    摘要: A method for synthesizing ammonia for agricultural fertilizers employs water (H2O) as the source of hydrogen (H2) in ammonia (NH3) synthesis, and gathers carbon monoxide (CO) as a limiting reagent for combining in a WGS (Water-Gas-Shift) reaction for producing hydrogen. The WGS reaction employs CO with the water to produce Carbon Dioxide (CO2) and H2, consuming undesirable CO from other industrial applications. A by-product of the process includes generating 1.5 mole of CO2 for each mole of ammonia synthesized. An intermediate step consumes 3 moles of hydrogen for each mole of Nitrogen (N2). The use of methane gas is avoided as the process employs CO and the WGS reaction as an exclusive source of H2 without introducing methane (CH4). A downstream synthesis of ammonia can be done through a fuel cell to produce electricity for the ammonia synthesis for further sustainability.
