Fuel composition and method of manufacture. [Patnet]
An economical fuel composition is presented that can be readily transported and stored and that has good nonpollution properties characterized by a combustible, pseudo-thixotropic, liquid-solid suspensoid including a critical proportion of coal particles having a critical settling velocity substantially uniformly dispersed in a solution of methyl fuel including methanol, water and other alcohol-soluble constituents of the coal. The critically sized and shaped coal particles are worked in the presence of the methyl fuel to become wet along all surfaces, such that the coal particles are maintained in suspension by even low intensity stirring in storage and do not separate out upon flow through a pipe line. The suspensoid has shear thinning rheological properties so as to be pumpable with a lower apparent viscosity than its at-rest viscosity.
