Abstract
A method for preparing an iron oxide containing dehydrogenative catalyst having improved moisture stability which comprises calcining by a two step method. The temperature of calcination is maintained at from about 250.degree. to about 600.degree. C. in the first step and from about 700.degree. to about 800.degree. C. in the second step. The effectiveness of the catalyst is not substantially changed from that of the single step calcination known to the art while the moisture stability is improved.
