The gasification reactivity and crystallite structure of Shenfu char were measured via thermogravimetric analysis (TGA) and X-ray diffraction technology (XRD) to investigate the catalytic effect of AAEM during CO₂ gasification. The interest was focused on effects of loading method (pyrolysis before loading or pyrolysis after loading), catalyst species (Na, K, Ca) and loading amount (1%, 3%, 5% on metal atom). For Na and K, the reactivity of char pyrolyzed before loading catalyst is better than that pyrolyzed after loading. The order of catalytic efficiency is Na~K >Ca. In addition, catalytic efficiency of AAEM catalyst increases with the increasing of loading amount. Catalyst addition inhibits the progress of char graphitizing during pyrolysis. The order of inhibition is K > Na > Ca, and the inhibition is enhanced with the increase of loading amount.
