Carbonaceous pellets and method of pelletizing

Patent ·
OSTI ID:6625334

A method is claimed for pelletizing carbonaceous materials including bonding coal fines and lignite coal with a polymeric hydrocarbon binder having reactive sites thereon. For example, with tall oil pitch and the like, in the case of coal, the binder is applied by slurrying the fine coal with the pitch. In the case of lignite, the binder is directly applied to the pulverized material. By action of rolling and tumbling, for example, large agglomerates are formed. With drying and heating, strong water-resistant pellets are formed which have the extremely desirable property of being easily repulverized.
