“…Owing to the relatively low energy requirements (no phase changes), smaller footprint, reduced environmental impact (no toxic solvents), easier operation (no moving parts or liquid flow problems), no corrosion issues and inherent modularity (constant contact area), polymer‐based carbon membrane has been considered to be a promising technique for CO 2 capture 4‐8. According to Baker,9 one of the current membrane markets is dominated by natural gas purification.…”

Carbon hollow fiber membranes (CHFMs) derived from polymer blend of polyetherimide (PEI) and polyvinylpyrrolidone (PVP) were extensively prepared through stabilization under air atmosphere followed by carbonization under N2 atmosphere. The effects of the stabilization temperature on the morphological structure, chemical structure, and gas permeation properties were investigated thoroughly by means of scanning electron microscopy, Fourier transform infrared spectroscopy, and single gas permeation system. The experiment results indicate that the transport mechanism of small gas molecules of N2, CO2, and CH4 is dominated by the molecular sieving effect. Based on morphological structure and gas permeation properties, an optimum stabilization condition for the preparation of CHFM derived from PEI/PVP was found at 300°C under air atmosphere. The selectivity of ˜55 and 41 for CO2/CH4 and CO2/N2, respectively, were obtained for CHFMs prepared at stabilization temperature of 300°C. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

“…Peaks were observed at 2q = 20° to 25° and another weak peak at 2q = 42° to 45° was attributed to (002) peak and (100) peak, respectively [23]. The (002) peak is derived from spacing between graphite sheets and (100) peak is related to the distance between carbon atoms within a graphite sheet [24].…”

Concerns about the impact of greenhouse gas have driven the development of new separation technology to meet CO2 emission reduction targets. Membrane-based technologies using carbon membranes that are able to separate CO2 efficiently appears to be a competitive method. This research was focused on the development of carbon membranes derived from polymer blend of polyetherimide and polyethylene glycol to separate CO2 rendering it suitable to be used in many applications such as landfill gas purification, CO2 removal from natural gas or flue gas streams. Carbonization process was conducted at temperature of 923 K and 2 h of soaking time. To enhance membrane separation properties, pore structure was tailored by varying the carbonization heating rates to 1, 3, 5, and 7 K / min. The effect of carbonization heating rate on the separation performance was investigated by single gas permeabilities using CO2 , N2 , and CH4 at room temperature. Carbonization heating rate of 1 K / min produced carbon membrane with the most CO2 / N2 and CO2 / CH4 selectivity of 38 and 64, respectively, with the CO2 permeability of 211 barrer. Therefore, carbonization needs to be carried out at sufficiently slow heating rates to avoid significant loss of selectivity of the derived carbon membranes.

CMS resulted in ultra-microporous membranes showing a classical molecular sieving structure as gas permeation was high for smaller molecular gas (H 2 ), which then decreased sequentially as the molecular sizes increased in the order of CO 2 , O 2 and N 2 . An important relationship was found when the intrinsic viscosity of the PAA precursor decreased from 1.66 to 0.65 dl g -1 , the ideal gas selectivity jumped to higher values such as from 101.8 to 163.1 for H 2 /N 2 , from 21.5 to 34.6 for CO 2 /N 2 and from 6.7 to 10.7 for O 2 /N 2 while the permeability decreased such as from 1816 to 1487 Barrer for H 2 , from 383.4 to 314.8 Barrer for CO 2 , from 119.0 to 97.7 Barrer for O 2 , from 17.8 to 9.1 Barrer for N 2 . The low intrinsic viscosity conferred a superior pore size control of the CMS structure, with an average ultramicropore size around 3Å. The O 2 /N 2 and H 2 /N 2 ideal selectivity versus permeability results were all above the Robeson's upper bound line, thus demonstrating the effect of low intrinsic viscosity precursors in  Corresponding author.
