“…Although several changes are noted, the one of particular interest here is the appearance of a strong absorption band at 1700 cm-' and the intensifying of the band at 1625 cm-' relative to other absorptions. These two bands have been attributed by Higgins et al (19) Tang and Bacon (20) to C=O and C=C. Attempts were made to reduce the C=O using sodium borohydride.…”

Further evidence is presented to show that when cellulose is heated it undergoes two competitive reactions. The actual sequence of these is clarified, being different from that previously postulated. The natures of these reactions are studied, activation energies are determined, and their possible mechanisms are suggested. The thermogram for levoglucosan decomposition is given and briefly discussed.

In the present study, stabilized rayon fabrics were prepared from fast isothermal stabilization processes, which were carried out within four minutes at 350°C. The effects of ultrasonic cleaning and chemical pre-treatment on the chemical composition, physical characteristics, X-ray diffraction pattern, thermal stability and shape of the stabilized rayon fabrics were investigated extensively. In order to reduce the weight loss and thermal shrinkage of rayon fabrics occurring during the stabilization process, ultrasonic cleaning was first conducted and then chemical pre-treatments using NH4Cl, Na3PO4, H3PO4, and ZnCl2 were performed, respectively. The results indicated that both ultrasonic cleaning and chemical pre-treatment influenced the weight loss, thermal shrinkage, microstructure, carbon content, thermal stability and fabric shape of stabilized rayon fabrics. Also the results depended on the fast-stabilization time and the type of chemical pre-treatment agents used.

“…Since the 1970s, many types of synthetic and natural fibers has been used as precursors for fibrous activated carbon like polyacrylonitrile (PAN), 7 polyphenol, viscose rayon, 8,9 cellulose phosphate, phenolic, 10,11 and pitch based fibers. 12,13 Out of them, cellulosic polymer such as cotton, rayon and jute was more than ever focused, for the reason that of their low cost, commercial availability of precursor, high microporosity of prepared activated carbons and biodegradability of precursor.…”

In this study, activated carbon fabric was prepared from a cellulose-based polymer (viscose rayon) via a combination of physical and chemical activation (mixed activation) processes by means of CO 2 as a gasifying agent and surface and adsorption properties were evaluated. Experiments were performed to investigate the consequence of activation temperature (750, 800, 850 and 925 °C), activation time (15, 30, 45 and 60 minutes) and CO 2 flow rate (100, 200, 300 and 400 mL/min) on the surface and adsorption properties of ACF. The nitrogen adsorption isotherm at 77 K was measured and used for the determination of surface area, total pore volume, micropore volume, mesopore volume and pore size distribution using BET, t-plot, DR, BJH and DFT methods, respectively. It was observed that BET surface area and TPV increase with rising activation temperature and time due to the formation of new pores and the alteration of micropores into mesopores. It was also found that activation temperature dominantly affects the surface properties of ACF. The adsorption of iodine and CCl 4 onto ACF was investigated and both were found to correlate with surface area.
