    • Disclosed is an alkylation reactor for preparing ethylbenzene. The reactor comprises a monolith catalyst system that includes a monolith support impregnated orco-formed with a catalyst suitable to catalyze the alkylation of benzene with ethylene. The catalyst may be selected from, for example, zeolites such as beta zeolite and MCM-22 zeolite, and fixed super acids. Also disclosed is a method of preparing ethylbenzene by alkylating a mixture of benzene and ethylene in an alkylation reactor comprising a monolith catalyst system, to including a monolith support impregnated or co-formed with a suitable catalyst. In one embodiment the invention provides a convenient means of upgrading an existing reactor that has previously been used for conventional liquid phase alkylations such as those catalyzed by aluminum trichloride. The inventive alkylation method may be effectively and advantageously carried out under critical or near critical conditions, if desired.
    • 公开了一种用于制备乙苯的烷基化反应器。 所述反应器包含整体式催化剂体系,所述整体式催化剂体系包括浸渍有或适于催化苯与乙烯的烷基化的催化剂的整体载体。 催化剂可以选自例如沸石例如β沸石和MCM-22沸石,以及固定超酸。 还公开了通过在包含整体式催化剂体系的烷基化反应器中将苯和乙烯的混合物烷基化来制备乙苯的方法,以包括浸渍或与合适的催化剂共成形的整料载体。 在一个实施方案中,本发明提供了一种方便的方法来升级先前用于常规液相烷基化的现有反应器,例如由三氯化铝催化的那些。 如果需要,本发明的烷基化方法可以在临界或接近临界条件下有效且有利地进行。

    • A process for the production of ethylbenzene by the ethylation of benzene in the critical phase over a molecular sieve aromatic alkylation catalyst comprising cerium-promoted zeolite beta. An aromatic feedstock having a benzene content of at least 90 wt.% is supplied into a reaction zone and into contact with the cerium-promoted zeolite beta having a silica/alumina mole ratio within the range of 50-150 and a cerium-aluminum ratio of 0.5-1.5. Ethylene is supplied to the alkylation reaction zone in an amount to provide a benzene/ethylene mole ratio of 1-15. The reaction zone is operated at temperature and pressure conditions in which benzene is in the super critical phase to cause ethylation of the benzene in the presence of the cerium zeolite beta alkylation catalyst. An alkylation product is produced containing ethylbenzene as a primary product with the attendant production of heavier alkylated by-products of no more than 60 wt.% of the ethylbenzene. The critical phase alkylation reaction may be followed by the transalkylation of a polyalkylated aromatic component.
    • 通过在包含铈促进的沸石β的分子筛芳族烷基化催化剂上在临界相中苯的乙基化生产乙苯的方法。 将苯含量至少为90重量%的芳族原料供入反应区并与二氧化硅/氧化铝摩尔比在50-150范围内的铈促进沸石β接触,并将铈铝比 为0.5-1.5。 将乙烯以提供1-15的苯/乙烯摩尔比的量供应到烷基化反应区。 反应区在温度和压力条件下操作,其中苯处于超临界相中,以在铈沸石β烷基化催化剂存在下引起苯的乙基化。 生产含有乙苯作为主要产品的烷基化产物,伴随地生产不超过60重量%乙苯的重质烷基化副产物。 关键相烷基化反应之后可以是多烷基化芳族化合物的烷基转移。
