Method for manufacturing catalysts with reduced attrition

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%.
