Apparatus and process for high temperature conversions

Claim 1

A PROCESS FOR CONDUCTING HIGH TEMPERATURE REACTIONS AT VERY CONTACT TIMES OF CONTROLLED DURATION WHICH COMPRISES ESTABLISHING A REACTION ZONE SURROUNDED BY SAID COMMUNICATING AT ITS LOWER OPEN END WITH AN INTERMEDIATE POINT IN A QUENCHING ZONE, PASSING A PRIMARY STREAM OF HOT GRANULAR SOLIDS DOWNWARDLY BY GRAVITY AS A MOVING BED INDIRECTLY THROUGH SAID QUENCHING ZONE AND DIRECTLY INTO SAID REACTION ZONE AND THEN FROM ITS LOWER OPEN END DIRECTLY INTO SAID QUENCHING ZONE, PASSING A SECONDARY STREAM OFCOLD GRANULAR SOLIDS DOWNWARDLY BY GRAVITY AS A MOVING BED ENTIRELY AROUND SAID REACTION ZONE THROUGH SAID QUENCHING ZONE, PASSING SAID SOLIDS AS A MIXED WARM STREAM FROM THE BOTTOM THEREOF INTO A SOLIDS PRESSURE FEEDING ZONE, RAISING THE PRESSURE OF FLUIDS IN THE INTERSTICES OF SAID WARM SOLIDS THEREIN TO A PRESSURE SUBSTANTIALLY ABOVE THAT OF SAID REACTION AND QUENCHING ZONES, PASSING THE THUS PRESSURED SOLIDS THROUGH AN ELONGATED SOLIDS CONVEYANCE AND COOLING ZONE AS AN UPWARDLY MOVING BED CONCURRENTLY WITH A CONVEYANCE FLUID TO COOL THE SOLIDS AND HEAT THE FLUID, APPLYING A FORCE AGAINST A MASS OF SOLIDS DISCHARGING AT THE OUTLET OF SAID SOLIDS CONVEYANCE AND COOLING ZONE TO MAINTAIN SAID SOLIDS THEREIN AS A MOVING MASS HAVING SUBSTANTIALLY THE SOLIDS'' STATIC BULK DENSITY, PASSING A PRIMARY STREAM OF SAID SOLIDS DOWNWARDLY THROUGH A HEATING ZONE TO FORM SAID PRIMARY STREAM OF HOT SOLIDS,
