In practical use, ammonia (NH3) can be burned directly in internal combustion (IC), diesel or Stirling engines. However, because NH3 has such a low flame temperature and is hard to ignite, it has generally not been widely used in these applications. Because NH3 can be easily reformed into hydrogen (H2), and as part of the effort to examine the benefits of ammonia for terrestrial applications, we develop processes for catalytic reformation of NH3 and utilize microfibrous materials to encapsulate reforming catalyst. After demonstrating reformation of NH3 studies were conducted on the stability and feasibility of burning NH3 by itself and burning NH3 with synthetic reformate. Favorable conditions for flame stability of combustion of hydrogen reformed from ammonia through this catalyst-impregnated microfibrous porous media were obtained and the results are presented. Initial findings demonstrated stable catalytic combustion and flame temperatures of 940oC were obtained. |
