Activated coke can be classified into molding and powder types. Columnshaped activated coke (diameter of 5−9 mm) are often used, but they have some disadvantages, such as low utilization efficiency of inner surfaces, high internal diffusion resistance, complex manufacturing process. These disadvantages restrict its application.
Activated charcoal is a fine black powder made of coconut shells, coke, coal, olive pits and sawdust. These ingredients are activated at a very high temperature and so activated charcoal is porous and devoid of toxic substances which are usually present in barbecue charcoal.
Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminium industries and is particularly valuable because the electrodes must be replaced regularly. Needle coke is produced exclusively from either fluid catalytic cracking (FCC) decant oil or coal tar pitch.
Abstract. The functional and group composition and structure of β and α 2 fractions of mediumtemperature coal pitch fraction (in powder form) are investigated by methods such as elemental analysis, electron microscopy, IR spectroscopy, ESR, Xray diffraction analysis, derivatographic analysis, and chromatography and mass spectrometry. The morphology and structure of the coke residues from ...
Metcoke is made from low ash, low sulfur bituminous coal, with special coking properties. It is inserted into ovens and heated to 1000 ˚F to fuse fixed carbon and inherent ash and drive off most of the volatile matter. The final product is a nearly pure carbon source with sizes ranging from basketballs (foundry coke) to a fine powder (coke ...
Next, Meng et al. [35] showed that the tensile strength of coal coke was approximately MPa, which was lower than the BioCoke, which could be due to the microstructural features of the coal coke that contained pores. ...

The rapid and lowcost preparation of powder activated coke (PAC) is very important for the promotion of uidized dry desulfurization technology of activated coke. In order to explore the eect of rapid pyrolysis process on SO ... ing coal devolatilization (Chen et al. 2011; Xu et al. 2010). Through the research on the evolution of fractal dimen
Ferrocoke, as a new burden of blast furnace (BF), can not only greatly reduce the energy consumption and CO2 emission, but also promote the resource utilization by using the lowquality iron ore and lowgrade coal. However, the strength of ferrocoke decreased with the increasing amount of iron ore powder. In order to maintain the strength of ferrocoke while increasing the amount of iron ore ...
Coke is primarily used to smelt iron ore and other bearing materials in blast furnaces, acting both as a source of heat and as a chemical reducing agent to produce pig iron or hot metal. Richa Refractories currently operates non polluting non recovery type coke ovens.
Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
