Inert material CS 222 Al2O3-SiO2 spheres
CS 222 inert material consists of Al₂O₃-SiO₂ spheres, available in various sizes, which can be used, for example, as a bottom layer in a fixed-bed

In feed gas production for ammonia synthesis, hydrogen enrichment of the synthesis gas is achieved through the water gas shift (WGS) reaction
CO + H₂O → CO₂ + H₂.
After the secondary reformer, a high-temperature shift (HTS) catalyst is first applied, followed by a low-temperature shift (LTS) catalyst such as ShiftMax 210 to further increase the H₂ yield.
The use of ShiftMax 210 enables maximum conversion of residual CO at lower temperatures, which is essential because CO acts as a catalyst poison for ammonia synthesis. By minimizing the CO concentration in the N₂-containing synthesis gas, downstream methanation can completely remove the remaining traces of CO, ensuring optimal feed gas quality for the Haber–Bosch process.
In addition to ammonia synthesis, the LTS catalyst ShiftMax 210 can also be applied in hydrogen production schemes where pressure swing adsorption (PSA) is not available after the HTS stage. In such cases, the combination of HTS and LTS catalysts provides effective synthesis gas conditioning and high hydrogen purity.
