    The slurrying properties of slurry fuels made of petroleum

    Abstract Petroleum coke and petrochemical sludge are the two main by-products of the petroleum chemical industry. They can be disposed and utilized efficiently and cheaply in the form of petroleum coke–sludge slurry (PCSS). The high-quality slurry fuels of low viscosity and good stability can be prepared by petroleum coke and petrochemical sludge, making use of their complementary
