Question

inctude coal, 20) Activated carbon is carbon produced from any carbonaceous source material. Some of the most common sources petroleum pitch, bamboo, coconut husk, wood, and even a variety of agricultural wastes. The source material is subject to an activation process to render a useful product. One of the two forms of activation processes consists of_ A) burning the material at 2300 °F. carbonizing the material in the absence of oxygen and then subjecting it to a very high temperature steam. (C) crushing the material to yield a granular or pulverized product, then burning it at 2300 F. (D) subjecting the material to steam at 2300

Explanation / Answer

option (B) is right

Carbonization is the process of taking a carbon-rich piece of material and converting it to pure carbon through heating.

Very dense carbonaceous material is used in the beginning, because the end result needs to be extra-porous. Carbon-rich material is placed in a small (relative to the amount of material) furnace and cooked at extreme temperatures topping 2000 degrees Celsius.end product is only 20-30 percent of initial weight.
