Water-gas shift reaction (WGS CO conversion) High-temperature shift (HTS)

The water-gas shift (WGS) reaction, also known as CO conversion, is an important chemical process in industry. It converts carbon monoxide (CO) and water (H₂O) into carbon dioxide (CO₂) and hydrogen (H₂). This reaction plays a central role in hydrogen production and simultaneously helps to reduce the CO content in synthesis gas. The process consists of two main phases: the high-temperature shift (HTS) and the low-temperature shift (LTS). Each of these phases utilizes different temperature ranges and catalysts to achieve optimal results.

For hydrogen enrichment in synthesis gas through CO conversion (H₂O + CO → H₂ + CO₂), the HTS catalyst ShiftMax 120 HCF is used at high CO concentrations and higher inlet temperatures. This catalyst is employed in syngas conditioning to achieve optimal results.
