| 20080318764 | Catalytic Naphtha Cracking Catalyst and Process - A process is disclosed for enhancing the production of light olefins using a catalyst with small pores. The catalyst comprises a molecular sieve having 10 membered rings with channels of limited length. The molecular sieve has a high silica to alumina ratio and has pores sized to limit production of aromatics in the cracking process. | 12-25-2008 |
| 20090197426 | Process for Preparing a Dielectric Interlayer Film Containing Silicon Beta Zeolite - A process for forming a zeolite beta dielectric layer onto a substrate such as a silicon wafer has been developed. The zeolite beta is characterized in that it has an aluminum concentration from about 0.1 to about 2.0 wt. %, and has crystallites from about 5 to about 40 nanometers. The process involves first dealuminating a starting zeolite beta, then preparing a slurry of the dealuminated zeolite beta followed by coating a substrate, e.g. silicon wafer with the slurry, heating to form a zeolite beta film and treating the zeolite beta with a silylating agent. | 08-06-2009 |
| 20100152025 | Molecular Sieve - The present invention comprises an improved MgMxAPSO-31 molecular sieve and a catalyst composite which demonstrates a favorable combination of conversion and selectivity in aromatics conversion. The sieve comprises a at least two divalent elements with narrow specific concentration limits in the framework structure having defined crystal characteristics. The element Mx may comprise one or more of manganese, cobalt, nickel, iron and zinc. | 06-17-2010 |
| 20100152511 | Hydrocarbon Conversion Using an Improved Molecular Sieve - The present invention comprises a hydrocarbon-conversion process using an improved MgAPSO-31 molecular sieve which demonstrates a favorable combination of conversion and selectivity in aromatics conversion. The sieve has a specific combination of crystal configuration, being limited in diameter and length, specified crystallinity as measured by an X-Ray Diffraction Index (XRDI), and a narrow range of magnesium content. | 06-17-2010 |
| 20100152512 | Hydrocarbon Conversion Using An Improved Molecular Sieve - The present invention comprises a hydrocarbon-conversion process using an improved MgMxAPSO-31 molecular sieve which demonstrates a favorable combination of conversion and selectivity in aromatics conversion. The sieve comprises at least two divalent elements with narrow specific concentration limits in the framework structure having defined crystal characteristics. The element Mx may comprise one or more of manganese, cobalt, nickel, iron and zinc. | 06-17-2010 |

| 20100105974 | Mixture of Catalysts for Cracking Naphtha to Olefins - A process is presented for the selective catalytic cracking of naphtha to light olefins. The process includes contacting a naphtha feedstream with a mixture of catalysts to reduce the amount of recycle, and especially the recycle of light paraffins. The mixture of catalysts includes a first molecular sieve made up from a small pore zeolite having a pore index between 13 and 26, and a second molecular sieve made up from an intermediate pore zeolite having a pore index between 26 and 30. | 04-29-2010 |

| 20100332501 | SYSTEM AND METHOD FOR ON-DEMAND INDEXING - A system and method for on-demand indexing in a data management system is described. An index is generated when it is requested, such as when a database operation requires access to the index. If the index is loaded in memory, the index is retrieved from memory. Otherwise, the index is generated on-demand. A priority configuration identifies at least one priority index which is generated and loaded in memory. The priority configuration can identify priority indexes either directly or indirectly, such as by a threshold parameter. | 12-30-2010 |

| 20110138025 | Systems and Methods for Extensible Distributed Configuration Management - Systems and methods for extensible distributed configuration management of computer resources are described. Examples include a computer system including a processing unit and a storage device that stores a model definition and one or more asset plug-ins (each of the one or more asset plug-ins configured to expose at least one asset object that represents a computer resource). The computer system further includes memory that stores an asset model created based at least in part on the model definition, and a network interface configured to deploy to at least one managed system a compatible asset plug-in (the model definition including at least one conditional reference to the compatible asset plug-in). If a condition specified within the asset model is satisfied the processing unit selects the compatible asset plug-in for deployment, the condition being defined within the model definition and designated as applicable to the at least one conditional reference. | 06-09-2011 |
