摘要：NOVELTY - Oily sludge aqueous coke slurry comprises 50-75 wt.% petroleum coke, 0.1-15 wt.% oily sludge, 0.001-1 wt.% dispersant, 0-1 wt.% oily sludge modifying agent and water (balance). The dispersant is naphthalene sulfonate, carboxylic acid, humic acid and/or ligno sulfonate. The oily sludge modifying agent is divalent or trivalent iron, and aluminum or calcium metal ion. USE - Used as oily sludge aqueous coke slurry. ADVANTAGE - The slurry has high calorific value, liquidity and stability; is easy to store and transport, can be used as combustion or gasification raw material, and has large scale application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing oily sludge aqueous coke slurry, comprising (i) mixing oily sludge and oily sludge modifying agent and stirring, adding water to dilute, preparing modified sludge mixed solution, (ii) adding petroleum coke, dispersing agent and modified sludge mixed solution into a grinding mill, where the solid particle grain size is not greater than 0.5 mm.
