摘要： A catalyst, a process for using the catalyst whereby the catalyst effectively transalkylates C7, C9, and C10 aromatics to C8 aromatics are disclosed. The catalyst comprises a support such as mordenite plus a metal component. The catalyst provides an enhanced life and activity for carrying out the transalkylation reactions at relatively low temperatures. This is achieved by reducing the maximum particle diameter of cylindrical pellets to {fraction (1/32)} inch (0.08 cm) or a trilobe to {fraction (1/16)} inch (0.16 cm).

摘要： One exemplary embodiment can be a process using an aromatic methylating agent. Generally, the process includes reacting an effective amount of the aromatic methylating agent having at least one of an alkane, a cycloalkane, an alkane radical, and a cycloalkane radical with one or more aromatic compounds. As such, at least one of the one or more aromatic compounds may be converted to one or more higher methyl substituted aromatic compounds to provide a product having a greater mole ratio of methyl to phenyl than a feed.

摘要： A process for preparing a transalkylation catalyst, the catalyst itself, and a transalkylation process for using the catalyst are herein disclosed. The catalyst comprises rhenium metal on a solid-acid support such as mordenite, which has been treated with a sulfur-based agent. Such treatment reduces the amount of methane produced by metal hydrogenolysis in a transalkylation process wherein heavy aromatics like A9+ are reacted with toluene to produce xylenes. Reduced methane production relative to total light ends gas production results in lower hydrogen consumption and lower reactor exotherms.

摘要： A process for transalkylating aromatic hydrocarbon compounds, the process comprising introducing an aromatic hydrocarbon feed stream and a water source to a transalkylation zone. The feed stream contacts a catalyst in the transalkylation zone in the presence of water, and produces a reaction product stream comprising benzene and xylene. The invention includes methods to control the transalkylation process.
