Improvement of coke quality generally leads to increase of blending ratio of non- or slightly-caking coal in coal charge without deteriorating coke strength. Nippon Steel has developed dry coal charging process such as CMC and DAPS (Dry-Cleaned and Agglomerated Precompaction System) for cokemaking. Conventional cokemaking process has various disadvantages, such as the restriction on the coal brands that some proportion of strongly-coking coals has to be used as raw coal for cokemaking, low productivity, the inherent tendency to large-energy consumption, environmental pollution and so on. To solve these problems, development of the innovative cokemaking process, SCOPE21 (Super Coke Oven for Productivity and Environmental enhancement toward the 21st century) has been conducted by Japan Iron and Steel Federation (JISF) and Center for Coal Utilization Japan (CCUJ). This paper describes the R&D of coal pre-treating technologies for improving coke quality.
