Catalysts and Processes for Converting Aromatics

Methods and corresponding catalysts are provided for conversion of an aromatics feed containing C.sub.8+ aromatics, particularly C.sub.9+ aromatics, to form a converted product mixture comprising, e.g., benzene and/or xylenes. The aromatic feed can be converted in the presence of a catalyst that includes a mixture of a first zeolite having an MEL framework, such as ZSM-11, and a second zeolite having a MOR framework, such as mordenite, particularly a mordenite synthesized using TEA or MTEA as a structure directing agent. The weight ratio of the first zeolite to the second zeolite in the catalyst can be from 0.3 to 1.2, or from 0.3 to 1.1, or from 0.3 to 1.0. The catalyst can further include one or more metals supported on the catalyst, such as a combination of metals.

PROCESS FOR INTERCONVERSION OF OLEFINS WITH MODIFIED BETA ZEOLITE

Methods for interconverting olefins in an olefin-rich hydrocarbon stream include contacting the olefin-rich hydrocarbon stream with a catalyst system in an olefin interconversion unit to produce an interconverted effluent comprising ethylene and propylene. The contacting may be conducted at a reaction temperature from 450° C. to 750° C., a reaction pressure from 1 bar to 5 bar, and a residence time from 0.5 seconds to 1000 seconds. The catalyst system includes a framework-substituted beta zeolite. The framework-substituted beta zeolite has a *BEA aluminosilicate framework that has been modified by substituting a portion of framework aluminum atoms of the *BEA aluminosilicate framework with beta-zeolite Al-substitution atoms independently selected from the group consisting of titanium atoms, zirconium atoms, hafnium atoms, and combinations thereof.

Catalyst composition

Catalytic composition and structures made thereof

Methods use a catalytic composition built up from a ceramic material including a catalytic material and a first inorganic binder and a second inorganic binder and a catalytic structure made thereof. Preferably, the structure is made by a colloidal ceramic shaping technique. The structure is used for catalytic or ion exchange applications. The catalytic structures have excellent mechanical, physicochemical and catalytic properties.
