Steam activation of pelletized coal fines

الملخص EN

Waste coal fines were crushed, ground and then processed into 2.5 mm diameter pellets using sugar-cane molasses as a binder.

These pellets were charred at 600°C for two hours and then activated by dry superheated steam at different temperatures, steam flow rate and duration.

Specific surface area and crushing strength of the produced active carbon pellets were experimentally measured.

Optimum activation conditions were found to be: 800°C, 3 hours, and steam flow rate of 54 kg/hr.kg of coal.

Under these optimum operating conditions, the produced pellets have a specific surface area of 820 m2/gram and crushing strength of 180 grams/pellet.
