Alumina-, cerium oxide- and zirconium oxide-based compounds possessing high reducibility, the preparation procedure therefor and use in the preparation of catalysts

摘要

A cpd. comprising alumina, cerium and zirconium oxides, which shows a stabilised capacity for the absorption of hydrogen up to a temp. of at least 1000 degrees C. Also claimed is the method of prepn. of the prod., the precursor of the acid prod. and its use as a catalyst.
