Reactor for vapor phase catalytic conversion

Claim 1

IN AN APPARATUS FOR CARRYING OUT VAPOR PHASE CATALYTIC CONVERSIONS COMPRISING A VERTICAL REACTOR SHELL HAVING FEED INLETS AND A PRODUCT OUTLET, UPPER AND LOWER BEDS OF INERT FINELY DIVIDED SOLID HEAT EXCHANGE PARTICLES, MEANS FOR DISCHARGING THE PARTICLES FROM THE UPPER BED AND THE LOWER BED IN A FALLING CONDITION, MEANS FOR RETURNING THE FALLEN PARTICLES IN THE LOWER BED TO THE UPPER BED, MEANS FOR ADJUSTING THE TEMPERATURE OF SAID FALLEN PARTICLES, AND A REACTION ZONE BETWEEN SAID UPPER AND LOWER BEDS, THE IMPROVEMENT WHICH COMPRISES A PLURALITY OF FIXED CATALYST BEDS HORIZONTALLY AND VERTICALLY SPACED APART IN SAID REACTION ZONE, AND BAFFLS WHICH COVER AND SUPPORT THE CATALYST BEDS AND DEFINE SUBSTANTIALLY VERTICAL ZIGZAG SHAPED CHANNELS BETWEEN SAID CATALYST BEDS THROUGH WHICH THE PARTICLES FALL FROM SAID UPPER BED TO SAID LOWER BED AND IMPINGE ON SAID BAFFLES WHILE FALLING THROUGH SAID CHANNELS, SAID CATALYST BEDS BEING PREVIOUS TO UPWARDLY FLOWING VAPORS WHICH ENTER AND LEAVE THROUGH APERTURES FORMED BY THE BAFFLES WHICH COVER AND SUPPORT THE CATALYST BEDS.
