UNITED STATES PATENT APPLICATION BY: CARL E. ECKMAN FOR: PROCESS FOR FORMING COAL-OIL MIXTURES UNDER SELECTED CON- DITIONS OF TEMPERATURE AND SHEAR ABSTRACT OF THE DISCLOSURE An improved technique is provided for forming coal into a stabilized coal-oil mixture. Coal, in a fine mesh size, is admixed with oil, a monomeric compound, a reaction initiator and a reaction catalyst at elevated temperatures and under a condition of low shear. The coal mixture is thereafter immedi- ately subjected to a condition of high shear at the maintained elevated temperature. The mixture is then admixed with a gelling agent to form a stable coal-oil mixture. According to the technique, coal of significantly greater water content than heretofore thought acceptable, is formed to a stable coal-oil mixture in a ready manner. In addition, the amount of monomeric compound heretofore thought needed to form the desired stable mixture is substantially reduced, resulting in improved process efficiency.
