| 20090023966 | Treatment of Alkylation Catalyst Poisons - Alkylation processes are described herein. The alkylation process generally includes contacting an input stream including benzene with an alkylation catalyst and an alkylating agent to form an alkylation output stream including ethylbenzene. The alkylation process further includes contacting at least a portion of the alkylation output stream with a transalkylation catalyst and a benzene source to form a transalkylation output stream, wherein the benzene source is selected to minimize the amount of alkylation catalyst poisons contacting the alkylation catalyst. | 01-22-2009 |
| 20090054715 | Method and Apparatus for Addition of Aqueous Solutions to High Temperature Processes - Methods and systems for extending the life of a dehydrogenation catalyst are described herein. For example, one embodiment includes providing a reaction vessel loaded with a dehydrogenation catalyst with a feedstream via a conduit in operable communication with the reaction vessel. The feedstream may include an alkyl aromatic hydrocarbon and the dehydrogenation catalyst may be adapted to convert the alkyl aromatic hydrocarbon to a vinyl aromatic hydrocarbon. The feedstream may be contacted with an aqueous catalyst life extender, wherein the aqueous catalyst life extender enters the conduit at a linear velocity sufficient to prevent vaporization of the catalyst life extender in the conduit prior to contact with the feedstream. | 02-26-2009 |
| 20090118557 | Dehydrogenation of alkyl aromatics - Dehydrogenation of a reactor system of one or more vertically oriented flow reactors equipped with a system for introducing a catalyst extender into the inlet of the reactor. A vertically oriented radial flow reactor comprises inner and outer reactor tubes having perforated wall members extending longitudily of the reactor and defining an annulus containing a dehydrogenation catalyst. A supply line to the reactor is equipped with a rotation vane. An injection nozzle comprising a coaxial flow tube extends into the supply line downstream of the vane. The coaxial flow tube has an interior chamber and an annular chamber surrounding the interior chamber and extending into the supply line along with the interior chamber. The interior chamber is connected to a catalyst extender source and the annular chamber is connected to a source of a carrier gas which is effective to disperse the extender within feedstock flowing into the reactor. | 05-07-2009 |
| 20090149685 | Treatment of Alkylation Catalyst Poisons with Dehydrogenation - Methods and processes for reducing alkylation catalyst poisoning are described herein. Such methods generally include providing a dehydrogenation system including a dehydrogenation reactor and a separation system, wherein the separation system includes a first column and a second column, introducing an alkyl aromatic hydrocarbon into the dehydrogenation reactor, contacting the alkyl aromatic hydrocarbon with a dehydrogenation catalyst disposed within the dehydrogenation reactor to form a dehydrogenation output stream comprising a vinyl aromatic hydrocarbon, passing at least a portion of the dehydrogenation output stream to first column, recovering a first overhead fraction including benzene and a first bottoms fraction from the first column, passing at least a portion of the benzene from the first column to an alkylation system including an alkylation catalyst, passing the first bottoms fraction from the first column to the second column, recovering a second overhead fraction and a second bottoms fraction from the second column, withdrawing offtest from effluent streams selected from the dehydrogenation output stream, the first bottoms fraction, the second bottoms fraction and combinations thereof to form withdrawn offtest and introducing the withdrawn offtest into the separation system downstream from the first column. | 06-11-2009 |
