  • Patent number: 4350609
    Abstract: This invention relates to a method for selectively removing molybdenum values from a spent catalyst and producing a fresh molybdenum-containing catalyst. Such a method preferably contacts anhydrous gaseous hydrogen chloride at an elevated temperature with the metal containing catalyst which is substantially free of carbonaceous material to selectively remove molybdenum therefrom, and producing a fresh molybdenum-containing catalyst by depositing molybdenum from the vapor phase onto a fresh support in the presence of air. At least 50 weight percent and generally as much as 95 weight percent of the molybdenum is removed while other metals such as iron, titanium, cobalt and nickel along with the supporting alumina or silica are not affected.
