• Petroleum coke
• Black liquor
• Slurryability
• Rheological properties

The purpose of this paper is to prepare the petroleum coke-water slurry with a maximal coke mass fraction and the superior slurry natures using black liquor as an additive. The variations of theological properties, contact angle, fluidity, stability and zeta potential of the coke-water slurry with different black liquor dosages were investigated. It was observed that the addition of a black liquor dosage around 1.0 wt.% of the petroleum coke remarkably improved the rheological properties, fluidity and stability of the slurry, and the slurry could hold a mass of petroleum coke as high as 70 wt.%. with the superior apparent viscosity, fluidity and stability available for practical utilization.
