Measurements of the leachability of potentially hazardous trace elements from solid coal gasification wastes in China.
TL;DR: The cumulative leached concentrations of the potentially hazardous trace elements from the coal gasification residues were generally low, and only Mo in the leachate of GSP fine residue was moderately soluble, indicating that the potential for environmental pollution by those elements fromcoal gasification plants should be given consideration.

Fate of potentially hazardous trace elements during the entrained-flow coal gasification processes in China.
TL;DR: In some cases, Cr6+, Zn, As, Se, Cd, and Pb in the original wastewater samples exceed the limit for industrial use as indicated in the Chinese Environmental Quality Standards for Surface Water and the Emission Standard for Pollutants from Coal Industry.

Evaluation of carbon forms and elements composition in coal gasification solid residues and their potential utilization from a view of coal geology.
TL;DR: Evaluation of carbon forms and elemental composition in coal gasification solid residues from three advanced commercial-scale entrained-flow gasification plants in China related to feedstock coal properties are studied and their potential utilization is discussed.

Changes and Distribution of Modes of Occurrence of Seventeen Potentially-Hazardous Trace Elements during Entrained Flow Gasification of Coals from Ningdong, China
TL;DR: In this paper, the modes of occurrence of potentiallyhazardous trace elements (Be, V, Cr, Co, Ni, Cu, Zn, As, Se, Mo, Cd, Sb, Ba, Hg, Tl, Pb, and U) were determined by a five-step sequential chemical extraction procedure.

Behavior of trace elements and mineral transformations in the super-high organic sulfur Ganhe coal during gasification
TL;DR: A coal containing high concentrations of hazardous trace elements F, V, Cr, Se, Mo, Cd, and U was selected for the gasification experiment based on the Lurgi fixed-bed pressurized gasifier as mentioned in this paper.
