Abstract
This invention relates to improvements in a process for the preparation of a magnetic catalyst, particularly a magnetic reforming catalyst. In such process, a Group VIII noble metal is incorporated within an inorganic oxide particulate mass, suitably by impregnation of preformed particles. The metal-containing inorganic oxide particulate mass, in the desired proportion, is then admixed with magnetic alloy particles, notably iron or cobalt, and an inorganic oxide precursor which serves as a binder, to form a particulate composite mass comprised of particles of magnetic alloy dispersed as inclusions within an inorganic oxide matrix.
