Abstract (en)
[origin: CN107406252A] A chromium-free water-gas shift catalyst. In contrast to industry standard water-gas catalysts including chromium, a chromium-free water-gas shift catalyst is prepared using iron, boron, copper, aluminum and mixtures thereof. The improved catalyst provides enhanced thermal stability and avoidance of potentially dangerous chromium. Various embodiment's of a chromium-free water-gas catalyst including iron and boron are disclosed, some of which include copper, or aluminum and copper. The boron may reside substantially at the surface of the catalyst. In another series of embodiment's, a chromium-free water-gas catalyst may include boron and copper, and these embodiment's may further include aluminum or iron.
