The kinetics of gasification of shale char from the Swedish Ranstad deposit have been investigated at atmospheric conditions in the temperature range 800-1000/degree/C by thermogravimetric analysis. The reaction rate of fixed carbon can be described by modified Langmuir-Hinshelwood expressions. Similar to coal, strong retarding effects of hydrogen and carbon monoxide were found. The catalytic effect of impregnation with potassium and calcium salts was found to be of minor importance in the temperature range 850-940/degree/C. 19 refs.
