摘要：
The feature of coal-sludge slurries(CSSs) were studied by mixing Shenhua coal and sewage sludge collected from Huainan sewage treatment plant. The results showed that, the rheological properties of CSSs prepared with the adding dosage from 0 to 15% were the shearing and diluting feature. With the adding dosages of the sludge increase, the apparent viscosity values increased and the maximum solid concentrations of CSSs decreased. Also, the gasification kinetics were studied by Thermogravimetry-Fourier Transform Infrared(TG-FTIR). The gasification starting temperatures and activation energy decreased with the adding dosages of the sludge increase, it indicated that the process was accelerated by sewage sludge.
