Optimization of Catalytic Microreactors for Ammonia DecompositionPublic

Hydrogen is an attractive source for zero-emission energy because of its usefulness in fuel cell batteries. However, traditional methods to capture hydrogen for use in these cells, such as steam reforming, produce unwanted byproducts. Ammonia decomposition is a promising method to produce hydrogen, and our research explored the possibility of using catalyst-coated microreactors to improve the decomposition reaction. Microreactors have unique benefits over traditional reactors such as mass/heat transport properties, precision controls, and improved safety. Creation and characterization of thin films led to a design for a wall-coated nickel alumina catalyst microreactor. Our design was confirmed by testing various parameters of the microreactor by modeling heat transfer properties.
