Evaluation of the microwave-assisted organic acid separation of organic sulfur from high-sulfur coal
Clean Technologies and Environmental Policy, 2021 Abstract To explore the feasibility of organic acid removal of organic sulfur from high sulfur coal, three organic acids, oxalic acid, citric acid and ascorbic acid, were selected as desulfurization reagents. Combined with microwave irradiation technology, desulfurization experiments of high-sulfur coal treated with nitric acid were conducted ...
