Abstract

The sodium form of Faujasite Y (Na-FAU) zeolite has been synthesized by the hydrothermal method, and it has been exchanged with ammonium sulphate and later with lanthanum (III) chloride solutions to obtain the La-FAU catalyst. The three zeolites Na-FAU, NH₄⁺-FAU and La-FAU have been characterized by microcrystalline X-ray diffraction, X-ray fluorescence, surface area, pore volume and Brönsted acid sites. The La-FAU catalyst has been successfully activated with boron trifluoride etherate, and it has been tested in the alkylation reaction of isobutane with isobutene up to 112 h of time on stream, since the raw La-FAU catalyst showed a rapid deactivation.

三氟化硼活化La-Faujasite沸石的合成及其作为异丁烷-异丁烯烷基化固体酸催化剂的应用

采用水热法合成了钠型Faujasite Y (Na-FAU)沸石，并与硫酸铵和氯化镧溶液进行交换，得到La-FAU催化剂。采用微晶x射线衍射、x射线荧光、比表面积、孔体积和Brönsted酸位对Na-FAU、NH4+-FAU和La-FAU三种分子筛进行了表征。用三氟化硼醚成功活化了La-FAU催化剂，并在异丁烷与异丁烯的烷基化反应中进行了长达112 h的测试，因为原始La-FAU催化剂表现出快速失活。
