Abstract:
The present invention relates to a method of preparing a catalyst for oxidative dehydrogenation. More particularly, the present invention provides a method of preparing a catalyst for oxidative dehydrogenation providing superior selectivity and yield for a conjugated diene according to oxidative dehydrogenation by constantly maintaining pH of a coprecipitation solution using a drip-type double precipitation method to adjust an α-iron oxide content in a catalyst in a predetermined range.

Claim (Index 14):
A catalyst for oxidative dehydrogenation, the catalyst comprising an AFe 2 O 4  structure; and an Fe 2 O 3  structure,\n wherein A is one or more selected from the group consisting of copper (Cu), radium (Ra), barium (Ba), strontium (Sr), calcium (Ca), beryllium (Be), zinc (Zn), magnesium (Mg), manganese (Mn), and cobalt (Co), and a content of the AFe 2 O 4  structure is 38 to 85% by weight, and a content of the Fe 2 O 3  structure is 15 to 62% by weight.
