2025-06-17 03:10 · According to data from the Tianyancha app, Sinopec (600028) has newly obtained an invention patent grant. The title of the patent is “A Sulfur-Resistant Shift Catalyst, Its Preparation Method, and Applications”; the patent application number is CN202111272138.3, and the grant date is June 17, 2025. Patent abstract: A sulfur-resistant shift catalyst and its preparation method are provided. The catalyst comprises a carrier, an active component, a first additive, and a second additive; the active component is uniformly dispersed within the structure of the carrier, which consists of basic polymeric composite metal oxides ； The active components include cobalt-containing compounds and molybdenum-containing compounds ； The first additive includes at least one element selected from the lanthanum series or the cerium series ； The second additive includes potassium. This catalyst features good structural stability and activity stability, making it suitable for conversion conditions involving low temperatures, high pressures, and high CO concentrations. It exhibits low loss of alkali metals and a long service life, thus offering good economic benefits and promising application prospects.
