ＸＲＤ、ＦＴ－ＩＲ和￣（２９）Ｓｉ、￣（２７）ＡｌＭＡＳＮＭＲ测试结果表明，水热处理过程中产生的非骨架铝可能是造成这种热稳定性变差的原因。
2.
It has been shown that all the ultrastable Y zeolites,especially FSEY and HSY,have better thermal stability than NH_4Yzeolite, However,after steam treatment, the thermal stability ofall ultrastable Y zeolites,especially FSEY and HSY,were decreased.
本文对Y沸石及超稳Y沸石的热稳定性进行了探讨,结果表明,各种超稳Y沸石的热稳定性都比Y沸石高;水热处理前各种超稳Y沸石热稳定性彼此相差较大,但经水热处理后差距变小并且晶格破坏温度都有所降低,非骨架铝可能是造成这种热稳定性变差的原因。
