摘要： An improved process combination is disclosed for the selective disproportionation of toluene. The combination comprises selective hydrogenation of a toluene feedstock followed by disproportionation using a zeolitic catalyst which is oil-dropped in an aluminum phosphate binder to achieve a high yield of paraxylene. Optionally, the catalyst is selectively precoked prior to toluene disproportionation. The catalyst and process provide improved selectivity for the production of paraxylene.

摘要： A process for aromatic transalkylation and olefin reduction of a feed stream is disclosed. Transalkylation conditions produce xylenes and reduced olefins in the feed. The process may be used in a xylene production facility to minimize or avoid the necessity of feedstock pretreatment such as hydrotreating, hydrogenation, or treating with clay and/or molecular sieves.

摘要： A transalkylation process for reacting carbon number nine aromatics with toluene to form carbon number eight aromatics such as para-xylene is herein disclosed. The process is based on the discovery that deactivating contaminants present in typical hydrocarbon feeds, such as chlorides, can be removed with an alumina guard bed prior to contacting with a transalkylation catalyst. Effective transalkylation catalysts have a solid-acid component such as mordenite, and a metal component such as rhenium. The invention is embodied in a process, a catalyst system, and an apparatus. The invention provides for longer catalyst cycle life when processing aromatics under commercial transalkylation conditions.

摘要： An improved process is disclosed for the selective disproportionation of toluene. The process preferably uses a disproportionation catalyst comprising MFI bound with alumina phosphate. Running the process at a hydrogen to hydrocarbon ratio between 0.2 to 0.5 improves the yield of para-xylene. Optional periodic rejuvenation by increasing the hydrogen to hydrocarbon ratio removes some carbon deposits and restores catalyst activity.
