Abstract
Investigation into the coking behavior of heavy oil-coal blends was made by various means, including solvent extraction, volatile microstrength index (MSI) and polarized-light microscopic observations. Pitches were prepared from several heavy oils by heat treatment in a temperature range of 350-580 degree C. It was found that the pitches processed under critical conditions show swelling behaviors similar to those of coking coal during coking. Compatibility between the pitches and coking coals is recognized, but not in the case of non-coking coal blends. The results obtained show that heavy oil can be used in the manufacture of metallurgical coke.
