Abstract
An iron oxide/molybdenum oxide catalyst, used in a process for oxidizing alcohols, is regenerated by treatment with a non-oxidizing compound of molybdenum in solution, drying and heating in an air stream. The catalyst may be regenerated in situ by adding a solution of ammonia or an amine, e.g. methylamine, which dissolves the free MoO3 and redistributes it over the catalyst body which may be supported e.g. on silicon carbide. Alternatively a solution of MoCl2 in alcohol may be used. After soaking for an hour with the warm solution, the catalyst is then treated with warm air and finally heated to 495 DEG F. The catalyst may also be removed and sieved to segregate the major part which passes a mesh of 4 per sq. inch, but is retained by 20 mesh. The fines passing 20 mesh, which contain the major part of free MoO3, are extracted with ammonia or an amine, and used to treat the segregated catalyst. Specifications 814,073 and 814,074 are referred to.
