(The ) Daily Question on Basic Knowledge of Ammonia Synthesis Production is taken from the intermediate-level test bank for ammonia synthesis operators. We encourage all participants to get involved actively. The purpose of this activity is to review the knowledge we have already learned, to improve and strengthen everyone’s fundamental theoretical knowledge through answering questions, so as to ensure that one remembers what has been learned and can recall it in case it has been forgotten. The top 50 answerers will definitely receive a reward. Please reply with the answer hidden; otherwise it will be invalid.
