摘要:
A gas stream containing nitrous oxide and ammonia is contacted with a catalyst composition containing a zeolite. N2O is reduced to N2 and H2O at low temperatures in a highly efficient manner. Ammonia-mediated reduction of nitrous oxide can be effectuated from gas streams having N2O concentrations as low as 1%. The gas stream may also contact a catalytic composition selective for the reduction of NOx. In this way, N2O and NOx treatment may be effectuated in a single process stream.

The invention pertains to a layered ammonia oxidation catalyst. The layered catalyst causes ammonia to be selectively oxidized in the presence of an oxidant such as air, while minimizing the formation of nitrogen oxides (NOx). The layered catalyst comprises a refractory oxide support such as gamma alumina upon which a platinum component is deposited and a vanadia component is deposited on the platinum. The catalyst is preferably disposed on a substrate such as a metal foil whose surface contains a “herringbone” pattern.

The present invention is directed to an iron-promoted zeolite beta catalyst useful in the selective catalytic reduction of nitrogen oxides with ammonia in which the iron-promoted zeolite beta is treated so as to provide increased amounts of the iron promoter in the form of Fe(OH). The stabilized zeolite is formed by cation exchange of an iron salt into a zeolite beta which has a reduced sodium content such as by exchanging a sodium beta with ammonium or hydrogen cations. A zeolite beta having a reduced carbon content and a Si/Al ratio of no more than 10 also increases the Fe(OH) content of the iron-promoted catalyst. The iron-promoted catalyst which has the iron in the form of Fe(OH) is characterized by a peak at 3680±5 cm−1 in the IR spectra.

An active network system for a host device with a host processor, comprises a wireless port including a first physical layer/medium access control (PHY/MAC) device. A first wired port includes a second PHY/MAC device. A secondary processor communicates with the wireless port, the first wired port and the host processor. The secondary processor, the wireless port and the first wired port support network functionality when the host processor is an inactive mode. The network functionality includes at least one of access point functionality, router functionality, repeater functionality, point-to-point functionality and point-to-multipoint functionality.

A method and system for automatically analyzing graphics processing unit (“GPU”) test results are disclosed. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of identifying the GPU test results associated with a first register type, creating a template document associated with the same first register type, wherein the template document is pre-configured to store and operate on the GPU test results of the first register type, filling the GPU test results in the template document, aggregating the GPU test results associated with the first register type to establish a common output, and determining a suitable register value from a passing range of register values based on the common output without human intervention.

A mediation server (30) includes a second request receiving unit (35) that receives first store information for identifying a store visited by a user as a visited store and second store information for identifying a designated store designated as a place to purchase an item recognized by the user at the visited store from a mobile terminal (10) of the user, a response information generating unit (36) that compares the first and second store information and determines whether the visited store and the designated store match, and generates bargaining information indicating a specified service offered for the item by the visited store when the two stores do not match, and a response information transmission unit (37) that transmits the generated bargaining information to the mobile terminal (10).
摘要:
A system for the accelerated re-provisioning of data over cable service interface specification (DOCSIS) configuration files between a DOCSIS provisioning server and a plurality of network nodes that are configured according to the DOCSIS configuration files is provided. The system includes: a memory; and a caching entity configured to monitor transmissions from the provisioning server of the configuration files to the network nodes so as to both store the configurations files in the memory and to pass-through the configuration files to the network nodes; the caching entity being further configured to monitor requests to the provisioning server for respective ones of the DOCSIS configuration files from the network nodes, the caching entity being further configured to determine for each of the requests whether the requested configuration file has been previously requested node such that if the caching entity determines that the requested configuration file has been previously requested the caching entity retrieves the previously requested configuration file from the memory and returns the retrieved-from-memory configuration file to the network node.
