Abstract
The aim of this study was to analyse the steam gasification process of 'Janina' coal with and without Na-, K- and Ca-catalysts. The catalysts were physically mixed with the coal due to the simplicity of this method, short time of execution and certainty that the amount of catalyst is exactly as the adopted one. The isothermal measurements were performed at 800, 900 and 950 degrees C and a pressure of 1 MPa using thermovolumetric method. The obtained results enabled assessment of the effect of analysed catalysts on the pros at various temperatures by determination of: i) carbon conversion degree; ii) yield and composition of the resulting gas; and iii) kinetics of formation reactions of main gas components - CO and H-2. The addition of catalysts, as well as an increase in operating temperature, had a positive effect on the coal gasification process - reactions rates increased, and the process time was reduced.
