Pyrolysis behaviors and product distributions of coal flotation sample separated by float and sink test
TL;DR: In this paper , a float-sink method was used in coal processing to separate mineral matter from coal and enrich macerals, and the results indicated that the releasing temperature of volatiles in pyrolysis of different coal samples is mainly in the range of 350-550 ℃ and the amount of volume decreases with the increase of flotation density.
