| 20090159505 | HEAVY OIL UPGRADE PROCESS INCLUDING RECOVERY OF SPENT CATALYST - A process to upgrade heavy oil and convert the heavy oil into lower boiling hydrocarbon products is provided. The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via a filtration assembly. The filtration assembly has a least a filtration unit employing at least a membrane for separating heavy oil from the catalyst particles. Valuable metals can be recovered from catalyst particles for subsequent re-use in a catalyst synthesis unit, generating a fresh slurry catalyst. | 06-25-2009 |
| 20090163350 | HEAVY OIL UPGRADE PROCESS INCLUDING RECOVERY OF SPENT CATALYST - A process to upgrade heavy oil and convert the heavy oil into lower boiling hydrocarbon products is provided. The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via membrane filtration. In one embodiment, dynamic filtration is used for the separation of the heavy oil from the catalyst particles. Valuable metals can be recovered from catalyst particles for subsequent re-use in a catalyst synthesis unit, generating a fresh slurry catalyst. | 06-25-2009 |

| 20090163347 | Recovery of slurry unsupported catalyst - A method of recovering unsupported fine catalyst from heavy oil comprises combining a slurry comprising unsupported fine catalyst in heavy oil with solvent to form a combined slurry-solvent stream. The combined slurry-solvent stream is filtered in a deoiling zone. A stream comprising unsupported fine catalyst and solvent is recovered from the deoiling zone. Unsupported fine catalyst is separated from the stream comprising unsupported fine catalyst and solvent. Filtering in the deoiling zone can comprise filtering the slurry and solvent through a cross-flow microfiltration unit, recovering a retentate stream of the cross-flow microfiltration unit, combining the retentate stream of the cross-flow microfiltration unit with solvent to form a combined retentate-solvent stream, and filtering the combined retentate-solvent stream through a cross-flow microfiltration unit. | 06-25-2009 |
| 20090163348 | Recovery of slurry unsupported catalyst - A method of recovering unsupported fine catalyst from heavy oil comprises combining a slurry comprising unsupported fine catalyst in heavy oil with solvent to form a combined slurry-solvent stream. The combined slurry-solvent stream is filtered in a deoiling zone. A stream comprising unsupported fine catalyst and solvent is recovered from the deoiling zone. Unsupported fine catalyst is separated from the stream comprising unsupported fine catalyst and solvent. The deoiling zone can comprise a membrane that is rapidly displaced in a horizontal direction. | 06-25-2009 |

| 20090040989 | High performance wireless networks using distributed control - A design and proof of concept of a new type of WLAN, complete with simulation and results from the simulation has been described. Each AP Node is implemented as a self-contained embedded OS unit, with all algorithms resident in its Operating system. The normal day-to-day functioning of the AP node is based entirely on resident control algorithms. Upgrades are possible through a simple secure communications interface supported by the OS kernel for each AP node. Benefits provided by a wireless network, as proposed in this invention, are that: it installs out of the box; the network is self-configuring; the network is redundant in that mesh network formalism is supported, ensuring multiple paths; load balancing is supported; there is no single point of failure; allows for decentralized execution; there is a central control; it is network application aware; there is application awareness; there is automatic channel allocation to manage and curtail RF interference, maximize non interference bandwidth and enable seamless roaming between adjoining wireless sub networks (BSS) and it supports the wireless equivalent for switching—for seamless roaming requirements. | 02-12-2009 |
