Abstract
The very first results of isobutane dehydrogenation over metal-support ed mixed metallophosphate oxynitrides (AlMPON)-P-III (M-III = Ga, Cr) are presented. Catalytic tests show that the substitution of oxygen by nitrogen in the anionic network involves the appearance of new and mo re active sites. The substitution of a part of aluminium by gallium in oxynitride compounds increases significantly the activity while chrom ium does not modify to a great extent the conversion of isobutane.
