Abstract:
A PROCESS FOR MAKING AGGLOMERATES FROM NON-CAKING OR WEAKLY CAKING COALS WHICH INCLUDES TUMBLING IN A ROTARY KILN, AT AN ELEVATED FORMING TEMPERATURE, CARBONACEOUS MATERIAL OBTAINED FROM THE COAL FEEDSTOCK AND A BINDER ALSO OBTAINED FROM THE COAL FEEDSTOCK TO FORM GREEN AGGLOMERATES. THE BINDER CONTAINS A NONDISTILLABLE COAL EX-
TRACT FRACTION WHICH IS FLUID AT THE FORMING TEMPERATURE IN THE KILN. THE NONDISTILLABLE COAL EXTRACT FRACTION IS OBTAINED BY SOLVENT EXTRACTION OF THE COAL FEEDSTOCK.
