Process of applying promoters to catalyst particles

Claim 1

THE PROCESS OF MAKING A FINELY DIVIDED IRON CATALYST CONTAINING AN AVERAGE CONCENTRATION OF PROMOTER SELECTED FROM THE CLASS CONSISTING OF ALKALI AND ALKALINE EARTH METAL COMPOUNDS OF BETWEEN ABOUT .1 AND ABOUT 2.5%, WHICH COMPRISES THE STEPS OF CLASSIFYING THE FINELY DIVIDED IRON CATALYST INTO RELATIVELY FINE AND RELATIVELY COARSE PARTICLES, APPLYING A RELATIVELY DILUTE SOLUTION OF PROMOTOR TO THE SURFACE OF THE RELATIVELY FINE CATAYST PARTICLES, APPLYING A RELATIVELY STRONG SOLUTION OF PROMOTOR TO THE SURFACE OF THE RELATIVELY COARSE CATALYST PARTICLES, THE CONCENTRATION OF SOLUTION OF PROMOTOR BEING CORRELATED WITH THE WEIGHT OF THE IRON PARTICLES IN A DIRECT PROPORTION RELATIONSHIP, SEPARATELY DRYING THE TWO SIZES OF PROMOTED CATALYST, AND RECOMBINING TO PRODUCE A FLUIDIZABLE MIXTURE OF FINELY DIVIDED IRON CATALYST HAVING A UNIFORM PROPORTION OF PROMOTOR IN EACH SIZE RANGE BASED UPON THE WEIGHT OF CATALYST.
