Reforming of nascent volatile from the rapid pyrolysis of two kinds of coals(Loy Yang, Ly and Adaro, AD)over char prepared from the identical coals was studied at 900 °C. The reforming was very rapid and extensive for LY, allowing only benzene(0.02% on a coal C basis), naphthalene(0.001%), and phenanthrene(0.0001%)to escape from the char bed at an empty-bed gas residence time of less than 170 ms, whereas the reforming was less extensive for AD, exhibition 0.6% of tar yield. In reforming of the nascent tar from AD, influence of dilution of the char particle bed by mixing with silica sand was additionally studied. It was found that the dilution of the char particles had little influence on the reforming characteristics, suggesting that extensive tar reforming can likely be expected at the non-fixed bed reactor in which the solid hold-up is small.
