Li+在不同交换度低硅铝比X型分子筛骨架中的分布的开题报告【摘要】X型分子筛是一种应用广泛的催化剂载体，在催化反应中起到载体和催化作用。随着X型分子筛的发展，人们对其结构和性质的研究越来越深入，其中离子交换度和硅铝比是两个重要的参数。本文将探讨不同离子交换度和硅铝比X型分子筛骨架中Li+分布的情况。以压力变换吸附法（PTA）和X射线衍射法（XRD）为主要手段，对产物进行分析。研究结果表明，随着离子交换度的增加，Li+在X型分子筛中的均匀分布更加明显；随着硅铝比的减少，Li+在X型分子筛中的容量也随之减少。因此，本文的研究具有一定的理论和实践价值。【关键词】Li+；X型分子筛；离子交换度；硅铝比；均匀分布【Abstract】X-typemolecularsieveisawidelyusedcatalystsupport,whichplaysacarrierandcatalyticroleincatalyticreactions.WiththedevelopmentofX-typemolecularsieves,people'sresearchontheirstructureandpropertieshasbecomemoreandmorein-depth,amongwhichionexchangecapacityandsilicon-aluminumratioaretwoimportantparameters.ThispaperwillexplorethedistributionofLi+inX-typemolecularsieveframeworkswithdifferentionexchangecapacitiesandsilicon-aluminumratios.Themainmeansofanalysisarepressureswingadsorptionmethod(PTA)andX-raydiffractionmethod(XRD).Theresearchresultsshowthatastheionexchangecapacityincreases,theuniformdistributionofLi+inX-typemolecularsievebecomesmoreobvious;asthesilicon-aluminumratiodecreases,thecapacityofLi+inX-typemolecularsievealsodecreases.Therefore,thisresearchhascertaintheoreticalandpracticalvalue.【Keywords】Li+;X-typemolecularsieve;ionexchangecapacity;silicon-aluminumratio;uniformdistribution
