Patent number: 5639431Abstract: A hydrogen producing apparatus for producing hydrogen on an industrial scale by steam reforming reactions and separating hydrogen using a hydrogen-permeable membrane, including nested outer (14), intermediate (18) and inner (20) cylinders, a combustion burner (44) disposed toward the inner hollow chamber of the inner cylinder (20), a catalyst layer (A) in the annulus (30) between the intermediate (18) and inner (20) cylinders, hydrogen-permeable tubes (32) disposed in the catalyst layer (A-30), and sweep gas supply tubes (34) in the hydrogen-permeable tubes (32). The raw material gas is fed to the catalyst layer (A) and is converted into hydrogen at a high temperature produced by the burner (44), the produced hydrogen permeates the hydrogen-permeable tubes (32) which selectively separate and collect the hydrogen, and the permeated hydrogen flows with the sweep gas out of the apparatus through the outlet (52) for the sweep tubes (34).Type: GrantFiled: March 16, 1994Date of Patent: June 17, 1997Assignees: Tokyo Gas Co. Ltd., Mitsubishi Jukogyo Kabushiki KaishaInventors: Yoshinori Shirasaki, Masayuki Gondaira, Yoshu Ohta, Hiroshi Uchida, Kennosuke Kuroda, Toshiyuki Uchida, Yoshimasa Fujimoto, Hiroshi Makihara, Shinsuke Ohta, Kazuto Kobayashi

Patent number: 4603077Abstract: A water-absorbing laminate comprising a water-absorbing film and a non-woven fabric, in which the water-absorbing film is formed by film-forming a mixture of (A) a water-soluble polymer containing, as the monomer component, at least 40 mole % of an .alpha.,.beta.-unsaturated compound containing one or two carboxyl groups or groups from which a carboxyl group can be easily derived and in which 5% to 50% of the carboxyl groups and/or groups from which a carboxyl group can be easily derived are in the form of a salt, and (B) polyvinyl alcohol in a weight ratio of (A)/(B) of not less than 1/99 to less than 1/9. This water-absorbing can be produced by laminating the water-absorbing film on the non-woven fabric under pressure either in a hydrous and heat-softened state of the film or through an adhesive and, optionally, heat-treating the resultant laminate.Type: GrantFiled: April 2, 1985Date of Patent: July 29, 1986Assignees: Mitsui Petrochemical Industries, Ltd., Tokyo Serofan Co., Ltd.Inventors: Yoshimasa Fujimoto, Hirotoshi Miyazaki
