TL;DR: In this article, it was observed that some chars gasify in what appears to be two steps and it is possible to fit the two-step data by use of a simple model that fits the continuous weight loss data well by assuming parallel gasification of two chars of different reactivities.
Abstract: In this study, chars produced by flash pyrolysis or hydropyrolysis of low-rank Canadian coals were gasified in an air atmosphere using the temperature-programmed-reaction (TPR) method. It was observed that some chars gasify in what appears to be two steps. It is possible to fit the two-step data by use of a simple model that fits the continuous weight loss data well by assuming parallel gasification of two chars of different reactivities. It seems likely that two-step gasification indicates chars of nonuniform reactivity or uneven ash distribution

TL;DR: In this article, the effect of synthesis gas as a potential reductant for a brown coal (Morwell) was compared with pure hydrogen and pure carbon monoxide using hydrogenated anthracene oil as solvent and a catalyst comprising 3% iron ore and 1% sulphur.

TL;DR: In this article, the authors show that the addition of effective catalysts results in enhanced reactivity of the coal to oxygen and steam; experimental data show high yield of H 2 from char and steam, and accompanying post-gasification chemistry.

TL;DR: In this article, Dispersion of disposable iron as a catalyst precursor was investigated to improve the catalytic activity in the liquefaction of a subbituminous coal and showed a significant increase in total conversion and oil yield in the presence of a sulphur source.
