| 20110230572 | Water-Forming Hydrogenation Reactions Utilizing Enhanced Catalyst Supports and Methods of Use - Improved reaction efficiencies are achieved by the incorporation of enhanced hydrothermally stable catalyst supports in various water-forming hydrogenation reactions or reactions having water-containing feeds. Examples of water-forming hydrogenation reactions that may incorporate the enhanced hydrothermally stable catalyst supports include alcohol synthesis reactions, dehydration reactions, hydrodeoxygenation reactions, methanation reactions, catalytic combustion reaction, hydrocondensation reactions, and sulfur dioxide hydrogenation reactions. Advantages of the methods disclosed herein include an improved resistance of the catalyst support to water poisoning and a consequent lower rate of catalyst attrition and deactivation due to hydrothermal instability. Accordingly, higher efficiencies and yields may be achieved by extension of the enhanced catalyst supports to one or more of the aforementioned reactions. | 09-22-2011 |

| 20090050327 | Switching Apparatus Between Independent Control Systems for a Subsurface Safety Valve - A system is provided for switching between redundant control systems for a subsurface safety valve (SSV) while being able to isolate the closure spring from hydrostatic pressure in the control line of the system that is not being used. There are two control lines that connect to discrete operating pistons that are both coupled to the flow tube. Each operating piston is connected to a control rod with the control rods terminating near opposed ends of a pivoting member. Pushing down on one rod pushes up on the other rod so that the other rod is held supported and the hydrostatic pressure in its associated control line doesn't affect the force needed by the closure spring to close the SSV. Releasing control line pressure puts the system in neutral to allow either of the systems to be reselected. | 02-26-2009 |
