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： An improved process is disclosed for the selective disproportionation of toluene. The process preferably uses a disproportionation catalyst comprising a pentasil type zeolite such as MFI that is bound with aluminum-phosphate. Running the process at a toluene conversion greater than about 30 wt-% and at a hydrogen-to-hydrocarbon ratio less than 3.0, and especially a ratio of 0.1 to 1.0, improves the maximum yield of para-xylene. Optional periodic rejuvenation by increasing the hydrogen-to-hydrocarbon ratio removes some carbon deposits and restores catalyst activity. An inert diluent gas assists in selective pre-coking of the catalyst as well.

摘要： An improved process is disclosed for the selective disproportionation of toluene. The process uses a zeolitic catalyst which is oil-dropped in an amorphous aluminum phosphate binder and optionally is selectively precoked prior to toluene disproportionation. The catalyst and process provide enhanced selectivity for the production of paraxylene.

摘要： A reforming process, selective for the dehydrocyclization of paraffins to aromatics, is effected using a catalyst containing multiple Group VIII (8-10) noble metals having different gradients within the catalyst and a nonacidic large-pore molecular sieve. The use of this bed of catalyst results in greater selectivity of conversion of paraffins to aromatics and improved catalyst stability, particularly in the presence of small amounts of sulfur.
