本文对郑州大学催化剂组研制并由郑州大学化工试验厂生产的A_6C和HAC型球形氨合成催化剂的诸密度进行了测定,并计算了比孔容、孔隙率和空隙率等,由于这种新型氨合成催化剂已在全国数十个中型及小型化肥厂使用,证明其确实具有节约能源,提高合成塔生产能力的优点,因而对物理化学性能的测定就显得迫切需要。 In this paper, the density of A_6C and HAC spherical ammonia synthesis catalysts developed by the catalyst group of Zhengzhou University and produced by Zhengzhou Chemical Experiment Factory were measured, and the specific pore volume, porosity and void ratio were calculated. Since this new ammonia Synthetic catalysts have been used in dozens of medium- and small-scale fertilizer plants in the country, proving that they do have the advantages of saving energy and improving the production capacity of the synthesis tower. Therefore, the determination of physicochemical properties is urgently needed.
