Development of the innovative cokemaking process, SCOPE21 (Super Coke Oven for Productivity and Environmental enhancement toward the 21st century), had been conducted by the Japan Iron and Steel Federation (J1SF) and the Center for Coal Utilization Japan (CCUJ). It had been performed from 1994 to 2003 as a ten-year research program. Some technologies for the SCOPE21 process had been developed to realize the following concepts, i. e. (1) Effective use of coal resources (2) High productivity (3) Energy saving (4) Environmental protection In 2002 the program was in the last stage of a pilot plant test to confirm the functions of the SCOPE21 process and to collect the scale-up data for designing a commercial plant. The pilot plant consists of a 6t-coal/h coal pretreatment facility and a coke oven with its chamber volume of 27 m^3. The specifications of the coal pretreatment facility were determined based on the test results of a 0.6t-coal/h bench scale plant. The pilot plant was successfully operated on schedule for about one year until March 2003. The concepts of the SCOPE21 process were verified and the engineering data for designing a commercial plant were collected at the same time. Furthermore, the feasibility study was executed according to the results.
