Coal & Energy Technology Department
The Coal & Energy Technology Department is developing energy conversion technologies, such as upgrading low-grade coal through dewatering and deashing, coal liquefaction and hydrocracking of heavy oil. It is striving to find ways to effectively use the world’s untapped natural resources and contribute to securing stable and diversified energy sources for Japan.
Coal & Energy: Upgraded brown coal; ash-less coal; highstrength coke production; heavy oil hydrocracking; coal liquefaction
Coal Liquefaction Process
![]()
Coal liquefaction process was developed to produce the transportation fuel by using the low rank coal mined widely in the world.
Heavy Oil Hydrocracking
![]()
Based on the coal liquefaction technology, the hydrocracking technology of ultra heavy oil such as tar sand has been developed.
Coal Upgrading Technology
![]()
For the beneficial utilization of low rank coal (sub bituminous coal and lignite) with high moisture content, UBC process Upgraded Brown Coal) has been developed to dewater the raw coal with high efficiency.

Ash Free Coal Production
![]()
An ash less coal (Hyper-coal) production technology has been developed by using the solvent that has good affinity with coal.
