  • Publication number: 20050013754
    Abstract: An apparatus for producing hydrogen by a steam reforming reaction, on a catalyst, of a hydrocarbon or an oxygen-containing hydrocarbon as a raw material is disclosed. The apparatus comprises a hydrogen separation type reformer which has a means for heating the catalyst and which has a hydrogen separation membrane built into a layer of the catalyst for selectively separating hydrogen; a cooling means for cooling high temperature high purity hydrogen obtained from the reformer; and a hydrogen storage/delivery means disposed downstream from the cooling means and composed of a hydrogen occluding material.

  • Patent number: 5639431
    Abstract: 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).

  • Patent number: 4747001
    Abstract: A device which is compatible for selectively loading either a first disk cartridge in which a first disk is encased or a second disk cartridge in which a second disk is encased and wherein the radius of the first disk is different from the radius of the second disk, the first cartridge having a first width extending over substantially the whole length of the first cartridge in the intended direction of cartridge insertion, the second cartridge consisting of a front portion having a width equal to the first width and a rear portion having a width greater than the first width, the device including a chassis and a cartridge guiding and loading apparatus supported by the chassis for selectively loading either the first cartridge or the second cartridge, the cartridge guiding and loading apparatus including guides for guiding either the first or the second cartridge as the first or second cartridge is selectively loaded into the device, the guides being moveable between first and second positions such that when in

  • Patent number: 4603077
    Abstract: 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.
