    摘要: A process is described for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene and one or more alkanes are introduced into said first alkylation reaction zone. The first alkylation reaction zone is operated under conditions of temperature and pressure effective to cause alkylation of the aromatic compound with the alkene in the presence of the alkylation catalyst, the temperature and pressure being such that the aromatic compound is partly in the vapor phase and partly in the liquid phase. An effluent comprising the alkylaromatic compound, unreacted alkylatable aromatic compound, any unreacted alkene and the alkane is withdrawn from the first alkylation reaction zone and then supplied to the second alkylation reaction zone without removal of the alkane. The operating conditions in each of said first and second reaction zones are such that the ratio of the volume of liquid to the volume of vapor in each zone is from about 0.1 to about 10.

    摘要: A grounding assembly for sunken placement in a surface includes a housing for sunken placement in a surface. A top plate covers the interior space of the housing. The top plate defines an opening, and a hinging access panel when closed prevents access to the interior space of the housing by covering the opening. At least one grounded cable stored within the interior space of the housing can be deployed through the opening of the top plate. A strut spans the opening of the top plate and supports the access panel when in the closed configuration. An electrical contact such as a clamp is connected to a free end of the grounded cable for grounding an aircraft or other vehicle or equipment.

    摘要: A data processing device employs a first translation look-aside buffer (TLB) to translate virtual addresses to physical addresses. If a virtual address to be translated is not located in the first TLB, the physical address is requested from a set of page tables. When the data processing device is in a hypervisor mode, a second TLB is accessed in response to the request to access the page tables. If the virtual address is located in the second TLB, the hypervisor page tables are bypassed and the second TLB provides a physical address or information to access another table in the set of page tables. By bypassing the hypervisor page tables, the time to translate an address in the hypervisor mode is reduced, thereby improving the efficiency of the data processing device.

    摘要: Solid phosphoric acid (SPA) olefin oligomerization process units may be converted to operation with a more environmentally favorable solid catalyst. The SPA units in which a light olefin feed is oligomerized to form gasoline boiling range hydrocarbon product, is converted unit to operation with a molecular sieve based olefin oligomerization catalyst comprising an MWW zeolite material. Besides being more environmentally favorable in use, the MWW based zeolites offer advantages in catalyst cycle life, selectivity and product quality. After loading of the catalyst, the converted unit is operated as a fixed-bed unit by passing the C2-C4 olefinic feed to a fixed bed of the MWW zeolite condensation catalyst, typically at a temperature from 150 to 250° C., a pressure not greater than 7000 kPag, usually less than 4000 kPag and a space velocity up to 30 WHSV. The gasoline boiling range product is notable for a high level of branched chain octenes resulting in high octane quality.

    摘要: A process for the production of high octane number gasoline from light refinery olefins, typically from the catalytic cracking unit, and benzene-containing aromatic streams such as reformate. A portion of the light olefins including ethylene and propylene is polymerized to form a gasoline boiling range product and another portion is used to alkylate the light aromatic stream. The alkylation step may be carried out in successive stages with an initial low temperature stage using a catalyst comprising an MWW zeolite followed by a higher temperature stage using a catalyst comprising an intermediate pore size zeolite such as ZSM-5. Using this staged approach, the alkylation may be carried out in the vapor phase. Alternatively, the alkylation may be carried out in the liquid phase using the heavier olefins (propylene, butene) dissolved into the aromatic stream by selective countercurrent extraction; a separate alkylation step using the ethylene not taken up in the extraction is carried out at a higher temperature.
