A PROCESS OF HYDROGENATING FAT WITH A PARTICULATE NICKEL CATALYST INSLUDING THE STEPS OF INTRODUCING AN AMOUNT OF LIQUID FAT AND CATALYST INTO A HYDROGENATION ZONE, HYDROGENATING SAID FAT, REMOVING THE HYDROGENATED FAT AND CATALYST FROM SAID ZONE AND WHILE AT A TEMPERATURE ZONE AT A PREDETERMINED RATE OF FLOW IN WHICH ZONE TION ZONE AT A PREDETERMINED RATE OF FLOW IN WHICH ZONE ARE A PLURALITY OF CLOSELY SPACED MAGNETIC POLES TO REMOVER AT LEAST THE MAJOR PORTION OF SAID CATALYST FROM SAID FAT, DEMAGNETIZING SAID POLES AFTER SAID HYDROGENATED FAT HAS PASSED SAID SEPARATION ZONE, PASSING A SECOND AMOUNT OF UNHYDROGENATED FAT THROUGH SAID SEPARATION ZONE AT A SUBSTANTIALLY GREATER RATE OF FLOW THAN SAID PREDETERMONED RATE TO PICK UP THE CATALYST THEREIN, AND INTRODUCING SAID SECOND AMOUNT OF FAT AND THE PICKED UP CATALYST INTO A HYDROGENATION ZONE, ALL OF SAID PROCESSING BEING CARRIED ON IN THE SUBSTANTIAL ABSENCE OF AIR.

APPARATUS FOR USE IN THE HYDROGENAATION OF FAT WITH A PARTICULATE CATALYST HAVING MAGNETIC PROPERTIES INCLUDING A HYDROGENATION VESSEL HAVING MEANS TO INTRODUCE AND HYDROGENATE FAT THEREIN WITH SAID CATALYST, CONDUIT MEANS CONNECTED TO SAID VESSEL FOR REMOVING THE HYDROGENATED FAT AND CATALYST FROM SAID VESSEL, AND A MAGNETIC SEPARATOR IN SAID CONDUIT MEANS, SAID SEPARATOR COMPRISING A VESSEL PROVIDED WITH AN INLET AND AN OUTLET TO PERMIT THE FLOW OF THE LIQUID THROUGH THE INTERIOR OF THE VESSEL, A PLURAILITY OF CLOSELY WOVEN MASSES OF MAGNETIZABLE STRANDS DISPOSED WITHIN THE INTERIOR IN THE PATH OF FLOW OF THE LIQUID, SEVERAL MAGNETIZABLE GRIBS SEPARATING SAID WOVEN MASSES, AND A SOURCE OF MAGNETIC FLUX DISPOSED TO PLACE THE PLURALITY OF THE WOVEN MASSES AND THE SEVERAL MAGNETIZABLE GRIDS IN THE MAGNETIC CIRCUIT OF THE SOURCE.
