- •
Two different rank coals with high organic sulfur content were pretreated by PCE extraction.
- •
Change of sulfur forms and their transformations during pyrolysis were investigated by combined GC-FPD, Raman and XAS.
- •
Changes of sulfur forms in coals and chars before and after PCE extraction are related to the rank of coal.
- •
PCE extraction is more suitable for the desulfurization of low rank coal.
- •
The sulfur is unevenly distributed on the surface and in bulk of coal.
