Carbon disulfide process

Claim 1

A PROCESS FOR PRODUCING CARBON DISULFIDE WHICH COMPRISES INTRODUCING SULFUR VAPOR AND A FINELY REACTIVE CARBON COMPOSITION COMPRISING SULFUR, CARBON AND HYDROGEN IN CHEMICAL COMBINATION INTO A REACTION ZONE MAINTAINED AT 1100-1800* F., THE CARBON OF SAID COMPOSITION BEING CAPABLE OF BEING CONVERTED TO CARBON DISULFIDE TO THE EXTENT OF AT LEAST 95%, MAINTAINING THE COMPOSITION IN FLUIDIZED CONDITION BY MEANS OF SULFUR VAPOR, VAPORS FORMED DURING THE REACTION, AND GASES INTRODUCED AS HEREINAFTER SET FORTH UNDER CONDITIONS OF GAS VELOCITY TO FORM A DENSE PHASE AND A LIGHT PHASE OF SUSPENDED PARTICLES IN SAID REACTION ZONE, SEPARATING VAPORS CONTAINING CARBON DISULFIDE, ELEMENTAL SULFUR AND HYDROGEN SULFIDE, REMOVING SOLIDS THEREFROM, COOLING THE VAPORS TO CONDENSE THE SULFUR AS A LIQUID, SEPARATING AND RECYCLING THE LIQUID SULFUR, RECOVERING THE CARBON DISULFIDE FROM THE SUBSTANTIALLY SULFUR FREE VAPORS, CONVERTING HYDROGEN SULFIDE IN THE VAPORS FROM THE LAST NAMED STEP INTO ELEMENTAL SURFUR, AND PASSING AT LEAST A PORTION OF THE RESULTING GAS TO THE REACTION ZONE TO ASSIST IN MAINTAINING THE PARTICLES OF SAID CARBON COMPOSITION IN FLUIDIZED FORM AS ABOVE SET FORTH.
