Reactivity of coal gasification with steam and CO2

1998-12-1 · Coal reactivity decreases as coal rank increases. Miura et al. found that the gasification reactivity data of chars prepared from 68 different coals by different authors, were very scattered for low rank coals (%C<80), but the reactivity was higher than that obtained for higher rank coals.When carbon content was more than 80%, reactivity data were less scattered, but decreased as rank increased.
