摘要： This invention embodies a catalyst and a process for transalkylation of C7, C9, and C10 aromatics to obtain a high yield of xylenes. The catalyst comprises a novel UZM-14 catalytic material comprising globular aggregates of crystallites having a MOR framework type with a mean crystallite length parallel to the direction of the 12-ring channels of about 60 nm or less and a mesopore volume of at least about 0.10 cc/gram. The UZM-14 catalyst is particularly active and stable in a transalkylation process.

摘要： The present invention is a process for transalkylating aromatic hydrocarbon compounds, the process comprising introducing an aromatic hydrocarbon feed stream into a transalkylation zone to yield high-purity benzene as a byproduct while meeting transalkylation objectives. The feed stream contacts a catalyst in the transalkylation zone under conditions adjusted to control benzene purity as well as transalkylation performance.

摘要： A process for aromatic transalkylation and olefin reduction of a feed stream is disclosed. Transalkylation conditions provide a product having increased xylene concentration and reduced olefin concentration relative to the feed. The process may be used in a xylene production facility to minimize or avoid the necessity of feedstock pretreatment such as hydrotreating, hydrogenation, or treating with clay and/or molecular sieves.
