摘要：
Iron ore containing higher concentration of phosphorus is reduced by hydrogen gas containing water vapor. 13% of removing yield of phosphorus is obtained. It is observed that removing rate of phosphorus can be expressed as apparent 1st order reaction equation. The reaction rate equation is divided into two parts. Rate constant of the former reaction is about 10 time larger than that of the latter equation. It is estimated on the basis of a previous research result that phosphorus removed from iron oxide is gaseous phosphorus and form of remained phosphorus is Fe2P.
