Abstract：The purpose of this article is to enhance the stability of water coke slurry,two kinds of stabilizers was added into water coke slurry to investigate their effects on the apparent viscosity and stability of the slurry.Results show that the apparent viscosity of slurry increase from 873 mPa · s to 1 039 mPa · s and the ratio of water separation decrease from 11.61％ to 8.57％ when mixed A at the dose of 0.3％.Likewise,the apparent viscosity of slurry increase from 891 mPa · s to 1 187 mPa · s and the ratio of water separation decrease from 6.30％ to 3.45％ when mixed B at the same dose of 0.3％.Both of the two kinds of stabilizers can significantly improve the stability of the slurry and increase the apparent viscosity of slurry,while the ratio of water separation was decreased with gradually addition of two kinds of stabilizers.The effect of stability of B was better than A to the apparent viscosity and stability of slurry,which was lower by adding O.3％ B than that by adding 0.6％.
