The paper outlines a survey of the overall next generation coal utilization technology conducted by coal-related researchers in Japan. The studied subjects are as follows: as coal gasification/combustion combined cycle power generation process, technical survey of coal gasification and high efficiency power generation process, technical survey of research/development of topping combustion, oxidation mechanism of calcium sulfide and proposal of the char combustor, and evaluation of reaction activity of Ca-Mg based oxides upon high-temperature dry desulfurization. As to oxygen combustion, CO2 separation from flue gas from power generation plants. As coal thermal cracking technology, rapid thermal cracking, flash heating, pressurized fluidized bed catalytic thermal cracking, and catalytic reforming of thermal cracking volatile matter. Concerning advanced coal reforming technology, column flotation, nitrogen preremoval, liquefaction of low-grade coal using supercritical water, coal extraction using supercritical fluid, and utilization of coal as a solid radical catalyst. In addition, analyses of shapes of sulfur/nitrogen in desulfurization/denitrification and of crack growth in coking. 232 refs., 138 figs., 46 tabs.
