Fixed bed, pyrolytic, hydrocarbon conversion process employing a granular, heat-transfer medium

Claim 1

A FIXED BED, REGENERATIVE, REFRACTORY, PYROLYTIC METHOD FOR THE HIGH TEMPERATURE CONVERSION OF A GASIFORM HYDROCARBON REACTANT AT A TEMPERATURE ABOUT 1000*4000*F., WHICH COMPRISES PASSING A GASEOUS HEAT CARRIER THROUGH A FIXED BED, HEATING ZONE IN DIRECT HEAT EXCHANGE WITH A FIRST, STATIONARY AGGREGATE MASS OF REFRACTORY, HEAT-TRANSFER PARTICLES PREHEATED TO AN ELEVANTED TEMPERATURE CONDUCTIVE TO THE CONVERSION OF SAID REACTANT, THE CONFIGURATION OF SAID MASS AND NOMINAL DIAMETER OF SAID PRACTICLES BEING SUFFICIENT TO PROVIDE MINIMUM RESISTANCE TO THE FLOW OF SAID HEAT-CARRIER THROUGH SAID HEATING ZONE, PASSING THE HEATED, HEAT-CARRIER TO A VENTURI-TYPE MIXING AND REACTION ZONE IMMEDIATELY ADJACENT SAID HEATING ZONE, INTRODUCING A GASIFORM REACTANT INTO SAID MIXING AND REACTION ZONE AT THE VENTURI THROAT THEREOF, INTIMATELY CONTACTING SAID HEAT-CARRIER AND SAID REACTANT FROM ABOUT 0.00011 SECOND AT A REACTION TEMPERATURE OF ABOUT 1000*4000*F. AND A SUBATMOSPHERIC PRESSURE WITHIN SAID MIXING AND REACTION ZONE TO EFFECT THE CONVERSION OF SAID
