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.
Claims2
An aqueous, pumpable composition having a viscosity at ambient temperature below about 20,000 cPs consisting of a carbonaceous solid consisting of particles less than 177 microns in size wherein the carbonaceous solid is selected from the group consisting of coke, DUA rock, and mixtures of DUA rock and coke, an aqueous treatment solution consisting of water and a water soluble polymer capable of viscosifying water, the polymer being present in an amount ranging from 10 to 500 ppm, wherein the concentration of the carbonaceous solid in the treatment solution ranges from 40 wt. % to 70 wt. % based on the weight of the carbonaceous material and water.
