Abstract Scope |
Presented here is a novel aluminum fuel that can be derived directly from scrap feed stock. Typically, bulk aluminum has an oxide layer that prevents it from reacting with water at practical temperatures; however, our research has shown that by shredding and compacting a wide variety of aluminum stock and applying a minimal surface treatment of gallium and indium can disrupt the oxide layer at the grain boundaries, allowing the exothermic reaction to proceed to >99% completion, producing clean hydrogen gas and valuable boehmite in the process. Our experiments also show the robustness of this process to the presence of paint and other contaminants. Given that global recycling rates have been reduced recently by numerous factors, including complications with sorting waste by alloy content and lack of economic incentive, this approach provides another avenue for managing this waste stream, generating considerable value in the process. |
