Patent JP-4177909-B2 (JP)
IPC: C07B61/00
Filed: 1997-10-30
Granted: 2008-11-05
Abstract: The present invention addresses heat integration in an alkylation/transalkylation process involving alkylation of an aromatic substrate with a C2-C4 alkylating agent coupled with separation to recover a monoalkylated aromatic product and liquid phase transalkylation of a polyalkylated product. Aromatic feedstock and a C2-C4 alkylating agent are supplied to an alkylation reaction zone which is operated to produce an alkylated product. The output from the alkylation reaction zone initially travels through an arrangement of heat exchangers. From there, the alkylation effluent passes into the first separation zone which is operated to produce a lower boiling fraction comprising the aromatic substrate, which may be recycled to the alkylation reaction zone, and a higher boiling fraction comprising a mixture of monoalkylated and polyalkylated aromatics. This lower boiling fraction first travels back through portions of the heat exchanger arrangement on the way to recycle into the alkylation zone. The higher boiling fraction of the first separation zone is supplied to a secondary separation zone to produce a second lower boiling fraction comprising the desired monoalkylated product and a higher boiling fraction comprising polyalkylated product. At least a portion of the higher boiling polyalkylated fraction passes through a portion of the heat exchanger arrangement into a transalkylation reaction zone containing a molecular sieve transalkylation catalyst operated under liquid phase conditions to cause disproportionation of the polyalkylated fraction to arrive at a disproportionation product having a reduced polyalkylated aromatic content and an enhanced monoalkylated aromatic content.

Abstract: A machine for feeding beverage cans to open-ended carrier sleeves of varying capacities. When loading relatively small carrier sleeves, inboard conveyors and associated metering screws feed groups of cans to a flight bar conveyor which moves the groups through the open ends of the carrier sleeves. When loading relatively large carrier sleeves, outboard conveyors and associated metering screws are also operated after first replacing the inboard screws with screws able to separate cans into larger groups, the same size as those formed by the outboard screws. This arrangement feeds larger groups of cans which are then fed to the larger carrier sleeves. In one embodiment each conveyor comprises a longer upstream conveyor and a shorter downstream conveyor spaced a short distance therefrom to allow the flight bars to travel through the space between the conveyors when moving from the end of their upward run to the beginning of their horizontal downstream run. In another embodiment only the longer upstream conveyor is provided and a support plate is used instead of the downstream conveyor. In this embodiment the gap between the conveyor and the plate is automatically closed by a shuttle mechanism to provide a continuous support surface for the cans as they are pushed toward the carrier sleeves. The cans are able to slide on the surface of the conveyors, enabling the conveyors to be operated at a slightly greater speed than the screws are capable of moving the cans, which results in the cans being positively fed by the conveyors.
