“…The most studied method is harnessing non-coking coal to replace part of coking coals, but the caking property of coal blends will deteriorate in such a situation. To improve the caking property, on the one hand, various high bond-ability substances, such as pitches, coal tar pitches, coal extracts, and solvent-refined coals, have been used in the carbonization process of coal blending with low bond-ability [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. On the other hand, non-coking coal was pretreated by thermal treatments [ 8 ], hydrothermal treatments [ 9 , 10 ], and steam treatments [ 11 , 12 ].…”
