    摘要: A process for preparing ethylbenzene from benzene and ethylene in which a vapor phase alkylation reactor is combined with a liquid phase transalkylation reactor wherein the xylenes content of the ethylbenzene product is less than 700 wppm. Also disclosed are ethylbenzene processes in which a series-arranged or combined vapor phase alkylation/transalkylation reaction zone is retrofitted to have a vapor phase alkylation reactor and a liquid phase transalkylation reactor, and in which a parallel-arranged vapor phase alkylation reactor and vapor phase transalkylation reactor is retrofitted to have a vapor phase alkylation reactor and liquid phase transalkylation reactor. An apparatus for the practice of the ethylbenzene process of this invention is disclosed.

    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. After loading of the catalyst, the converted unit is operated as a fixed-bed unit by passing a C2- C4 olefinic feed and a light aromatic co-feed containing benzene to a fixed bed of the MWW zeolite catalyst to effect alkylation of the benzene with the aromatic co-feed, typically at a temperature from 150 to 350° C., a pressure not greater than 7000 kpa, usually less than 4000 kPa and an olefin space velocity up to 10 WHSV.

    摘要: A torsion damper, especially for a motor vehicle clutch, is of the kind which includes a friction cassette, i.e. a unitary sub-assembly comprising a friction assembly, which includes a guide ring, a spacing ring having at its outer periphery at least one axially oriented projection, at least one drive ring interposed axially between the guide ring and the spacing ring. A spring causes the drive ring to be gripped between the guide ring and the spacing ring, and this spring bears on a closing ring which is arranged on the side of the guide ring opposite to the spacing ring, and the closing ring is connected to the axial projection of the spacing ring.

    摘要: An encapsulated refrigerator shelf is assembled by interconnecting a platform, such as a glass panel, within a peripheral frame. More specifically, a peripheral shelf frame is formed with a split side portion defining upper and lower frame portions which are spaced by an elongated slot. The encapsulated glass refrigerator shelf is made by slidably inserting the platform onto peripheral frame support structure through the slot formed between the upper and lower frame portions. The frame is also formed with retaining structure to maintain the platform in place once the platform is inserted a requisite amount within the peripheral frame.

    摘要: The disclosed clutch comprises a wear take-up device (2, 4) that includes elastic compensating elements (2), operating axially between the support (1) and the response clutch plate (3). The system further comprises a blocking mechanism (41) operated by a release (41) to allow movement of the response plate to accommodate for wear. Said compensating elements (2) exert a force greater than that of the shifter elements of the clutch.
