In the previous study it was found that the nickel catalyst impregnated on brown coals shows excellent activity in the gasification reaction. In this study more cheap catalyst, Ca (OH) 2, was used as starting material. The chemical state during the steam gasification was determined and the reactivity was determined in the temperature range from 600 to 800°C. Ion-exchanged Ca was transformed to finely dispersed CaCO3 upon pyrolysis and the extensive crystal growth of CaCO3 was observed during… CONTINUE READING
