IN A HYDROCARBON CONVERSION PROCESS COMPRISING THE STEPS OF MAKING A MECHANICAL MIXTURE COMPRISING REACTIVE HYDROCARBON, AND AN IMMISCIBLE FLUID HYDROCARBON REACTING CATALYST, REACTING AND CONVERTING A PORTION OF SAID REACTIVE HYDROCARBON IN THE PRESENCE OF SAID MECHANICALLY MIXED CATALYST TO FORM A CONVERTED A PORTION OF BON AND CATALYST CONTAINING TOTAL EFFLUENT, THE SPECIFIC GRAVITY OF THE HYDROCARBON PORTION OF SAID TOTAL EFFLUENT BEING SUBSTANTIALLY DIFFERENT FROM THAT OF SAID FLUID CATALYST, SEPARATING THE HYDROCARBON PORTION OF SAID TOTAL EFFLUENT FROM SAID CATALYST, RECYCLING TO SAID CONVERSION SEPARATED HYDROCARBON PORTION OF SAID EFFLUENT TO SAID CONVERSION PROCESS AND RECYCLING TO SAID CONVERSION PROCESS THE MAJOR PORTION OF SAID SEPARATED CATALYST, THE IMPROVEMENT COMPRISING MEASURING THE SPECIFIC GRAVITY OF SAID TOTAL EFFLUENT, AND CONTROLLING THE RATIO OF CATALYST TO THE HYDROCARBON PORTION PRESENT IN SAID CONVERSION PROCESS BY CONTROLLING THE RELATIVE RATES OF SAID TWO RECYCLES TO TEND TO MAINTAIN SAID SPECIFIC GRAVITY OF SAID TOTAL EFFLUENT AT A PREDETERMINED DESIRED VALUE.
