Carbonization of oxidized mesophase pitches originating from petroleum and coal tar was examined by thermogravimetry, FT-i.r. spectroscopy, and quantitative analysis of evolved gases. Polymerization and condensation of aromatic rings through loss of aromatic hydrogen are shown to be major chemical r
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 650ยฐ
