Method for effecting the conversion of organic reactant streams

Claim 1

A CONTINUOUS METHOD FOR CONVERTING AN ORGANIC REACTANT STREAM COMPRISNG, MAINTAINING A DOWNWARDLY MOVING BED OF HEAT RETENTIVE SOLID PARTICLES IN EACH OF A REACTION ZONE AND A SUPERIMPOSED HEATING ZONE, PASSING SAID ORGANIC REACTANT STREAM UPWARDLY AT CONVERSION TEMPERATURE THROUGH THE BED IN SAID REACTION ZONE, REMOVING A STREAM OF FLUID CONVERSION PRODUCTS FROM THE UPPER PORTION OF THE REACTION ZONE AND CONTINUOUSLY WITHDRAWING CONTACTED SOLID PARTICLES FROM THE LOWER PORTION THEREOF, COMMINGLING SOLID PARTICLES THUS WITHDRAWN WITH A GAS STREAM COMPRISING HOT COMBUSTION GASES OBTAINED AS HEREINAFTER SET FORTH, PASSING THE RESULTANT SUSPENSION UPWARDLY IN A CONFINED STRAIGHT LINE PATH EXTENDING THROUGH THE REACTION ZONE AND THE BED THEREIN AND THROUGH SUBSTANTIALLY THE HEIGHT OF THE BED IN SAID HEATING ZONE AND MAINTAINED IN HEAT EXCHANGE WITH BOTH OF SAID BEDS, DISCHARGING THE SOLID PARTICLES FROM SAID SUSPENSION ONTO THE TOP PORTION OF THE BED IN SAID HEATING ZONE, CONTINUOUSLY PASSING A FREE OXYGENCONTAINING GAS UPWARDLY THROUGH THE BED IN SAID HEATING ZONE AND BURNING CARBONACEOUS MATERIAL THEREIN, PASSING A STREAM OF THE RESULTANT HEATED SOLID PARTICES DOWNWARDLY FROM THE LOWER PORTION OF SAID HEATING ZONE AT A TEMPERATURE ABOVE SAID CONVERSION TEMPERATURE TO THE UPPER PORTION OF THE BED IN SAID REACTION ZONE, DISCHARGING HOT COMBUSTION GASES UPWARDLY FROM THE DESCENDING BED AND SAID CONFINED STRAIGHT LINE PATH IN THE UPPER PORTION OF SAID HEATING ZONE, AND THEREFROM SUPPLYING A STREAM OF SAID HOT COMBUSTION GASES AT SUBSTANTIALLY THEIR TEMPERATURE OF DISCHARGE FROM THE HEATING ZONE TO SAID WITHDRAWN CONTACTED APRTICLES ENTERING SAID CONFINED STRAIGHT LINE PATH.
