Gadsby and co-workers (63) report that for a coal charcoal, the rate of the carbon-steam reaction is greater by a factor of about three than the carbon-carbon dioxide reaction at 800° and a pressure range of 50 to 500 mm. Hg. The results of Pilcher et al. (68) and Walker et al. (85), using the same graphitized carbon rods and apparatus, essentially agree with this finding. At 1100°, the former workers report a reaction rate of 1.6 g./hr. at a steam partial pressure of 142 mm. Hg, which can be extrapolated to 4.8...

The oxidation of carbon materials such as coal, charcoal, or graphite has been investigated for decades, and is well known as a powerful route to modify the physical and chemical properties of carbon materials. While the reaction of oxygen with carbon surfaces is one of the simplest reactions involving elemental carbon, it... 

Again, some of the old formulas call for coke, cinders or coal, charcoal, blood, hair or leather to add more carbon to the potassium carbonate. So just use five parts of whichever you want- I would choose charcoal but you could get scrap leather from any shoe shop, chop it in small bits and stir it in. The parts referred to mean parts by weight.

Carbon souree Virtually any carbon source seems to produee PCDD/F via the de novo route, ineluding activated earbon, coal, charcoal, and soot. 

Discussion Carbon does not possess a single set of properties as do hydrogen and chlorine, but three very different sets. A given sample is called diamond, graphite, or amorphous carbon, according to which set of properties it possesses. The specimens of amorphous carbon which are familiar have all been formed by the decomposition of compounds of carbon, often mixed with other substances, and so are seldom pure. The differences in the methods of formation and the presence of the impurities make the amorphous carbon from different sources appear to have dift erent properties, as in the case of coal, charcoal, and soot but when the pure carbon is extracted from these substances, it is all found to be the same. 

Coal, charcoal, graphite, and diamonds were all known in prehistoric times, but they probably were not recognized as all being forms of the same element—carbon. Ancient civilizations were most likely to use...

Heating wood in the absaice of air produces charcoal. Like coal, charcoal contains a high amount of amorphous fiee carbon and is used as a common fuel for outdoor cooking grills. Charcoal retains the general overall shape of the original wood, but the process oeates...
