PRODUCTION OF SPECIFIC HIGH DENSITY CARBONACEOUS MATERIAL

PURPOSE:To obtain a special carbonaceous material having a high density and processing characteristics by calcining the molded product of a mixture obtained by adding a carbonaceous powder satisfied with a specific condition originated from C-H when coke is kneaded with a binder. CONSTITUTION:A carbonaceous raw material is thermally treated to produce carbonaceous material powder having a volatile content of 3-30wt.%, an average particle size of 15-20mum and a toluene soluble content of 1-30wt.%. The product satisfied with one or more of eight conditions originated from the C-H in IR absorbance spectrum is selected from the thermal products. As the conditions, a ratio between the peak of an IR absorption spectrum originated from C-H at a place near to 2913cm based on 2935cm and 2860cm and the peak of an IR absorption spectrum originated from C=C at a place near to 1600cm- based on 1665cm and 1540cm is set to
