  • Reactivation of aromatics alkylation catalysts
    Patent number: 6781025
    Abstract: The present invention provides a process for regenerating a spent aromatics alkylation or transalkylation catalyst comprising a molecular sieve by contacting the spent catalyst with an oxygen-containing gas at a temperature of about 120 to about 600° C. and then contacting the catalyst with an aqueous medium, such as an ammonium nitrate solution, an ammonium carbonate solution or an acetic acid solution.
    Type: Grant
    Filed: July 11, 2001
    Date of Patent: August 24, 2004
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Ajit B Dandekar, Michael Hryniszak, David Lawrence Stern, Jeffrey Scott Beck

  • Aluminosilicate molecular sieve
    Patent number: 6306362
    Abstract: The present invention is directed to a large-pore aluminosilicate molecular sieve comprising alumina and silica, where the ratio of SiO2/Al2O3 ranges from about 75 to 600, and its method of preparation. The large-pore aluminosilicate molecular sieve of the present invention has the ability to catalyze reactions involving particularly bulky transition states or large molecules.

  • Xylene isomerization
    Patent number: 6028238
    Abstract: A process is described for isomerizing a feed which contains ethylbenzene and xylene, which process comprises the steps of:(a) contacting the feed under ethylbenzene conversion conditions with a particulate first catalyst component which comprises a molecular sieve having a constraint index of 1-12, the particles of said first catalyst component having a surface to volume ratio of about 80 to less than 200 inch.sup.-1 and the contacting step converting ethylbenzene in the feed to form an ethylbenzene-depleted product; and then(b) contacting the ethylbenzene-depleted product under xylene isomerization conditions with a second catalyst component.
    Type: Grant

  • Direct thermal synthesis and ceramic applications of poly(borazylenes) and borazine/polyhedral borane oligomers
    Patent number: 6025454
    Abstract: Direct thermal syntheses in the absence of catalyst, of poly(borazylenes) and of oligomers of borazine with polyhedral boranes, carboranes or heteroboranes are disclosed. The products of these syntheses are precursors to BN or other boron-containing ceramics.
