After the first oil crisis in 1973, Japan initiated research and development in coal liquefaction as a national project under the Sunshine Program. The goal of this project was to create commercially viable direct coal liquefaction technologies. New Energy and Industrial Technology Development Organization (NEDO) was established in 1980 and has been promoting a series of coal liquefaction projects ranging from basic research to process demonstration at a pilot plant. A new process, NEDOL process, was designed in 1983 based on three kinds of bituminous coal liquefaction processes! direct liquefaction, solvent extraction, and solvolysis. A NEDOL type pilot plant with daily capacity of 150 tons as coal was constructed and it was operated for three years from 1996 to 1998. The coal liquefaction project has also focused on the development of upgrading technologies for coal-derived oil to raise the quality level. In 1999 a process development unit (PDU) was built to demonstrate the upgrading process. The capacity of PDU was 40 b/d. The final products obtained from the PDU were blended with petroleum stocks, and provided for end-use evaluation tests including engine combustion performance and storage stability. In addition, the final products blended with petroleum stocks met all of the specifications for Japan Industrial Standard (TIS).
