Outline of Final Research Achievements

The catalytic performance in oxidative dehydrogenation of propane was investigated for trace-metal-containing hydroxyapatites, which were obtained with different thermal treatment operations, for utilization of unused P resource such as excess sludge. In the simulated acid-extracted liquid containing P and small amount of Fe from carbonated sludge, the preparation of HAp involved attraction of all Fe ions, leading to the catalytic activity nearly the same as that of HAp containing similar amount of Fe forming under the basic conditions.
The catalytic activity was affected by catalyst preparation scheme, Fe content, thermal treatment operation and its temperature. Comparison of the catalytic reaction tests at 550 degree C revealed that the optimum Fe contents favorable for high catalytic performance lie in the range of 0.5 to 1.5%, corresponding to the amount of Fe considered in the case of using excess sludge. The maximum propylene yield of 4.7% was demonstrated in this study.
