Activated carbon preparation with the addition of coke ...

Using coke powder for AC production is one of the ways to reuse coke powder. Alkali activation is the typical method for preparing AC from coke powder. As a product from coal pyrolysis at 950–1050 °C, coke powder is chemically inert, and the activation requires a large amount of alkali.

Sep 10, 2016 · ABSTRACTIn this study weathering was carried out for coals (source wise) in open piles at the Bhilai Steel Plant (BSP). Imported hard coals were selected for these studies. Several methods such as alkali extraction test, measurement of the free-swelling index, and the pH of the coal slurry have been applied to monitor coal weathering. These tests suggest that the pH of the coal slurry and ...

It was found that the optimum CC preparation temperature was 250 °C (CC250) for high strength coke preparation. 4. Whereas increasing the blending ratio of CC250 to caking-coal decreased the coke strength, the extent of the decreasing strength was smaller than that of slightly-caking coal or pyrolyzed char blended with caking coal. 5.

Coke (fuel) - Infogalactic: the planetary knowledge core

Coke is a fuel with few impurities and a high carbon content, usually made from coal.It is the solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal.Cokes made from coal are grey, hard, and porous.While coke can be formed naturally, the commonly used form is man-made. The form known as petroleum coke, or pet coke, is derived from oil refinery ...
