Residual carbon from coal combustion is not the same as activated carbon. The pore structure, surface properties, and inorganic content may be strikingly different. Nonetheless, coal char does have some capacity for adsorbing mercury.  5, record 1, English, - char

[This residue] can be burned for its energy content or, if free from large amounts of impurities, processed further for production of activated carbon for use as a filtering medium. Char produced from coal is generally called coke, while that produced from wood or bone is called charcoal.  3, record 1, English, - char

Le noir de charbon se fait avec des morceaux de charbon bien nets et bien brûlés, que l'on pile dans un mortier, et que l'on broye ensuite à l'eau sur le porphyre, jusqu'à ce qu'il soit assez fin. Alors on le met sécher par petits morceaux, sur du papier bien lisse. C'est un très bon noir pour les tableaux, et également bon pour peindre à l'eau.  7, record 1, French, - produit%20de%20carbonisation

Le noir de charbon provient de la combustion d'un végétal à l'abri de l'air. C'est le plus ancien pigment que l'homme ait employé. Le choix des végétaux varie selon les époques et les artistes. Si le noir de charbon est rarement utilisé de nos jours, le fusain, obtenu par un procédé semblable, est pour sa part encore très prisé.  8, record 1, French, - produit%20de%20carbonisation

The indirect or retort method involves cooking the wood with a outside energy source to drive off the volatile gases and char the wood. A retort is simply any container that the wood goes in that can withstand the heat and allow the gases to escape.  3, record 2, English, - retort%20method

spouted bed gasifier.... a single-chamber air-fed gasifier operated on a cyclical basis, to yield a high calorific-value gas essentially uncontaminated by carbon dioxide or nitrogen. Wood chips or wood pellets are fed on top of a bed of hot sand in the reactor, and are then mixed by spouting the bed using steam. Some gasification occurs during this phase, but most takes place during the ensuing "cooking" phase during which the bed is static. When the temperature has fallen to a suitably low value air is admitted to burn the char and raise the temperature of the sand to its original value. Wood is then added to begin a new cycle.  1, record 4, English, - spouted%2Dbed%20gasifier

Record number: 5, Textual support number: 1 OBS

The use of biomass as a feedstock for the production of energy and chemicals has been a popular research topic over the past decade. One of the technologies receiving a great deal of attention is liquefaction in which biomass is converted to oil under high temperatures and pressures. This technology has evolved from a slow, chemical intensive process to a very rapid operation requiring little more than water. Feeling that typical reactor residence times(1-2 hours) were excessive, Beckman developed a small unit capable of reducing heat-up times to less than three minutes. Under these conditions it was found that neither a catalyst nor reducing gas was required. A mixture of only wood and water, when rapidly heated to 350°C, yielded an oil, char and gaseous and aqueous products.  1, record 5, English, - aqueous%20pyrolysis
