Method for conducting hightemperature conversions

Claim 1

THE METHOD FOR CONDUCTING ENDOTHERMIC CONVERSIONS OF GASEOUS HYDROCARBONS AT SUITABLE ELEVATED REACTION TEMPERATURES TO FORM GASEOUS HYDROCARBON PRODUCTS WHICH ARE UNSTABLE AT SAID REACTION TEMPERATURES WHICH COMPRISES: PASSING GASEOUS HYDROCARBON REACTANT THROUGH A PREHEATING ZONE TO HEAT IT TO A TEMPERATURE WITHIN ABOUT 300* F. BUT BELOW THE SUITABLE REACTION TEMPERATURE, PASSING THE PREHEATED REACTANT DIRECTLY TO AND THROUGH A CONFINED REACTION ZONE TO EFFECT CONVERSION THEREOF AT SAID SUITABLE REACTION TEMPERATURES, HEATING SAID REACTION ZONE ELECTRICALLY TO MAINTAIN ITS TEMPERATURE AND TO SUPPLY THE ENDOTHERMIC HEAT FOR THE REACTION, MIXING A SUITABLE LIQUID QUENCHING MEDIUM WITH THE GASEOUS REACTION PRODUCTS PASSING FROM SAID REACTION ZONE TO PARTIALLY QUENCH EHT PRODUCTS TO A TEMPERATURE BELOW THE REACTION TEMPERATURE BUT WITHIN ABOUT 300* F. THEREOF, PASSING THE PARTIALLY QUENCHED GASEOUS PRODUCTS THROUUGH A COOLER MOVING BED OF REFRACTIVE PARTICLE-FORM CONTACT MATERIAL IN A CONFINED QUENCH ZONE TO QUENCH SAID GASEOUS PRODUCTS TO A TEMPERATURE AT WHICH THE PRODUCTS ARE SUBSTANTIALLY STABLE, WITHDRAWING QUENCHED GASEOUS PRODUCTS FROM SAID QUENCH ZONE, PASSING A PARTICLE-FORM REFRACTIVE CONTACT MATERIAL THROUGH A PLURALITY OF ZONES IN SERIES THE FIRST OF WHICH IS SAID QUENCH ZONE WHEREIN IT MOVES AS A COMPACT BED COUNTERCURRENTLY TO SAID GASEOUS PRODUCTS TO BE HEATED TO A TEMPERATURE WITHIN ABOUT 300* F. OF BUT BELOW THE SUITABLE GASEOUS REACTANT CONVERSION TEMPERATURE, AND THE LAST OF WHICH IS SAID PREHEATING ZONE WHEREIN IT MOVES COUNTERCURRENTLY TO THE GASEOUS REACTANT CHARGE TO PREHEAT SAID CHARGE AND TO BE COOLED BY THE INCOMING GASEOUS REACTANT FROM A TEMPERATURE WITHIN ABOUT 300* F. OF SAID REACTION TEMPERATURES TO A TEMPERATURE APPROXIMATING THE DESIRED GASEOUS PRODUCT QUENCH TEMPERATURE, WITHDRAWING CONTACT MATERIAL FROM SAID PREHEATING ZONE AND PASSING IT TO SAID QUENCH ZONE AS THE CONTACT MATERIAL SUPPLY THERETO.

OF SAID REACTION TEMPERATURES TO A TEMPERATURE APPROXIMATING THE DESIRED GASEOUS PRODUCT QUENCH TEMPERATURE, WITHDRAWING CONTACT MATERIAL FROM SAID PREHEATING ZONE AND PASSING IT TO SAID QUENCH ZONE AS THE CONTACT MATERIAL SUPPLY THERETO.
