The slurryability

temperature performance

rheological characteristics and stability of petroleum coke water slurry (PCWS) were studied after adding different additives. The solid concentration of PCWS prepared with different additives was about 70% when the apparent viscosity was at a fixed value of 1000 mPa·s. The apparent viscosity of PCWS decreased as temperature became higher and increased as solid concentration increased. Rheological characteristics and stability of PCWS showed great difference with different additives. PCWS behaved as dilatant fluid and had bad stability with NSM and NC additives. However it behaved as pseudoplastic fluid and had good stability with LS and PS additives. The stability of PCWS became better when solid concentration increased.
