SnAlPO₄-5 molecular sieves were hydrothermally synthesized using SnCl₂·2H₂O as the tin source, and were verified that divalent tin was incorporated into the framework by isomorphous substitution of trivalent aluminum, and increasing the numbers of Brønsted and Lewis acid sites relative to those in AlPO₄-5. The molecular sieves were used to fabricate hybrid supports with alumina and then were loaded with active metals to obtain NiW catalysts. The hydrodesulfurization (HDS) of dibenzothiophene (DBT) were evaluated for the catalytic activity of the catalysts. Because of the higher number of weak acid sites, much greater average number of slab layers and higher dispersion of WS₂, the HDS rate of DBT at 280 °C is improved from 49.6% for the NiW/(AlPO₄-5+Al₂O₃) catalyst to 82.2% for the NiW/(Sn_0.12AlPO₄-5+Al₂O₃) catalyst. Moreover, the highly active NiW/(Sn_0.12AlPO₄-5+Al₂O₃) catalyst obviously increases the product of the direct desulfurization route in the DBT HDS, which is beneficial for reducing hydrogen consumption in the industrial applications.

以SnCl ₂ ·2H ₂ O为锡源水热合成了SnAlPO ₄ -5分子筛，并证实三价铝的同构取代并增加了Brønsted和Lewis酸位的相对数目，从而将二价锡掺入骨架中到AlPO ₄ -5中的那些。分子筛用于制备氧化铝的杂化载体，然后负载活性金属以获得NiW催化剂。评价了二苯并噻吩（DBT）的加氢脱硫（HDS）的催化活性。由于弱酸位点的数量更多，因此平板层的平均数量更多，WS _2的分散度更高，则280°C下DBT的HDS率从NiW /（AlPO ₄ -5 + Al ₂ O ₃）催化剂的49.6％提高到NiW /（Sn _0.12 AlPO ₄ -5 + Al ₂ O ₃）的82.2％。）催化剂。而且，高活性NiW /（Sn _0.12 AlPO ₄ -5 + Al ₂ O ₃）催化剂明显增加了DBT HDS中直接脱硫途径的产物，有利于降低工业应用中的氢消耗。
