Method of producing hydrogen and carbon black

Claim 1

THE METHOD OF CRACKING GASEOUS HYDROCARBONS TO FORM HYDROGEN AND CARBON BLACK WHICH COMPRISES INTRODUCING THE GASES TO BE CRACKED WHILE IN PREHEATED CONDITION INTO THE LOWER INTERMEDIATE PORTION OF A REACTION VESSEL, INTRODUCING HOT SOLID PARTICLES WHILE AT A TEMPERATURE MATERIALLY ABOVE THE CRACKING TEMPERATURE OF SAID GAS INTO THE UPPER PORTION OF AID REACTION VESSEL, SHOWERING SAID SOLID PARTICLES DOWNWARDLY THROUGH SAID REACTION VESSEL AGANIST A RISING CURRENT OF SAID GASES WHEREBY THE GAS IS HEATED TO CRACKING TEMPERATURE BY CONTACT WITH FREE FALLING SOLIDS PARTICLES, WITHDRAWING SOLID PARTICLES FROM THE BOTTOM OF SAID REACTIO VESSEL AT A RATE SUFFICIENT TO PREVENT THE ACCUMULATION OF SOLID PARTICLES ABOVE THE POINT OF INTRODUCTION OF THE GASES IN SAID VESSEL, HEATING A PORTION OF THE SOLIDS SO WITHDRAWN TO A TEMPERATURE METERIALLY ABOVE THE CRACKING TEMPERATURE OF SAID GASES AND RETURNING THEM TO THE TOP OF SAID VESSEL AS AFORESAID, WITHDRAWING HOT CRACKED PRODUCTS COMPRISING CARBON BLACK AND HYDROGEN FROM THE UPPER PORTION OF SAID REACTION VESSEL, PASSING A PORTION OF THE SOLIDS WITHDRAWN FROM THE VESSEL COUNTERCURRENTLY TO THE INCOMING FEED GAS TO PREHEAT THE FEED GAS AND COOL THE SAID SOLIDS, MIXING THE COOLED SOLIDS WITH THE HOT CRACKED PRODUCTS, SEPARATING THE PRODUCT HYDROGEN FROM THE CARBON BLACK AND SOLIDS AND RECYCLING THE SOLIDS TO THE TOP OF THE REACTOR VESSEL.

Claim 2

THE METHOD OF CRACKING GASEOUS HYDROCARBONS TO FORM HYDROGEN AND CARBON BLACK WHICH COMPRISES INTRODUCING THE GASES TO BE CRACKED WHILE IN PREHEATED CONDITION INTO THE LOWER INTERMEDIATE PORTION OF A REACTION VESSEL, INTRODUCING HOT SOLID PARTICLES WHILE AT A TEMPERATURE MATERIALLY ABOVE THE CRACKING TEMPERATURE OF SAID GAS INTO THE UPPER PORTION OF AID REACTION VESSEL, SHOWERING SAID SOLID PARTICLES DOWNWARDLY THROUGH SAID REACTION VESSEL AGANIST A RISING CURRENT OF SAID GASES WHEREBY THE GAS IS HEATED TO CRACKING TEMPERATURE BY CONTACT WITH FREE FALLING SOLIDS PARTICLES, WITHDRAWING SOLID PARTICLES FROM THE BOTTOM OF SAID REACTIO VESSEL AT A RATE SUFFICIENT TO PREVENT THE ACCUMULATION OF SOLID PARTICLES ABOVE THE POINT OF INTRODUCTION OF THE GASES IN SAID VESSEL, HEATING A PORTION OF THE SOLIDS SO WITHDRAWN TO A TEMPERATURE METERIALLY ABOVE THE CRACKING TEMPERATURE OF SAID GASES AND RETURNING THEM TO THE TOP OF SAID VESSEL AS AFORESAID, WITHDRAWING HOT CRACKED PRODUCTS COMPRISING CARBON BLACK AND HYDROGEN FROM THE UPPER PORTION OF SAID REACTION VESSEL, PASSING A PORTION OF THE SOLIDS WITHDRAWN FROM THE VESSEL COUNTERCURRENTLY TO THE INCOMING FEED GAS TO PREHEAT THE FEED GAS AND COOL THE SAID SOLIDS, MIXING THE COOLED SOLIDS WITH THE HOT CRACKED PRODUCTS, SEPARATING THE PRODUCT HYDROGEN FROM THE CARBON BLACK AND SOLIDS AND RECYCLING THE SOLIDS TO THE TOP OF THE REACTOR VESSEL.
