Abstract
A selection of stainless steels and special alloys for the oxidation o f organic contaminations in aqueous solutions under high pressure and high temperatures (SCWO - Supercritical Water Oxidation) is shown. A h igh pressure laboratory plant for representative corrosion studies und er real conditions of SCWO (temperatures above 647.35 K, pressure abov e 22.1 MPa) is described. The corrosion behavior of the selected alloy s (X 2 CrNiMo 18 10; X 5 CrNiMo 17 12 2; X 5 CrNi 18 10; NiCr 15 Fe; N iMo 16 Cr 16 Ti; NiCr 23 Mo 16 Al) in operation as fittings and reacto r material is presented and discussed. Especially the degradation of 4 -chlorophenol with oxygen as oxidizing agent shows clearly the differe nce in corrosion resistance between stainless steels and nickel alloys .
