BLACK BEAR CARBON

Carbon black is a form of elemental carbon that is manufactured by the controlled vapour-phase pyrolysis and partial combustion of hydrocarbons. Several processes have been used to produce carbon black, including the oil-furnace, impingement (channel), lampblack, thermal (decomposition of natural gas) and acetylene (decomposition) processes. Carbon blacks are commonly referred to by the process or the source material from which they are made, e.g. furnace black, lampblack, thermal black, acet... ylene black and channel black. The different grades from the various processes have certain unique characteristics, but it is now possible to produce reasonable approximations of most of these grades using the oil-furnace process, by which more than 95% of the total output of carbon black is produced.More
