Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
129 words
A METHOD OF CARRYING OUT ENDOTHERMIC HYDROCARBON CONVERSION REACTIONS WHICH COMPRISES CONTACTING VAPOROUS REACTANTS WITH A MIXTURE OF A MAJOR PROPORTION OF FINELY DIVIDED SOLID CATALYST PARTICLES AND A MINOR PROPORTION OF INERT, HEAT-TRANSFER SOLID PARTICLES OF GREATER DENSITY AND LARGER AVERAGE PARTICLE SIZE THAN SAID CATALYST PARTICLES IN A MAIN REACTION ZONE, CONTROLLING THE VAPOR VELOCITIES THROUGH SAID MIXTURES IN ORDER TO FORM A DENSE FLUIDIZED BED OF CATALYST PARTICLES IN SAID MAIN REACTION ZONE WITHOUT SUBSTANTIALLY INTERFERING WITH THE PASSAGE OF THE INERT HEAT TRANSFER SOLID PARTICLES DOWNWARDLY THROUGH THE FLUIDIZED BED, DISCHARGING A MIXTURE OF INERT HEAT TRANSFER SOLIDS AND CATALYST FROM THE BOTTOM OF SAID DENSE FLUIDIZED BED INTO A SETTLING ZONE OF SMALLER CROSS SECTIONAL AREA THAN AND ARRANGED DIRECTLY BENEATH SAID MAIN REACTION
