Abstract:Coal liquefaction processes provide a basis to transform a solid into liquid fuels that are suitable for transportation purposes but release a wide range of air emissions, water effluents, and solid wastes, with considerable potential for locally reducing environmental quality. Compared with other major sources of emissions such as coal-fired power-plants, liquefaction plants release relatively low levels of emissions of sulphur dioxide and nitrogen oxides for an equivalent quantity of coal-feed. However, coal… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
