在 FCC 汽油中，噻吩化合物与进料中的烯烃进行烷基化，然后蒸馏重质硫化合物，是传统加氢脱硫消除硫的良好替代方案。在几种酸性催化剂中，二氧化硅负载的 H3PW12O40 中心点 6H(2)O (HPW) 被发现是 3-甲基噻吩 (3MT) 与 2-甲基-2-丁烯 (2M2B) 烷基化的最佳催化剂，作为模型反应，在 358 K 氮气下在非均相液相体系中进行。该催化剂的制备已针对该反应进行了优化，连续催化测试证明，与之前在工业过程中测试和使用的传统负载型磷酸或沸石相比，该固体非常有前景。 (C) 2008 Elsevier B.V. 保留所有权利。
In FCC gasolines, thiophenic compounds alkylation with olefins of the feed followed by distillation of heavy sulfur compounds is a good alternative to classical hydrodesulfurization to eliminate sulfur. Among several acidic catalysts, silica-supported H3PW12O40 center dot 6H(2)O (HPW) has been found to be the best catalyst for the alkylation of 3-methylthiophene (3MT) with 2-methyl-2-butene (2M2B) taken as a model reaction in heterogeneous liquid phase systems at 358 K under nitrogen. The preparation of this catalyst has been optimized for this reaction and continuous catalytic tests have proved that this solid was very Promising compared to traditional supported phosphoric acid or zeolites previously tested and used in industrial processes.
