1.
When the titania content in the zeolites is less than 1 5%, titania species is present only as highly dispersed framework titania TiO x in all zeolite samples.
当钛含量达到 2 0 %以上时 ,不同方法合成的钛硅分子筛中钛的分散状态显著不同 ,其中以TiCl3 合成的分子筛中骨架钛的含量最高 ,而杂晶相锐钛矿含量最低 ,同时催化氯丙烯环氧化活性也最高 。
4) TiC skeleton
碳化钛骨架
1.
TiC skeleton preforms with volume fraction of 15%～70% can be fabricated by polymer foam immersion and vacuum sintered method.
用泡沫塑料浸渍法成形、真空烧结的方法可以制备体积骨架分数在 1 5 %～ 70 %的碳化钛骨架预制件。
5) non-framework aluminum
非骨架铝
1.
The type and the chemical state of non-framework aluminum and the related influence on zeolite acidity were investigated by means of 27Al MAS NMR,N2 adsorption-desorption,XRD Rietveld refinement.
采用27Al MAS NMR、N2吸附-脱附、IR等表征技术及XRD Rietveld结构精修的方法,通过清除和交换引入非骨架铝,探讨了USY沸石中非骨架铝的形态。
2.
Being treated by water vapor at 371 ℃, the non-framework aluminum species, transformed from part of the framework aluminum, had much effects on shape-selective disproportionation of toluene.
HZSM-5分子筛经过371℃水蒸汽处理后,分子筛的部分骨架铝脱出,形成非骨架铝物种,该非骨架铝物种对甲苯择形歧化反应具有较大影响。
6) thermal stability
非骨架铝
1.
It has been show that all ultrastable Y zeolites,especially FSEY and HSY,have betterthermal stability than NH_4Y zeolite.
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。
