This study is concerned with the co-carbonization of coal-tar pitch with weak-coking coal mixtures for the production of high-strength metallurgical cokes for the blast furnace process. Several lab-scale testing methods have been applied to the pitch/coal blends including coking tests, ditatometry,
The extent of development of anisotropic texture in cokes prepared from various coals or blended coals in co-carbonization systems was assessed by using the ratio of hydrogen donor ability to acceptor ability. A parameter D/A, corresponding to the amount of hydrogen transfer during carbonization in
