Title: Aqueous coal slurry

Abstract

A principal object of the invention is the provision of an aqueous coal slurry containing a dispersant, which is of low-cost and which contains very low or no levels of sodium, potassium, sulfur and other contaminants. In connection with the foregoing object, it is an object of the invention to provide an aqueous slurry containing coal and dextrin as a dispersant and to provide a method of preparing an aqueous coal slurry which includes the step of adding an effective amount of dextrin as a dispersant. The invention consists of certain novel features and a combination of parts hereinafter fully described, and particularly pointed out in the appended claims. 6 tabs.
