Publication number: 20090256305Abstract: In a feeding device, a first friction pad and a second friction pad are disposed on a circumferential surface of a pick roller so that a first contact area and a second contact area overlap each other. Thus, to a conveyance-target medium, which is either one of a conveyed medium and a separation-target medium, pressing forces are successively applied by the first friction pad or the second friction pad over the first contact area to the second contact area. Therefore, the conveyance-target medium, which is either one of the conveyed medium and the separation-target medium, successively receives a separation force in a total contact area wider than an area when receiving a separation force only in either one of the first contact area and the second contact area. With this, the capability of separating the conveyed medium and the separation-target medium can be increased.Type: ApplicationFiled: October 10, 2008Publication date: October 15, 2009Applicant: PFU LIMITEDInventors: Shuichi MORIKAWA, Masao TAKAYAMA, Hideyuki OKUMURA

Patent number: 6710003Abstract: A layered catalyst composition is disclosed where the composition is prepared by bonding an outer layer comprising a bound zeolite (e.g. zeolite beta) to an inner core material (e.g. cordierite). The use of an organic bonding agent in the catalyst preparation procedure provides a composition that is sufficiently resistant to mechanical attrition to be used commercially in aromatic alkylation processes (e.g. benzene alkylation to ethylbenzene). Advantages associated with the use of layered compositions include a significant reduction in the amount of zeolite used for a given reactor loading and improved selectivity to desired alkylated aromatic products. Further benefits are realized when the layered composition is formed into shapes having a sufficiently high void volume to reduce pressure drop across the alkylation catalyst bed. This is especially relevant for operation involving high recycle rates and consequently low alkylating agent concentrations in the reaction zone.Type: GrantFiled: December 13, 2001Date of Patent: March 23, 2004Assignee: UOP LLCInventors: Deng-Yang Jan, James F.
