Method for the utilization of highly active hydrocarbon conversion catalysts

Claim 1

A METHOD FOR THE CONVERSION OF HYDROCARBONS COMPRISING CONTACTING THE HYDROCARBON WITH A MIXTURE OF AT LEAST TWO DIFFERENT TYPES OF DISCRETE SOLID PARTICLES, SOLID APRTICLES OF A FIRST TYPE BEING SUBSTANTIALLY COMPOSED OF CATALYSTIC MATERIAL POSSESSED OF AN ACTIVITY FOR CRACKING GAS OIL WHICH IS AT LEAST ABOUT TWICE AS GREAT AS THAT OF CONVENTIONAL AMORPHOUS SILICA ALUMINA CRACKING CATALYST, AND SOLID MATERIALS OF OTHER TYPE BEING MATERIALS HAVING CATALYTIC ACTIVITY SUBSTANTIALLY BELOW THAT OF THE FIRST TYPE, BUT HAVING ABOUT THE SAME DENSITY, SOLID MATERIALS OF OTHER TYPE BEING PRESENT IN AN AMOUNT SUCH THAT THE TOTAL SOLIDS ENTERING THE REACTOR FROM THE REGENERATOR ARE SUFFICIENT TO SUPPLY THE REACTOR HEAT DEMAND ABOVE THE HEAT SUPPLY OF THE INCOMING FLUID REACTANTS, THE CONDITIONS OF TEMPERATURE, SPACE VELOCITY, AND TIME OF EXPOSURE OF SOLIDS TO HYDROCARBONS BEING SUCH AS TO EFFECT SUBSTANTIAL CONVERSION BY PARTICLES OF THE FIRST TYPE WHILE EFFECTING LESS CONVERSION BY PARTICLES OF OTHER TYPE, SUCH CONDITIONS BEING: TEMPERATURE BETWEEN ABOUT 750* AND ABOUT 1000*F. WEIGHT SAPCE VELOCITY OF HYDROCARBON WITH RESPECT TO PARTICLES OF THE FIRST TYPE FROM ABOUT 200 TO ABOUT 700 RESIDENCE TIME OF SOLIDS WITHIN THE REACTION AREA FROM ABOUT 2 TO ABOUT 60 SECONDS, AND RESISDENCE TIME OF HYDROCARBONS AND OF SOLIDS WITHIN THE REACTION AREA BEING OF ABOUT THE SAME VALUE; REGENERATING THE MIXED SOLIDS AFTER REACTION, AND RETURNING THE REGENERATED SOLIDS TO REACTION.

Claim 2

A METHOD FOR THE CONVERSION OF HYDROCARBONS COMPRISING CONTACTING THE HYDROCARBON WITH A MIXTURE OF AT LEAST TWO DIFFERENT TYPES OF DISCRETE SOLID PARTICLES, SOLID APRTICLES OF A FIRST TYPE BEING SUBSTANTIALLY COMPOSED OF CATALYSTIC MATERIAL POSSESSED OF AN ACTIVITY FOR CRACKING GAS OIL WHICH IS AT LEAST ABOUT TWICE AS GREAT AS THAT OF CONVENTIONAL AMORPHOUS SILICA ALUMINA CRACKING CATALYST, AND SOLID MATERIALS OF OTHER TYPE BEING MATERIALS HAVING CATALYTIC ACTIVITY SUBSTANTIALLY BELOW THAT OF THE FIRST TYPE, BUT HAVING ABOUT THE SAME DENSITY, SOLID MATERIALS OF OTHER TYPE BEING PRESENT IN AN AMOUNT SUCH THAT THE TOTAL SOLIDS ENTERING THE REACTOR FROM THE REGENERATOR ARE SUFFICIENT TO SUPPLY THE REACTOR HEAT DEMAND ABOVE THE HEAT SUPPLY OF THE INCOMING FLUID REACTANTS, THE CONDITIONS OF TEMPERATURE, SPACE VELOCITY, AND TIME OF EXPOSURE OF SOLIDS TO HYDROCARBONS BEING SUCH AS TO EFFECT SUBSTANTIAL CONVERSION BY PARTICLES OF THE FIRST TYPE WHILE EFFECTING LESS CONVERSION BY PARTICLES OF OTHER TYPE, SUCH CONDITIONS BEING: TEMPERATURE BETWEEN ABOUT 750* AND ABOUT 1000*F. WEIGHT SAPCE VELOCITY OF HYDROCARBON WITH RESPECT TO PARTICLES OF THE FIRST TYPE FROM ABOUT 200 TO ABOUT 700 RESIDENCE TIME OF SOLIDS WITHIN THE REACTION AREA FROM ABOUT 2 TO ABOUT 60 SECONDS, AND RESISDENCE TIME OF HYDROCARBONS AND OF SOLIDS WITHIN THE REACTION AREA BEING OF ABOUT THE SAME VALUE; REGENERATING THE MIXED SOLIDS AFTER REACTION, AND RETURNING THE REGENERATED SOLIDS TO REACTION.
