Abstract

Activated carbon was prepared from the residual fixed carbon by the dry distillation of Khafji Crude Atmospheric Residue mixed with alkali as an activation agent, along with the reformed distillate (desulfurized, deasphalted and demetallified). The yield varied from 3 to 12% based on the Residue, depending on the condition of the dry distillation (at 450-650°C) and the amount of alkali (1/8-1/1 to the Residue). The liquid-phase adsorptive power of the activated carbon was estimated for caramel color (-99%), methylene blue (-450mg/g) and iodine (-1, 530mg/g). The prepared activated carbon and commercial activated carbons were tested for measurement of specific surface area, total pore volume, micro-pore volume and pore size distribution curve by the reported method2)-6). Also, the effect of alkali upon the formation of non-graphitizing carbon was shown by the X-ray diffraction measurement.
