Conversion characteristics of tar model compounds have been investigated in simulated atmospheres that are likely happened in the reductors of air-blown and O_2/CO_2-blown two-stage entrained-flow coal gasifiers. A mixed vapor of model compounds; benzene and naphthalene, which are believed to be the most refractory aromatics, was thermally converted in an atmospheric tubular reactor at 1100-1400 ℃. Gas mixtures composed of CO-CO_2-H_2-H_2O and N_2 were used to simulate the reductor atmospheres. The experimental results suggested that O_2/CO_2-blown mode suppresses the soot formation and promotes the gasification of the soot and/or soot precursor more extensively than air-blown mode does over the entire range of the conditions.
