Improvements in or relating to catalysts

摘要

A catalyst is made by intimately associating Al2O3 and/or SiO2-Al2O3 with one or more oxides of Group II metals, calcining at at least 900 DEG C. but below fusion temperature so as to cause interaction of the associated catalyst constituents, and depositing one or more metals or oxides of Group VIII thereon. Ca is specified from Group II and Ni from Group VIII.
