Investigation on the sulfur occurrence and transformation during pyrolysis in the flotation fraction of high organic sulfur coal

摘要

1. Fraction D1 of with density of -1.30 g/cm~3 was dominated, and the sulfur was enriched in this fraction. 2. Sulfur occurrence in the flotation fraction is difference, organic sulfur mainly exists in low density fraction, while inorganic sulfur was mainly enriched in the form of pyrite in high density fraction.
