阅读说明：本技术 从烃料流中除去杂质的方法及其在芳族烷基化方法中的用途 (Process for removing impurities from a hydrocarbon stream and its use in an aromatic alkylation process ) 是由 M·S·伊德 D·雷文 S·J·威格尔 B·T·勒弗劳斯 J·W·贝克曼 于 2018-03-19 设计创作，主要内容包括：公开了使用保护床材料从烃料流中除去杂质的方法。保护床材料包括包含沸石和中孔载体或粘合剂的组合物。沸石具有小于3的约束指数。中孔载体或粘合剂包括具有在累积孔径分布的50％(D<Sub>50</Sub>)处大于或等于20μm的粒径,小于1cc/g的孔体积和以重量计大于或等于75％的氧化铝含量的中孔金属氧化物。还公开了使用由所公开的方法处理以除去充当下游烷基化和/或烷基转移催化剂的催化剂毒物的杂质的不纯的进料料流生产单烷基化芳族化合物(例如,乙苯或枯烯)的方法。(Discloses a use protection bed materialA process for removing impurities from a hydrocarbon stream. The guard bed material comprises a composition comprising a zeolite and a mesoporous carrier or binder. The zeolite has a constraint index of less than 3. The mesoporous support or binder comprises a polymer having a pore size distribution at 50% (D) 50 ) A particle size of 20 μm or more, a pore volume of less than 1cc/g and an alumina content of 75% by weight or more. Also disclosed is a process for producing a monoalkylated aromatic compound (e.g., ethylbenzene or cumene) using an impure feed stream treated by the disclosed process to remove impurities that act as catalyst poisons for downstream alkylation and/or transalkylation catalysts.)
