Compounds based on alumina, cerium oxide and zirconium oxide with high reducibility, process for their preparation and their 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.
