In this research, two carbon structures silica nanohybrids Pickering emulsions were prepared. Graphite and activated carbon were carbon allotropes with different morphologies of laminar and spherical, respectively. The effect of carbon morphology investigated on the related silica nanohybrids Pickeringemulsions for C-EOR. Therefore, nanohybrids were prepared with graphite and activated carbon t...

Activated carbon fibers were prepared from liquefied wood through stream activation. The effects of activation temperature and time on the microstructure and surface functional groups of the liquefied wood activated carbon fibers (LWACFs) were studied using analysis of burning behavior, X-ray diffraction, nitrogen adsorption-desorption isotherms, Xray photoelectron spectroscopy, and SEM. The re...

the used activated carbon was derived from pine-cone and was used for the removal of acid black 1(ab1) and acid blue 113(ab113) dyes. a batch sorption study was carried out in order to obtain optimum isotherm model. the study showed the best fit of the adsorption isotherm data was obtained using the langmuir model for both dyes. the monolayer maximum saturation capacities of ab1 and ab113 dyes ...

background and objectives: because of toxical and hazardous properties of hexavalent chromium (cr(vi)), its removal by an economical and efficient method is necessary. the use of activated carbon, as an adsorbent, is a common and effective method for hexavalent chromium removal. thus the aim of this study was to produce granular and powdered activated carbon form peganum harmala and compare the...

in this research, rice husk and activated carbon adsorbents were used for removal of lead ion from aqueous solution at ph= 6. in the batch tests experimental parameters were studied, including contact time and initial metal ions concentration.survey of the equilibrium time at different concentration showed that equilibrium time is reduced with decrease of initial concentration of solution from ...

Highly microporous bio-based activated carbon fibers (ACFs) were prepared through a simple reactivation method. Sawdust, as the starting material, was liquefied and melt-spun to produce the precursor fibers. Then, the precursor fibers were activated by KOH and reactivated by steam. By varying the conditions of the two activation processes, the formation mechanism of the pore structure was studi...
