  • Publication number: 20110178354
    Abstract: One exemplary embodiment can be a process using an aromatic methylating agent. Generally, the process includes reacting an effective amount of the aromatic methylating agent having at least one of an alkane, a cycloalkane, an alkane radical, and a cycloalkane radical with one or more aromatic compounds. As such, at least one of the one or more aromatic compounds may be converted to one or more higher methyl substituted aromatic compounds to provide a product having a greater mole ratio of methyl to phenyl than a feed.

  • Patent number: 7638667
    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.
