CO, gasification of a gas-coal char catalysed by Na,C03 and K&O, was studied using a fixed-bed reactor at 79S102o"C and 0.2 MPa. The gasification rate increased with increasing temperature. With increasing addition of Na2C03 in the range 9-25 wt% and K&O, in the range 5-20 wt% the rate increased sha
The utilization of potassium as catalyst in coal steam gasification suffers due to difficulty in its quantitative recovery from gasification residues. This is due to the formation of non-leachable compounds with the mineral matter ofcoal. The reactivity of K,CO, with some mineral constituents ofcoal
