求助 超稳Y分子筛做NH3-TPD酸量表征时,表征的条件是什么啊?我做过,欢迎参考!Applied Catalysis A: General, Volume 352, Issues 1–2, 15 January 2009, Pages 259-264Fuel, Volume 86, Issues 17–18, December 2007, Pages 2707-2713Applied Catalysis A: General, Volume 304, 10 May 2006, Pages 49-54One hundred milligrams of sample was placed in a quartz tubular reactor and pretreated at 500 C with an argon ?ow of 30 mL/min for 1 h and then cooled to 50 C. Ammonia (20% NH3/Ar) was introduced at a ?ow rate of 30 mL/min for 0.5 h at 50 8C, and then blown by an argon steam until a constant TCD level was attained; the reactor temperature was programmed to increase at a ramp rate of 10 C/min, and the amount of ammonia inef?uent was measured via TCD and recorded as function of temperature,查看更多
