“…The activated carbon obtained at 700 • C characterized by an average pore diameter of 38.8Å is seen to have a marginal increase in pore diameter of 39.36Å at 800 • C. The narrow increase in pore diameter suggest that at 800 • C, certain unorganized carbons or residual tar materials were expelled by opening of closed pores [13] and existing pores, widened into larger pores of small magnitude through gasification of carbons in the pore walls having labile carbon structure [10]. The decrease in the pore diameter of C900 is due to the suppression of the pore widening of stable carbon structures [14] formed during precarbonization process and coalescence of pores in the carbon matrices.…”

“…In the case of RF the polymer with the highest char yield is polyethylene terephthalate which hass an isotropic structure [39]. Disordered carbon reacts more quickly than well ordered, more graphitic carbon [38,40]. Blends with coal were the slowest samples because coal required more time to be activated, since it is a less reactive material.…”

Tyre wastes and their blends with coal and a bituminous waste material obtained from the benzol distillation column of the by-product section of a coking plant were employed as a precursor for the production of activated carbons (ACs). Pyrolysis up to 850 °C followed by physical activation with CO 2 yielded mesoporous carbons with different pore size distributions and surface areas depending on the degree of burn-off. ACs with surface areas of 475 and 390 m 2 /g were obtained for the two tyre wastes. The inclusion of coal in the blend gave rise to surface areas of up to 1120 m 2 /g due to an increase in the microporosity.The time needed to obtain the desired degree of burn-off depended on the reactivity of the char. The coal-containing materials required the longest amount of time. The surface chemistry of the samples was studied by Infrared spectroscopy (FTIR) and X-Ray photoelectron spectroscopy (XPS). The principal oxygenated groups found were quinones, lactones and carboxylic acids.

“…Marsh et al 37 suggested that the coarseness just begins at the brim or defective sites of the crystal. The cracks of such a graphitoidal structure are deprived by COz and evolved into pores.…”

SYNOPSISThree types of precursors of polyacrylonitrile (PAN) hollow fibers were used to produce activated carbon hollow fibers (ACHF). These precursors are different in the structure and composition. Characterization were performed including tensile strength, modulus, x-ray diffraction, pore size distribution, and surface area measurement for the resulting ACHF. The results show that the ACHF produced from the precursor with larger crystal size and dense structure has higher mechanical properties, whereas the ACHF from the precursor with smaller crystal size and porous structure has larger surface area and broader pore size distribution.
