Four petroleum cokes were studied, and they showed completely different slurryability. The solid concentration at fixed viscosity (i.e. apparent viscosity of 1000 mPa) (SCFV) of four PCWSs is different from each other, with the highest value of 70.9%, and lowest of 62.1%. The apparent viscosity of the four PCWSs all increased with an increase of the solid concentration. The results showed that the PSD, inherent moisture content, specific surface area and pore volume of petroleum coke were key factors to affect the slurryability. The slurryability was enhanced with increasing PSD range and particle packing fraction, and with decreasing inherent moisture content, specific surface area and pore volume. 关键词：石油焦成浆化学性质表观粘度物理固体浓度水分含量比表面积
