The production of alloy granules and their use in hydrogen generation

摘要

Alloy granules are made by forming a first electrode 20 from metal sheets 12-14 of different compositions and powder 15 lying between the sheets (see Fig. 6). An arc is struck between the first electrode 20 and a second carbon electrode 19, thereby forming molten granules from the first electrode 20 which are collected in a revolving receptacle 17. The granules are made from aluminium, tin and zinc with trace amounts of silicon and antimony and are used in the generation of hydrogen. For hydrogen generation, granules (6, Fig 1) are placed in a reaction vessel (1, Fig 1) along with water (11, Fig. 1). Heat is then applied to the vessel, e.g. from electric elements or from a geothermal or solar source, and the evolved hydrogen gas is collected.
