High temperature shift
WebFeb 15, 2001 · The state of the copper promoter (0.17–1.5 wt%) was studied in Fe–Cr-based high-temperature shift (HTS) catalysts by in situ fluorescence XAFS combined with on-line gas analysis. The XANES spectra acquired in the fluorescence mode showed that Cu is present as copper metal under working conditions of the high temperature shift catalyst … WebThe HTS is a Fe-Cu-Cr catalyst that is relatively insensitive to poisons. HTS catalysts have lower activity and must be operated at higher temperatures (typically 350-470°C) the gas stream leaving the HTS reactor therefore contains …
