Abstract

In this work, the pyrolysis characteristics and release of sulphur contaminant were studied under different mass percentages (25%, 50% and 75%) of Zhundong coal in the sample mixtures. The results showed that the yields of volatile products during co-pyrolysis were higher than those calculated from linear combination of corresponding yields of pure sludge and Zhundong coal, which mean that a certain synergistic effect occurs in co-pyrolysis process. The yields of H2S, COS and SO2 decreased with the increase in the content of Zhundong coal in the samples. What’s more, when the content of Zhundong coal were 50%, a great significance on the yields of sulphur contaminant occurs in the process of co-pyrolysis.
