  • PRODUCTION OF AROMATICS FROM RENEWABLE RESOURCES
    Publication number: 20130289324
    Abstract: Renewable oils are converted to aromatics, by contact with a catalytically-active form of gallium, for use in the petrochemical industry and/or for fuel blending components or additives. The renewable oil(s) feature high oxygen content, high H/C mole ratios, and high fatty acid or fatty acid ester content prior to heating and contact with the catalyst. The catalyst may be, for example, a gallium-doped version of one or more zeolite-alumina matrix catalysts with pore sizes having 10 oxygen atoms in the pore mouth, such as ZSM-5, ZSM-11, ZSM-23, MCM-70, SSZ-44, SSZ-58, SSZ-35, and ZSM-22. Aromatics-production from the renewable oils is enhanced at higher gallium-cation levels, with the preferred level being about 1.0 Ga/framework-Al. While various renewable oils, or “bio-oils,” may be used, algae oil has exhibited very high BTEX yields over the gallium cation catalyst, under conditions at or near 1 atm and approximately 400 degrees C.

  • Copper-containing zeolite catalysts
    Patent number: 5583081
    Abstract: A catalyst useful in the conversion of nitrogen oxides or in the synthesis of nitriles or imines from amines, formed by preparing an intimate mechanical mixture of a copper (II)-containing species, such as CuO or CuCl.sub.2, or elemental copper, with a zeolite having a pore mouth comprising 10 oxygen atoms, such as ZSM-5, converting the elemental copper or copper (II) to copper (I), and driving the copper (I) into the zeolite.

  • Gallium-containing zeolite catalysts
    Patent number: 5149679
    Abstract: A catalyst useful in the aromatization of light paraffins and other hydrocarbons conversion reactions, formed by preparing an intimate mechanical mixture of a gallium-containing species, such as Ga.sub.2 O.sub.3, with a zeolite having a pore mouth comprising 10 oxygen atoms, such as ZSM-5, preferably followed by treatment with a reducing agent, such as hydrogen.
