Abstract:

The paper presents the possibilities of nickel, aluminum and magnesium separation from acid solutions that are obtained from spent steam-reforming catalysts treated with sulfuric acid. Flow sheets for obtaining electroplating nickel sulfate, aluminum sulfate (alum) and industrial magnesium chloride are established.

Keywords:

metal recovery, catalyst recycling, ion exchange, nickel, steam-reforming catalyst.
