| Abstract: | The reduction performances of both unreduced ZA-5 and pre-reduced ZA-5H ammonia catalyst with large particle size as used in industry were measured by thermogravimetry (NET-ZSCH STA 449C) . The effect of the temperature, pressure, space velocity, particle size and gas composition during reduction on the reduction rate and catalyst activity after reduction were investigated . The reduction particle size effect of catalyst ZA-5 and the basic principle of optimizing conditions for its industrial reduction were also proposed. The results are the references for guiding industrial reduction of ZA-5 and its optimization. |
| Keywords: | ammonia synthesis catalyst ZA-5 industrial grade particle size reduction performance |
