    Abstract: PROBLEM TO BE SOLVED: To obtain a catalytic for the dehydrogenation of n-paraffins excellent in the stability of catalytic activity by using an alkaline earth metal as an additional modifier to be supported on an inorganic carrier. SOLUTION: At least 0.01-5 wt.% of a platinum group metal, at least 0.01-5 wt.% of elemental tin, germanium, or lead as a promoter, and at least one metal modifier are supported on an inorganic carrier. The metal modifier is at least one alkaline earth metal of 0.01-20 wt.% based on a finished catalyst. The catalytic stability can be improved by using the alkaline earth metal modifier. Magnesium is used advantageously as the alkaline earth metal, and the dehydrogenation of 6-15C paraffins can be implemented by using the catalyst.
