Importance of volatile–char interactions during the pyrolysis and gasification of low-rank fuels – A review
TLDR
The volatile-char interactions can very significantly affect almost every aspect of low-rank fuel gasification, including the volatilisation of alkali and alkaline earth metallic species, the evolution of char structure, the dispersion of inherent catalysts and thus the reactivity of char.About:

Release and transformation characteristics of K and Cl during straw torrefaction and mild pyrolysis
TL;DR: In this paper, the authors investigated the release and transformation characteristics of K and Cl during straw torrefaction and mild pyrolysis under different conditions and found that the release ratio of Cl increased continuously with temperature and holding time and the release of Cl was linearly proportional to devolatilization.
