Calcining of Green Petroleum Coke(GPC) is used as a source of high purity carbon. Depending on certain physical and chemical properties, GPC can be upgraded by calcination. The starting material, GPC is a high molecular weight polymetric hydrocarbon which thermally decomposes on calcining to form carbon, light hydrocarbon gases and hydrogen. Calcining is the heat treating process of removing moisture and volatile matter in a reduction atmosphere thereby changing the crystal structure and increasing the bulk density and electrical conductivity of the coke. After calcination, the Calcined Petroleum Coke (CPC) is used as the main carbon source for anodes in aluminum smelting. Other uses of CPC are in the production of titaniumdioxide and steel using electric arc furnace manufacturing.   © Copyright 2007 RCL. All Rights Reserved
