| 20080269443 | Methods of oligomerizing olefins - The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene. | 10-30-2008 |
| 20080286170 | Parallel batch reactor - In one embodiment, a parallel batch reactor for effecting chemical reactions includes a vessel block comprising reactor vessels for receiving components of a reaction and a valve block removably attached to the vessel block. The valve block includes a first plurality of valves in fluid communication with an inlet port for supplying pressurized fluid to the reactor vessels and configured to fluidically isolate one or more of the reactor vessels from at least one of the other reactor vessels. The valve block further includes a second plurality of valves in fluid communication with the reactor vessels for injecting chemical components into the pressurized reactor vessels or sampling chemical components from the pressurized reactor vessels. The vessel block and valve block are configured to sustain an operating pressure of at least 15 psig. | 11-20-2008 |
| 20080286171 | Parallel batch reactor with pressure monitoring - In one embodiment, a parallel batch reactor for effecting chemical reactions includes a plurality of reactor vessels for receiving components of a reaction, an inlet port for receiving pressurized fluid, and a plurality of valves configured to transfer fluid from the inlet port to the reactor vessels and fluidically isolate one or more of the reactor vessels from at least one of the other reactor vessels. The reactor further includes a pressure monitoring system comprising an array of pressure sensors configured to sense pressure in the reactor vessels. Each of the pressure sensors is aligned with one of the plurality of reactor vessels and located external to the reactor vessels and fluid passageways in fluid communication with the reactor vessels. | 11-20-2008 |
| 20080286174 | Methods for chemical reactions in a parallel batch reactor - In one embodiment, a parallel batch reactor generally includes a plurality of reactor vessels and a plurality of valves configured to allow flow into the reactor vessels when a gas is supplied to the reactor at a pressure higher than a pressure within the reactor vessels and restrict flow from the reactor vessels. A method includes inserting chemical components into the reactor vessels, supplying a first gas to the reactor vessels to pressurize the reactor vessels, stopping supply of the first gas, and supplying a second gas to the reactor at a lower pressure than a pressure within the reactor vessels. The second gas passes through the valves and into the reactor vessels when the pressure within the reactor vessels drops below the pressure of the second gas. | 11-20-2008 |

| 20100081577 | REACTOR SYSTEMS AND METHODS - A reactor system includes a housing and a plurality of reactors at least partially contained in the housing. The reactors each have a containment structure enclosing an internal space in the reactor. The containment structure including a circumferential sidewall having opposite ends and surrounding at least a portion of said internal space. The sidewall has a thermal mass and a sidewall heater adjacent an exterior surface of the sidewall. The ratio of the thermal mass of the sidewall to a volume of the portion of the internal space that is surrounded by the sidewall is relatively low. | 04-01-2010 |
