The K&O,-catalysed steam gasification of coal chars, obtained by the Supercritical Gas Extraction (SGE) process, is studied. Kinetics experiments used a gravimetric technique at atmospheric pressure and at temperatures ranging from 700 to 800ยฐC. It was found that K&O, is an effective catalyst for st

The catalytic effects of Na,COs, NaHCO,, NaOH, NaNO, and NaCl on steam gasification of coal chars have been studied by gravimetric measurements at temperatures ranging from 600 to 750X and at atmospheric pressure. FT-i.r. studies were carried out to determine the nature of the catalyst-coal interact
