摘要：
An experimental study to evaluate the influence of the process conditions on the reduction of tar generated during sewage sludge pyrolysis in a rotary kiln is presented. An indirectly heated rotary kiln at laboratory scale was used (4 kg/h). The influence of final temperature and residence time of the volatile phase in the rotary kiln on tar production were investigated. Product and energy distributions, as well as the composition of the generated tars were determined. Efficiencies in tar reduction in the gas phase between 17 and 71 % (in mass fractions) were achieved. The results of this work contribute to the explanation of the sewage sludge pyrolysis in an indirectly rotary kiln to promote the secondary reactions for tar conversion and the quality of the gas.
