In this study activated carbons were prepared from three Australian bituminous coals. The influence of coal oxidation on the carbonization and activation processes and the structure of the resulting activated carbons were explored. The oxidation was conducted at 200Β°C in 0, for 6 hours. During the o
A series of activated carbons was prepared from bituminous coal by chemical activation with potassium hydroxide and zinc chloride and also by physical activation with carbon dioxide. The effect of process variables such as carbonization time, temperature, particle size, chemical agents, method of mi
Powdered activated carbon has been prepared from lignitic coal of Lakhra (Pakistan) by a chemical activation method using ZnCl, as an activating agent. Different process variables have been established after a series of experiments and an impregnation ratio of 1: 2, an activation temperature of 650Β°
