A detailed study has been conducted of the effects of LiCI, NaCI, KCI, RbCI, CsCI, KOH, and K2CO3 on the steam gasification of char produced from a western sub-bituminous coal. Initial screening of results revealed that K2CO3 had the greatest catalytic activity for a fixed cation content in the char

## EXAFS spectroscopy and several supplementary techniques have been used to investigate a variety of coal and polymer chars containing alkali and alkaline earth catalysts, including Ca, K and Rb. In-situ EXAFS measurements were performed on Rb-loaded chars during gasification. At 450Β°C in 90% N,-

The catalytic activities of pure and mixed catalysts of alkali and transition metal salts in steam-char gasification at 700-850Β°C were measured with a thermobalance. The effects of catalyst loading (O-35 wt%) and composition, coal rank and steam partial pressure were determined. The initial rate inc
