Abstract
The present invention discloses an inventive method for manufacturing a catalyst using alloy granules having a high-Ni content. The inventive method may include providing alloy granules comprising aluminum and nickel, and treating the alloy granules with an alkaline solution to form the catalyst. A content of the nickel in the alloy granules may be within a range of about 43 wt % to about 60 wt %. The alloy granules may have effective diameters within a range of about 1 mm to about 10 mm. The catalyst may have an attrition value of less than about 7.0%.
Claims16
A catalyst formed by a method comprising providing alloy granules comprising aluminum and nickel, and treating the alloy granules with an alkaline solution comprising 1 wt % to 20 wt % sodium hydroxide to form the catalyst,
- wherein a content of the nickel in the alloy granules is 53 wt % to 60 wt %,
- wherein at least 40% of the aluminum from the alloy granules is leached upon treating with the alkaline solution,
- wherein the catalyst exhibits an attrition value of less than 5.0%, and
- wherein the catalyst comprises nickel and aluminum, and wherein a content of the nickel in the catalyst is about 57 wt % to about 75 wt %.
