Half of the world's coal resources are so-called low rank coal (LRC) such as lignite, sub-bituminous coal. Utilization of such coal is limited due to low heat value and high propensity of spontaneous combustion. Since some of LRC have advantages as clean coal; i.e. low ash and low sulfur content, LRC can be the excellent feedstock for power generation and metallurgy depending on the upgrading technology. The UBC (Upgraded Brown Coal) process introduced here converts LRC to solid fuel with high heat value and less propensity of self-heating. Various world coals, so as Australian, Indonesian arid USA LRC, were tested using Autoclave and Bench Scale Unit, and the process application to LRC of wide range is proven. The R&D activities of UBC process is introduced including demonstration project with 5ton/day test plant in progress in Indonesia, expecting near future commercialization in order to utilize abundant LRC of clean property.
