The catalytic effects of a series of alkali metal salts in promoting the gasification of a graphite powder by carbon dioxide and water vapor have been studied by thermogravimetry between 700 and 1100Β°C. Lithium salts, specifically the carbonate and hydroxide, were the most active catalysts for both

After a reflection on the gasification-kinetics of alkali-doped coal the catalytic activities of Li, Na, K, Cs were compared. The behaviour of coke doped with alkali carbonate under inert atmosphere was also studied.
Alndrae-The aim of this part of the paper was to confirm by experimental results theoretically derived relationships for the calculation of true activation energies and the concentration of the various sites of carbon gasification as given in part I. For this purpose, the gasification kinetics of a
Previously it was shown that certain mixtures of K2S04 and FeSO, were excellent raw materials for catalytic watervapourgasification of carbon. It was suggested from the results that the iron salt catalyses the reduction of K2S04 to K as the main catalyticly active species of gasification. This paper
