【Abstract】 During the catalyst reduction through temperature increase and the semi-load operation of the ammonia synthesizing system,the catalyst is poisoned by the long-term excessive CO and CO 2,which makes the activity of the catalyst degenerate permanently and the temperature difference of the same-levelled catalyst enlarge and the full load productio of the system be difficult.After the necessary measures being taken,the catalyst has been used for another two years and its use ratio still remains high.更多还原
