Patent number: 8394181Abstract: A permselective material has a polymer having an organosiloxane skeleton and containing a dispersed solid additive. When oxygen and nitrogen are passed through a membrane having the permselective material, the relation between the permeability coefficients [cm3·cm·sec?1·cm?2·cmHg?1] of oxygen and nitrogen at a temperature of 23±2° C. under a pressure difference of 1.05 atm to 1.20 atm through the membrane is expressed by Formula (1): 0.94 ? P ? ( O 2 ) P ? ( N 2 ) < 1 ( 1 ) where P(O2) denotes the permeability coefficient of oxygen, while P(N2) denotes the permeability coefficient of nitrogen.Type: GrantFiled: December 26, 2007Date of Patent: March 12, 2013Assignees: Shin-Etsu Polymer Co., Ltd., DENSO CORPORATION, Shin-Etsu Chemical Co., Ltd.Inventors: Junya Ishida, Katsunori Iwase, Akira Yamamoto, Masahiko Minemura

Patent number: 7763214Abstract: A reforming device includes a reforming part that subjects a hydrocarbon-based raw material to be reformed to a reforming reaction to form a reducing agent to be supplied to a reducing catalyst for reducing nitrogen oxide selectively. The reforming part has a reforming reaction region through which the raw material to be reformed passes and is reacted with supplied hydrogen atoms supplied so as to be reformed to the reducing agent. For example, a hydrogen permeable membrane having a first surface and a second surface may be provided in the reforming part to permeate hydrogen atoms from the first surface to the second surface and to produce the hydrogen atoms on the second surface. The reforming device can be suitably used for an exhaust gas control system for cleaning exhaust gas, for example.Type: GrantFiled: September 25, 2006Date of Patent: July 27, 2010Assignee: Denso CorporationInventors: Katsunori Iwase, Tetsuo Toyama, Shigeru Ooyanagi, Yoshiaki Nishijima, Masahiro Okajima
