In the study, pine pyrolysis gases containing rich tar was passed through the bed of sewage sludge char prepared at high temperature to explore the partial oxidation reforming characteristics of pyrolysis tar. Under the varying conditions of equivalence ratio (ER), residence times of 1.25, 2.5, and 3.75 s in the char bed, and reforming temperatures of 700, 800, and 900 degrees C, we investigated the variations of gas composition, tar conversion ratio, and components in reforming products. After the gases containing rich tar were reformed over the high-temperature char bed, the tar conversion ratio reached 95%. The suitable ER for the reforming process was about 0.05 and allowed the highest contents of H-2 and CO and a tar conversion ratio of 98.34%. The increase in the reforming temperature increased the percentages of H-2 and CO in syngas to some degree and significantly decreased the tar concentration in syngas. At 900 degrees C, the tar conversion ratio reached 99.19%, and the obtained tar mainly belonged to 2-3 ring polycyclic aromatic hydrocarbon compounds. In addition, at 800 degrees C and with an increase in the residence time, tar concentration could not be further decreased, and the concentration of light aromatics was gradually increased. Sewage sludge char showed specific application advantages in catalytic reforming of tar.
