Title: Production of hydrocarbons
Inventor: ABBOTT PETER EDWARD JAMES
IPC: C01B3/38
Filed: 2003-10-23
Abstract: A process for the production of hydrocarbons is described comprising a) subjecting a hydrocarbon feedstock (10) to steam reforming by dividing the feedstock into first (12) and second (13) streams, mixing the first stream with steam (16), passing the mixture of the first stream and steam over a catalyst disposed in heated tubes in a heat exchange reformer (28) to form a primary reformed gas (30), forming a secondary reformer feed stream (40) comprising the primary reformed gas and the second hydrocarbon stream, partially combusting the secondary reformer feed stream with an oxygen- containing gas (44) and bringing the resultant partially combusted gas towar ds equilibrium over a secondary reforming catalyst, and using the resultant secondary reformed gas (48) to heat the tubes of the heat exchange reformer, thereby producing a partially cooled reformed gas, b) further cooling the partially cooled reformed gas to below the dew point of the steam therein to condense water and separating condensed water (56) to give a de-watered synthesis gas (58), c) synthesising hydrocarbons from said de-watered synthesis gas by the Fischer-Tropsch reaction and separating at least some o f the synthesised hydrocarbons, to give a tail gas (70), and d) incorporating at least part of said tail gas into the secondary reformer feed stream before t he partial combustion of thereof.

La localisation est basée sur la pluralité de séries de trames vidéo reçues.
Patent CA-2506974-A1 (CA)
Inventor: SONI DALIP S
IPC: C10G11/18
Filed: 2003-11-18
Abstract: An apparatus (200) for the countercurrent contacting of a gas and downflowing solid particles includes a housing (205) and a plurality of baffles (100) positioned within the housing. The baffles are arranged in at least first and second vertically spaced levels in successively lower position, each of the first and second levels including a row of at least two baffles oriented parallel to one another and inclined from horizontal so as to facilitate movement of the solid particles and provide the maximum area for flow. Baffles are oriented so as to laterally shift the direction of downflowing particles transversely as the particles move from one level to the next lower level and avoid channeling of the phases. The number of baffles, length and spacing is optimized to provide maximum interfacial area for interaction between the phases.

Abstract: A window shade comprising a plurality of collapsible shade rows. Each of the shade rows being adjustable from a closed state to an opened state by an operating mechanism, and including a stiff first transverse region and an opposed second transverse region having a stiffened edge portion. When in the closed state, the window covering includes no or minimal gaps between the rows so that light is substantially or completely blocked. Also, the securement and opening members are also concealed from view when observed from the front or face of the window covering. The operating mechanism causes the narrowing of the rows by drawing the first transverse region and the opposed second transverse region closer together. The operating mechanism further causes the rows to be pivotally rotated to further widen opening in the window covering.

Title: Trailer operable in lowered and raised transport positions
Inventor: TRUDEAU CLAUDE
IPC: B62D63/06
Filed: 2005-09-01
Abstract: A trailer includes a deck frame which can be supported in a lowered transport position in which the deck frame is spaced above the ground below a height of the wheels corresponding to a deck between configuration and a raised transport position in which the deck frame is spaced above the ground substantially at or above the height of the wheels corresponding to a deck over configuration. Consumers are thus only required to purchase a single trailer to meet the advantages of both trailer configurations. Load supports, independent of a lift mechanism of the trailer, are provided in addition to the linkage which controls displacement of the deck frame between the two positions to ensure that the deck frame is supported on the wheels in a manner so as to safely bear a load on the deck frame in both the lowered and raised positions.
