摘要:
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.
摘要:
One exemplary embodiment can be a process for increasing a mole ratio of methyl to phenyl of one or more aromatic compounds in a feed. The process can include reacting an effective amount of one or more aromatic compounds and an effective amount of one or more non-aromatic compounds to convert about 90%, by weight, of one or more C6+ non-aromatic compounds.

The process can include reacting an effective amount of one or more aromatic compounds and an effective amount of one or more aromatic methylating agents to form a product having a mole ratio of methyl to phenyl of at least about 0.1:1 greater than the feed.

摘要:
A reforming process, selective for the dehydrocyclization of paraffins to aromatics, is effected using a catalyst containing multiple Group VIII (8-10) noble metals having different gradients within the catalyst and a nonacidic large-pore molecular sieve. The use of this bed of catalyst results in greater selectivity of conversion of paraffins to aromatics and improved catalyst stability, particularly in the presence of small amounts of sulfur.
