Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
137 words
A METHOD OF EFFECTING AN EXOTHERMIC HYDROCRACKING REACTION AND AN ENDOTHERMIC REACTION IN A SINGLE REACTION ZONE COMPRISING INTRODUCING INTO SAID ZONE (1) A HYDROCRACKING CATALYST OF A SHAPE SELECTIVE CRYSTALLINE ALUMINOSILICATE ZEOLITE CHARACTERIZED BY PORES HAVING A SUBSTANTIALLY UNIFORM DIAMETER NOT EXCEEDING ABOUT 5 ANGSTROM UNITS, (2) A FLUID CHARGE COMPRISING HYDROGEN AND A COMPONENT CAPABLE OF ENTERING INTO THE PORES OF SAID CATALYST AND UNDERGOING AN EXOTHERMIC HYDROCRACKING REACTION, (3) A SOLID POROUS CATALYST FOR AN ENDOTHERMIC REACTION, AND (4) A FLUID CHARGE CAPABLE OF UNDERGOING AN ENDOTHERMIC RACTION BUT INCAPABLE OF ENTERING INTO THE PORES OF SAID HYDROCRACKING CATALYST, AND REGULATING THE PROPORTIONS OF THE FOREGOING CHARGES SUCH THAT THE HEAT EVOLVED FROM SAID EXOTHERMIC HYDROCRACKING REACTION SERVES TO MAINTAIN SAID REACTION ZONE AT A TEMPERATURE SUFFICIENT TO EFFECT AND SUSTAIN SAID ENDOTHERMIC REACTION.
