The char of the upgraded brown coal, which had been prepared by extracting Loy Yang brown coal with 1-methylnaphthalene, was gasified in CO_2 at pressures from 0.1 to 2.0MPa and temperatures from 1173 to 1473K using a direct-heating high pressure reactor. It was found that the reactivity of upgraded brown coal char was more than twice as high as that of original brown coal. However, other gasification properties such as effects of pressure, activation energies and the structural parameter Ψ in random pore model were similar to those of original coal char.
