  • Publication number: 20080221375
    Abstract: 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.

  • Patent number: 7091390
    Abstract: Hydrocarbon conversion processes using a new family of zeolites identified as UZM-8 and UZM-8HS are described. The UZM-8 and UZM-8HS are related in that the UZM-8HS are derived from the UZM-8 zeolite by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8 and -8HS have unique x-ray diffraction patterns. These zeolites can be used in alkylation of aromatics, transalkylation of aromatics, isomerization of aromatics and alkylation of isoparaffins.

  • Patent number: 6958425
    Abstract: The use of transalkylation catalysts to react heavy aromatic compounds of carbon number nine (and heavier carbon numbers) with benzene to form carbon number eight aromatics is disclosed. The catalyst system preserves ethyl-group species on the heavier aromatics that are otherwise de-ethylated over most gas-phase transalkylation catalysts to form undesired ethane gas with benzene or toluene. The catalyst system also promotes methyl-group species transalkylation at selected conditions. Thus, by using the transalkylation system, a greater yield of para-xylene or other carbon number eight aromatics may be achieved overall within an integrated aromatics complex.

  • Patent number: 6512144
    Abstract: Processes for oxidizing hydrocarbons using a new family of crystalline manganese phosphate compositions have been developed. These compositions have an extended network which network can be a one-, two-, or three-dimensional network. The composition has an empirical formula of: (Aa+)v(Mnb+)(Mc+)xPyOz where A is a structure directing agent such as an alkali metal, M is a metal such as Al, Fe3+ and “b” is the average manganese oxidation state and varies from greater than 2.0 to a maximum of 3.0.
