Preparing metallurgical fuel briquets from non-caking coal by preshrinking char

Claim 1

THE METHOD OF PREPARING METALLURGICAL FUEL BRIQUETS WHICH COMPRISES CARBONIZING A NON-CAKING COAL IN A FLUIDIZED STATE AT A LOW TEMPERATURE UNTIL SUBSTANTIALLY COMPLETE EVOLUTION OF TAR HAS OCCURRED, WHEREBY A PARTICULATE CHAR IS OBTAINED AS A RESIDUE, HEATING SAID CHAR IN PRATICULATE FORM AS A SUSPENSION IN HOT GASES TO AN ELEVATED TEMPERATURE ABOVE THE CARBONIZATION TEMPERATURE AT WHICH SAID CHAR WAS GENERATED TO EFFECT SHRINKAGE OF SAID CHAR, PASSING SAID HEATED CHAR AT SAID ELEVATED TEMPERATURE AS A DILUTE PHASE SUSPENSION THROUGH A COKING ZONE IN HEAT EXCHANGE RELATION WITH RAW BRIQUETS WHEREBY SAID BRIQUETS ARE COKED, RECOVERING CHAR FROM THE COOLED DILUTE PHASE SUSPENSION, FORMING RAW BRIQUETS FROM SAID CHAR FOR TRANSFER TO SAID COKING ZONE, AND RECOVERING COKED BRIQUETS FROM SAID COKING ZONE.

Claim 2

THE METHOD OF PREPARING METALLURGICAL FUEL BRIQUETS WHICH COMPRISES CARBONIZING A NON-CAKING COAL IN A FLUIDIZED STATE AT A LOW TEMPERATURE UNTIL SUBSTANTIALLY COMPLETE EVOLUTION OF TAR HAS OCCURRED, WHEREBY A PARTICULATE CHAR IS OBTAINED AS A RESIDUE, HEATING SAID CHAR IN PRATICULATE FORM AS A SUSPENSION IN HOT GASES TO AN ELEVATED TEMPERATURE ABOVE THE CARBONIZATION TEMPERATURE AT WHICH SAID CHAR WAS GENERATED TO EFFECT SHRINKAGE OF SAID CHAR, PASSING SAID HEATED CHAR AT SAID ELEVATED TEMPERATURE AS A DILUTE PHASE SUSPENSION THROUGH A COKING ZONE IN HEAT EXCHANGE RELATION WITH RAW BRIQUETS WHEREBY SAID BRIQUETS ARE COKED, RECOVERING CHAR FROM THE COOLED DILUTE PHASE SUSPENSION, FORMING RAW BRIQUETS FROM SAID CHAR FOR TRANSFER TO SAID COKING ZONE, AND RECOVERING COKED BRIQUETS FROM SAID COKING ZONE.
