| 20110186858 | Gallium Nitride Power Devices Using Island Topography - A semiconductor device in provided having a substrate and a semiconductor layer formed on a main surface of the substrate. A plurality of first island electrodes and a plurality of second island electrodes are placed over the semiconductor layer. The plurality of first island electrodes and second island electrodes are spaced apart from each other so as to be alternatively arranged to produce two-dimensional active regions in all feasible areas of the semiconductor layer. Each side of the first island electrodes is opposite a side of the second island electrodes. The semiconductor device can also include a plurality of strip electrodes that are formed in the regions between the first island electrodes and the second island electrodes. The strip electrodes serve as the gate electrodes of a multi-island transistor. The first island electrodes serve as the source electrodes of the multi-island transistor. The second island electrodes serve as the drain electrodes of the multi-island transistor. A plurality of connections to the gate electrodes are provided at each interstice defined by corners of the first island electrodes and the second island electrodes. | 08-04-2011 |

| 20100018905 | Deep hydrodesulfurization of hydrocarbon feedstreams - The distillate catalytic hydrodesulfurization of hydrocarbon fuels wherein the optimum hydrogen treat gas rate to maximize desulfurization is determined and introduced into the reaction zone to maintain a controlled amount of hydrogen at the surface of the catalyst during hydrodesulfurization. | 01-28-2010 |
| 20110219770 | METHODS OF UTILIZING WASTE HEAT FOR CREATING A PRESSURIZED WORKING FLUID - A method of utilizing waste heat to create a pressurized working fluid is disclosed. The method includes providing a vessel containing a sorbent system, introducing a feed of waste heat to a heat exchanger external to the vessel to heat a feed of working fluid, introducing the heated working fluid from the heat exchanger to the vessel to obtain pressurized working fluid, and directing the pressurized working fluid from the vessel to a work component. The method is particularly suited to make use of waste heat an industrial process, (e.g., a chemical processing or petrochemical refining operation) in which low grade heat source(s) are used to drive the sorption system. | 09-15-2011 |
| 20110219802 | SORPTION SYSTEMS HAVING IMPROVED CYCLE TIMES - The present invention relates to process modifications and apparatus designs that are conducive towards minimizing temperature swings (ΔT) useful to yield operating pressures that provide work and/or refrigeration (e.g., electricity and/or refrigeration) in sorption systems. Such process modifications and designs are particularly suited to make use of waste heat an industrial process, (e.g., a chemical processing or petrochemical refining operation) in which low grade heat source(s) are used to drive the sorption system. | 09-15-2011 |
| 20110232305 | SYSTEMS AND METHODS FOR GENERATING POWER AND CHILLING USING UNUTILIZED HEAT - The present application provides a sorption system for generating power and chilling that includes at least one absorber to absorb a working fluid in a liquid sorbent, a pump in fluid communication with the absorber to yield a feed of pressurized liquid sorbent and absorbed working fluid, a heat source to heat the feed of pressurized liquid sorbent and absorbed working fluid to yield a feed of working fluid at a supercritical state, a generator in fluid communication with the feed of working fluid at a supercritical state to yield power and a feed of working fluid in an at least partially condensed state, and an evaporator in fluid communication with the feed of working fluid in the at least partially condensed state to yield chilling and uncondensed working fluid. Additional systems and method for the generating power and chilling are provided. | 09-29-2011 |
| 20110232493 | METHOD OF PROTECTING A SOLID ADSORBENT AND A PROTECTED SOLID ADSORBENT - The present application provides a protected solid adsorbent that includes a solid adsorbent substrate and a surface layer at least partially coating the solid adsorbent substrate, the surface layer being generally permeable to an active agent. Additionally, a process for protecting a solid adsorbent and an adsorption system that includes a vessel containing the protected solid adsorbent is provided. | 09-29-2011 |

| 20120122230 | METHODS FOR IDENTIFYING HIGH FOULING HYDROCARBON AND FOR MITIGATING FOULING OF PROCESS EQUIPMENT - Methods for determining the fouling propensity of a hydrocarbon stream and for reducing fouling are provided. In one method, the fouling propensity of a hydrocarbon stream is determined by obtaining a parameter value indicative of the fouling propensity at no less than two different temperatures, and an activation energy of fouling by the hydrocarbon stream is derived therefrom. In another method, the thus obtained parameter value at no less than two different temperatures and the activation energy are used to select proper heating fluids and operating temperature and to determine whether to add an antifoulant to the hydrocarbon stream to reduce fouling at a given temperature. | 05-17-2012 |
