Method of catalyst control in organic reactions

Claim 1

THE IMPROVED METHOD OF EFFECTING CATALYZED EXOTHERMIC ORGANIC CONVERSIONS WHICH COMPRISES PASSING A FLUID REACITON MIXTURE TO BE CONVERTED THROUGH A REACTION ZONE AT CONDITIONS EFFECTIVE TO OBTAIN SAID CONVERSION AND SO CHOSEN THAT THE TEMPERATURE IS CAUSED TO INCREASE IN THE DIRECTION OF FLOW OF THE REACTION MIXTURE DUE TO THE EXOTHERMIC HEAT OF REACTION, INTRODUCING A SOLID MOBILE CATALYST FOR THE REACTION INTO SAID REACTION ZONE AT A PLURALITY OF POINTS SPACED IN THE DIRECTION OF FLOW, PASSING THE THUS-INTRODUCED CATALYST THROUGH SAID REACTION ZONE COUNTERCURRENTLY TO THE REACTION MIXTURE, AND SEPARATELY CONTROLLING THE QUANTITY AND ACTIVITY OF CATALYST INTRODUCED AT EACH SAID POINT TO PROVIDE A DECREASING AMOUNT OF CATALYST ACTIVITY IN THE DIRECTION OF FLOW OF REACTANTS AS AN INVERSE FUNCTION OF THE TEMPERATURE THUS TENDING TO EQUALIZE THE EXTENT OF REACTION THROUGHOUT SAID REACTION ZONE.
