Abstract

Pt catalysts (0.2-2.5 wt.%) supported on coprecipitated 1.6 wt.% SnZnAl₂O₄ were prepared. SnZnAl₂O₄ spinel had the same lattice parameter as ZnAl₂O₄ independently of Pt impregnation. The highest platinum dispersion was obtained with a 0.5 wt.% platinum content. Catalytic activity for isobutane dehydrogenation and n-heptane conversion was more sensitive to chemical composition than to platinum dispersion.
