Abstract
Abstract
In this research work we aimed to graft lignin which a naturally oxygenated compound with different ratio of oxidized asphalt (contains synthetic oxygenated groups). Grafting aimed to allow the two type of the functional groups to react in the presence of small amount of base. The process conducted at 300 oC in the absence of air. Carbonization of the mixture was carried out in the presence of twice the amount of sodium hydroxide and at a temperature of 450-500 oC till no more gases evolved. The product carbon was activated by refluxing with 30% HCl. Evaluation of the activated carbon was conducted by adsorption of iodine and methylene blue. Other variables such as density, humidity, ash and surface area were also determined
