A sewage sludge carbonized fuel sample was blended into pulverized bituminous coal and the co-gasification reactivity was discussed in this study. First, the mixed sample was pyrolyzed and the char sample was gasified with steam in a TGA at 800℃. The coal char reactivity was accelerated by the blending sewage sludge carbonized fuel. Alkali metal species should have an influence on the reactivity. Second, the mixed sample was gasified with CO_2 in a PDTF under the high-temperature and elevated-pressure condition which is similar to the conditions in an entrained flow gasifier. The distinguish synergy between coal and sewage sludge carbonized fuel was found in the carbon conversion during co-gasification, although the synergy was not found in the co-gasification of coal and woody biomass.
