A METHOD FOR AUTOMATICALLY MEASURING HYDROCARBON CONVERSION IN THE RISER OF A FLUIDIZED CATALYTIC REACTOR AND CONTROLLING THE DEPTH OF CRACKING OF PETROLEUM OILS THEREBY IN A CATALYTIC CRACKING PROCESS RESPONSIVE TO A CONTROL SIGNAL CALCULATED BY A COMPUTER HAVING A FIXED PROGRAM, COMPRISING: MEASURING THE INDIVIDUAL RATES OF FLOW OF THE OIL AND STEAM FEEDS BEING INTRODUCED NTO A RISER OF A CATALYTIC REACTOR; PRODUCING A SIGNAL PROPORTIONAL TO THE TOTAL FEED MATERIAL FLOW RATE THROUGH SAID RISER; MEASURING THE TEMPERATURE OF SAID FEED MATERIALS IN THE LOWER PORTION OF SAID RISER; DETERMINING BY DIFFERENCE IN FLOW RATES OF THE TOTAL STREAM AND THE OIL AND STREAM FEEDS THE FLOW RATE OF REGENERATED CATALYST THROUGH SAID RISER; MEASURING THE TEMPERATURE OF SAID MATERIALS IN THE UPPER PORTION OF SAID RISER; PRODUCING A SIGNAL PROPORTIONAL TO SIGNALS THE TOTAL HEAT CONTENTS OF SAID FEED MATERIALS IN BOTH THE LOWER AND UPPER PORTIONS OF SAID RISER; PRODUCING A SIGNAL PROPORTIONAL TO THE HEAT ABSORBED BY THE REACTION OF SAID FEED MATERIALS, PRODUCING A SIGNAL PROPORTIONAL TO THE HYDROCARBON CONVERSION IN SAID RISER TO GIVE A FIRST SIGNAL; COMPARING SAID FIRST SIGNAL TO A CONSTANT SECOND SIGNAL, REPRESENTATIVE OF DESIRED HYDROCARBON CONVERSION TO OBTAIN A CONTROL SIGNAL, THE MAGNITUDE OF WHICH IS RELATED TO THE DIFFERENCE BETWEEN SAID FIRST AND SECOND SIGNALS; AND ADJUSTING THE FLOW RATE OF THE REGENERATION AIR TO SAID REGNERATOR RESPONSIVE TO SAID FIRST CONTROL SIGNAL UNTIL HYDROCARBON CONVERSION IN SAID RISER ATTAINS A DESIRED LEVEL.
