Apparatus for contacting gases with granular solids

Claim 1

APPRATUS FOR CONDUCTING A CHEMICAL REACTION COMPRISING IN COMBINATION, A REACTION VESSEL, A HEATER FOR SOLID GRANULAR MATERIAL, A COOLER FOR SOLID GRANULAR MATERIAL, AN UPPER HORIZONTAL PARTITION ACROSS SAID REACTION VESSEL SPACED BELOW THE UPPER END THEREOF, A SECOND HORIZONTAL PARTITION ACROSS SAID REACTION VESSEL SPACED SUBSTANTIALLY BELOW SAID FIRST PARTITION AND A SUBSTANTIAL DISTANCE ABOVER THE LOWER END OF SAID VESSEL, SAID PARTITIONS DIVIDING SAID REACTION VESSEL INTO THREE SUPERPOSED CHAMBERS, A CONFINED PASSAGE FOR SOLID MATERIAL TRANSFER COMMUNICATING SAID COOLER WITH THE CHAMBER ABOVE SAID UPPER PARTITION, A CONFINED PASSAGE FOR SOLID MATERIAL TRANSFER COMMUNICATING SAID HEATER WITH THE CHAMBER BETWEEN SAID PARTITIONS, A PLURALITY OF TUBES EXTENDING DOWN FROM SAID UPPER PARTITION TO A LEVEL IN SAID REACTION VESESL BELOW SAID SECOND PARTITION, A SECOND PLURALITY OF TUBES EXTENDING DOWNWARDLY FROM SAID SECOND PARTITION TO A LEVEL IN SAID VESSEL SPACED A SUBSTANTIAL DISTANCE BELOW THE LOWER ENDS OF SAID FIRST NAMED TUBES, FLUID DISTRIBUTORS IN SAID VESSEL A SUBSTANTIAL DISTANCE BELOW THE LOWER ENDS OF SAID SECOND NAMED TUBES, A GAS OUTLET FROM SAID VESSEL AT A LEVEL BELOW SAID LOWER PARTITION AND ABOVE THE LOWER ENDS OF SAID FIRST NAMED TUBES, AND AN OUTLET CONDUIT FOR SOLID MATERIAL CONNECTED TO THE LOWER END OF SAID REACTION VESSEL.
