Abstract
A method of preparing a stabilized suspension of carbon in hydrocarbon fuel characterized by comminuting coal to form predetermined sized particles and coating the particles with at least a coating of an alcohol having 1-4 carbon atoms and thereafter admixing the alcohol coated particles with a liquid hydrocarbon to form the substantially uniform admixture for serving as a fuel. In a preferred embodiment, coal particles are first compacted and comminuted to the predetermined size range to form an abundance of platey, lenticular, irregular and angular particles for forming a stabilized suspensoid that exhibits the property of shear thinning so as to be pumpable with a lower apparent viscosity than the at rest viscosity of the slurry of carbon in hydrocarbon. Also disclosed are specific details of the method and preferred embodiments, including the fuel composition, per se.
