Carbon products are obtained by heating coal (to give coke), natural gas (to give blacks), or carbonaceous material of vegetable or animal origin, such aswoodor bone (to give charcoal), at elevated temperatures in the presence of insufficient oxygen to allowcombustion. The volatile by-products...

All types of biomass receive their energy, directly or indirectly, from photosynthesis, during which plants con...
1. Carbon black is the amorphous allotrope (noncrystal form) of carbon. It is produced byheating coal at high temperatures (producing coke); burning natural gas (producing jetblack); or burning vegetable or animal matter (such as wood and bone), at high temperatureswith insufficient oxygen, ...
Almost all carbonaceous materials, either animal, vegetable; or mineral in origin i.e.; blood, bones, saw dust, coal etc., can be converted into activated carbon if treated properly. Among these wood, peat and lignin (paper will waste) are commonly used for decolorizing materials. Bone ...
