Inert spheres for gas distribution and temperature protection
CS 346 inert material consists of pure Al2O3 spheres, available in various sizes. They are used, for example, as a lower layer in a catalyst
The water gas shift (WGS) reaction is used to enrich hydrogen (H₂) in synthesis gas, which mainly consists of carbon monoxide (CO) and hydrogen. At relatively low inlet temperatures of approximately 200 °C resulting from upstream gas purification, the WGS reaction
CO + H₂O → CO₂ + H₂
is carried out over a medium-temperature shift (MTS) catalyst such as ShiftMax 300.
ShiftMax 300 is a Cu–Zn-based MTS catalyst specifically designed for applications with elevated CO concentrations and higher reaction exothermicity. In such cases, the heat released during the WGS reaction may exceed the thermal stability limits of low-temperature shift (LTS) catalysts such as ShiftMax 210. The use of an MTS catalyst allows stable operation without the need for additional excess steam to control reactor temperature, ensuring efficient hydrogen enrichment and reliable process performance.
