The Mechanism of the Catalytic Gasification of Coal Char: A Critical Review
Bernard Wood,Kenneth M. Sancier +1 more
TL;DR: In this article, the authors present an overview of the available information on the mechanism of catalytic catalytic gasification catalyst action, and discuss the need to collate, summarize, and interpret this information.
Journal ArticleDOI
Catalytic effects observed during the co-gasification of coal and switchgrass
TL;DR: In this article, a series of CO2-char gasification tests were performed in a thermogravimetric analyzer (TGA) to evaluate the catalytic activity of alkali-rich biomass-derived materials.

K2CO3 catalyzed CO2 gasification of ash-free coal. Interactions of the catalyst with carbon in N2 and CO2 atmosphere
TL;DR: In this article, the interaction of K 2 CO 3 with ash-free coal in N 2 or CO 2 atmospheres was studied at 700°C by thermogravimetry and in situ X-ray diffraction.

Effect of iron on the gasification of Victorian brown coal with steam:enhancement of hydrogen production
TL;DR: In this paper, the authors reported the significant enhancement of hydrogen production during the gasification of Victorian brown coal with steam using iron as a catalyst and showed that the overall gasification rate of a char increases greatly in the presence of iron.

Steam gasification of German hard coal using alkaline catalysts: Effects of carbon burn-off and ash content
TL;DR: In this paper, experiments were performed on chars from German hard coals with potassium carbonate addition and the results indicated a complex interaction of catalytic gasification, catalyst deactivation, and the development of the reacting surface.
