  • Alkylation process using UZM-8 zeolite
    Patent number: 7268267
    Abstract: A process for the alkylation of aromatics with olefins using a solid catalyst bed containing UZM-8 zeolite is disclosed. A polyalkylated aromatic is passed to the catalyst bed to reduce the concentration of the olefin at alkylation conditions. A portion of the effluent recovered from the catalyst bed may be recycled to the catalyst bed. Such operation can decrease the catalyst deactivation rate and the formation of diphenylalkanes. The process disclosed herein is applicable to processes for the production of a wide variety of commercially important alkylated aromatics, including ethylbenzene and cumene.

  • Process for the removal of nitrogen compounds from a fluid stream
    Patent number: 7205448
    Abstract: At lower temperatures an acidic molecular sieve adsorbent preferentially adsorbs water and basic organic nitrogen compounds over weakly basic organic nitrogen compounds such as nitrites. Elevated temperatures improve the capacity of acidic molecular sieve adsorbents to adsorb nitrites in the presence of water.

  • HYDROCARBON CONVERSION PROCESSES USING A CATALYST COMPRISING A UZM-8HS COMPOSITION
    Publication number: 20060247480
    Abstract: Hydrocarbon conversion processes using a new family of zeolites identified as UZM-8HS are described. The UZM-8HS zeolite are derived from UZM-8 zeolites by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8HS zeolites 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.

  • High silica zeolites: UZM-8HS
    Publication number: 20060159615
    Abstract: A family of crystalline aluminosilicate zeolites designated UZM-8HS and derived from UZM-8 have been synthesized. The aluminum content of the UZM-8HS is lower than that of the starting UZM-8 thus changing its ion exchange capacity and acidity. These UZM-8HS are represented by the empirical formula: M1an+Al(1?x)ExSiy?Oz? and are prepared by treatments such as acid extraction and AFS treatments.

  • Crystalline aluminosilicate zeolitic composition: UZM-15
    Patent number: 6890511
    Abstract: An aluminosilicate zeolite and substituted versions designated UZM-15 have been synthesized.
