Abstract
Both CO 2 and steam gasification kinetics were determined for Michigan Antrim shale char using TGA techniques in combination with on-line gas chromatography. While the reaction kinetic expressions were similar to those previously derived for Green River Formation (western USA) and Swedish Ranstad shale chars, the gasification rates were found to be on the same order as those of Ranstad char but significantly lower than those of western shale char. In addition, the gas produced from steam gasification was found to be significantly higher in CO than the corresponding gas from western shale char. This and the presence of significant quantities of CO 2 lower the attractiveness of Antrim char as a source of synthesis gas or hydrogen.
