超易还原低温低压高活性氨合成催化剂

Studies of an Ultra-Easy-Reduction,High Activity,Low Temperatlire and Pressnre Ammonia Synthetic Catalyst

在氨合成催化剂活性评价高压装置和热重分析仪上系统地研究了新型氨合成催化剂ＺＡ－５的活性、耐热性能、抗含氧化合物的能力及其还原性能，并和ＩＣ１７４－１型、Ａ１１００－２型氨合成催化剂的性能进行了全面比较。试验结果表明，ＺＡ－５型催化剂是目前最佳的一种低温低压、高活性、极易还原并具良好稳定性的工业氨合成催化剂。

Tke activity,heat resistance, antipoisoning ability and reduction performance of a newammonia synthetic catalyst ZA-5 have been studied systematically with a high pressure catalytsevaluation instrument and a thermogravimetric analyzer.Comparative experiment results withICl74-1 and A110-2 catalysts demonstrate that ZA-5 catalvst has the highest activitv at lowtelnperatnre and pressure,is ultra-easily-rcducible and has better stability to heat and poison.
