Estimating the term…
An ammonia synthesis system for synthesizing ammonia includes a reactor accommodating a catalyst for promoting a synthesis reaction of ammonia from a reactant gas containing hydrogen and nitrogen and a controller that controls an H2/N2 ratio that is a ratio of hydrogen to nitrogen in the reactant gas introduced into the reactor. The controller controls the H2/N2 ratio during a pre-activation operation for raising a temperature of the catalyst to an activation temperature associated with activation of the catalyst, to be a value different from the H2/N2 ratio during a post-activation operation that is an operation after the temperature of the catalyst reaches the activation temperature.
