractive distillation or azeotropic distillation is viable for the separation of benzene and cyclohexane; however, these processes are complex and consume a substantial amount of energy [1,2,6,7].…”
