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

0 1 Solid fuels (derived solid fuels) The title method involves (a) the use of a faujasite type zeolite (SiOz/ AlzOs mol ratio = l-6) as an adsorbent, and (b) the use of a C&a aromatic hydrocarbon as eluent. The title method is useful for separation of benzothiophene from naphthalene in coal tar.
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 200°C in 0, for 6 hours. During the o
