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
Gasification rates of a Texas lignite char, having calcium contents varying from 1.1 to 12.9wt%, were measured in air, steam, CO,, and H,. Gasification rates increased rectilinearly with increase in calcium loading. The chemisorption of CO, at 298 K on the CaO present on the char surface was used to
