Claim 1
Independent Claim

A METHOD FOR PREPARING A SLURRY OF A SUPPORTED CATALYST WHICH COMPRISES THE STEPS OF: (1) SLURRYING A FINELY DIVIDED NON-POROUS PYROGENIC OXIDE OF AT LEAST ONE ELEMENT SELECTED FROM THE GROUP CONSISTING OF AL, ZR, TI, AND SI WITH AN AQUEOUS SOLUTION OF A CATALYTIC METAL PROMOTOR ELEMENT TO IMPREGNATE SAID PYROGENIC OXIDE WITH THE CATALYTIC ELEMENT, (2) MIXING THE SLURRY THUS FORMED WITH AN INERT, NONDELETERIOUS LIQUID HYDROCARBON IN AN AMOUNT SUFFICIENT TO FORM AN ADMIXTURE CONTAINING A MAJOR PROPORTION OF SAID HYDROCARBON, (3) MILLING THE MIXTURE OBTAINED IN STEP (2) AT A TEMPERATURE SUCH THAT REACTION BETWEEN THE HYDROCARBON IN SAID DISPERSION AND THE CATALYST IS MINIMIZED UNTIL A UNIFORM DISPERSION IS OBTAINED, (4) SUBJECTING THE DISPERSION OBTAINED IN STEP (3) TO FLASHING CONDITIONS TO FREE THE DISPERSION OF WATER, AND (5) RECOVERING A SLURRY OF CATALYST IN SAID HYDROCARBON SUBSTANTIALLY FREE OF WATER AS A PRODUCT AMENABLE TO BEING PASSED DIRECTLY TO A REACTION ZONE.
