Abstract
The invention provides a process for comminuting coal or other fuel solids in a shear field, and for optionally coating the solids with catalysts for combustion, liquefaction, and or gasification during the milling process. The process further provides for control of water content in the solids may be controlled before, during and after the milling in order to obtain micronized solids with fine hydration layers. The output fuel solids from the process can burn at low temperatures, avoiding emissions of nitrogen oxides, and they also have improved properties for surfactant-free suspension in either water or oil media, as well as for liquefaction and gasification.
