文摘
- •
The stable and active radicals generated in pyrolysis of 14 coals are quantified.
- •
The coals contain unconvertible radicals that are likely to be in fusinite.
- •
The amounts of bonds cleaved in coal pyrolysis decrease with increasing coal rank.
- •
The radicals generated in pyrolysis are 3 order of magnitude more than that in coal.
- •
The bonds cleavage in coal pyrolysis with DHP follows the 1st order kinetics.
