| 20100069694 | Xylene Isomerization Process and Apparatus - Xylene isomerization processes, especially those processes in which ethylbenzene is also converted, are beneficially affected by adding benzene to the feed. | 03-18-2010 |
| 20100089796 | Layered Composition and Processes for Preparing and Using the Composition - A layered composition which can be used in various processes has been developed. The composition comprises an inner core such as a cordierite core and an outer layer comprising a refractory inorganic oxide, a fibrous component and an inorganic binder. The refractory inorganic oxide layer can be alumina, zirconia, titania, etc. while the fibrous component can be titania fibers, silica fibers, carbon fibers, etc. The inorganic oxide binder can be alumina, silica, zirconia, etc. The layer can also contain catalytic metals such as gold and platinum plus other modifiers. The layered composition is prepared by coating the inner core with a slurry comprising the refractory inorganic oxide, fibrous component, an inorganic binder precursor and an organic binding agent such as polyvinyl alcohol. The composition can be used in various hydrocarbon conversion processes. | 04-15-2010 |

| 20100125160 | Selective Aromatics Isomerization Process - This invention is drawn to a process for isomerizing a non-equilibrium mixture of xylenes and ethylbenzene using a catalyst comprising a zeolite having specific particle-size characteristics, a platinum-group metal and a silica binder. A relatively minimal amount of hydrogen is supplied to the process on a once-through basis, resulting in low saturation of aromatics while achieving effective xylene isomerization with reduced processing costs. | 05-20-2010 |
| 20110046427 | XYLENE PRODUCTION PROCESSES WITH INTEGRATED FEEDSTOCK TREATMENT - 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. | 02-24-2011 |
