Investigation on handling and cleaning of coals

石炭利用水素製造技術開発,石炭のハンドリング等に関する調査研究
Study period:1991 - 1993

Research overview:
The objectives of the research are to clarify handling and cleaning characteristics of lower rank coals, to analyze and evaluate an effect of coal cleaning, and to investigate an applicability of coal cleaning to gasification. Coal cleaning and evaluating techniques in this research include coal deashing by oil agglomeration using fossil fuels as bridging oil, reactivity of oil agglomerates for liquefaction and gassification, biodesulfurization and biodenitrification, pretreatment of coals by supercritical water, and advanced coal deashing process by froth flotation. For coal handling techniques, a simulation of spontaneous combustion and an evaluation of handleability are investigated.
