Abstract

A system 1 is disclosed which includes a compression unit for generating hydrogen gas from water and a reaction material, resulting in generation of a residue, and for lowering the pH of the residue. The compression unit includes a reaction chamber 2 which is adapted to employ a chemical process to generate the hydrogen gas from water in an exothermic reaction with the reaction material. The reaction chamber is connected to a neutralisation unit, which contains carbon dioxide and supplies the residue in the reaction chamber with carbon dioxide to neutralise an alkali material therein. A control unit is connected to the neutralisation unit to control a quantity of carbon dioxide supplied to the reaction chamber to lower the pH of the residue material. Also disclosed is a system for lowering the pH of bauxite processing residue (red mud) by addition of carbon dioxide and a method for lowering the pH of alkaline materials by addition of carbon dioxide.
