Abstract
The invention is a method for forming a solid carbonaceous material into a pumpable fluid by combining the solid with an aqueous treatment solution and then subjecting the mixture to shearing forces. The solid carbonaceous material can be deasphalter unit rock ("DAU rock"), coke, and mixtures of DAU rock and coke. Aqueous treatment solutions contain a water soluble polymer.
