| Abstract: | The Cu, Cr, Al, Ni and Ti in corrosion solution of oxidation equipment in supercritical water by inductively coupled plasma-atomic emission spectrometry has been investigated, the authors used catalysts (CuO/Al2O3) to oxidize unsymmetrical dimetylhydrazine in supercritical water in a stainless steel (1Cr18Ni9Ti) reactor. The test was operated under condition of 400-500 degrees C and 24-26 MPa. The results indicate that the dissolution of Cr in stainless steel were occurred in supercritical water and dissolution became severe with higher temperature and pressure. |
