    Abstract: A material is presented that exhibits excellent corrosion resistance to supercritical ammonia and is suitable for a supercritical ammonia reactor. An Ni-based corrosion resistant alloy includes from 15% or more to 50% or less by mass of Cr and any one or both of Mo and W, wherein a [(content of Mo)+0.5×(content of W)] is from 1.5% or more to 8.5% or less by mass, a value of 1.8×[% content of Cr]/{[% content of Mo]+0.5×[% content of W]} is from 3.0 or more to 70.0 or less and the balance is Ni and an unavoidable impurity. The alloy may be used to configure a supercritical ammonia reactor or the material is coated on a surface that contacts with a supercritical ammonia fluid. The alloy exhibits excellent corrosion resistance to supercritical ammonia and a mineralizer added the supercritical ammonia. The safety and reliability of an apparatus can be improved, the producing cost can be reduced, the apparatus lifetime can be extended and the running cost can be reduced.

    Abstract: To provide an apparatus for producing silicon capable of recovering silicon sufficiently in a recovery container even if the silicon deposited in a reaction container solidifies in the shape of an anthill.[Means for Solution] The apparatus for producing silicon has means for moving a recovery container 14 in a reaction container body 2. The moving means includes a support shaft 18 for supporting a bottom wall 14b of the recovery container 14 and a drive unit 17 for rotating the support shaft 18, which are provided for the recovery container 14. The support shaft 18 is deviated from the position of the center portion of the opening 7a on the lower end side of the reaction tube 7 so that the support shaft 18 suitably rotates at the time when the silicon is recovered in the recovery container 14 thereby varying the position on where the anthill is formed.

    Abstract: A fuel gas-steam reformer assembly, preferably an autothermal reformer assembly, for use in a fuel cell power plant, includes a mixing station for intermixing a relatively high molecular weight fuel and an air-steam stream so as to form a homogeneous fuel-air-steam mixture for admission into a catalyst bed. The catalyst bed includes catalyzed alumina pellets, or a monolith such as a foam or honeycomb body which is preferably formed from a high temperature material such as a steel alloy, or from a ceramic material. The catalyst bed is contained in a shell which is preferably formed from stainless steel or some other high temperature alloy. The shell includes an internal peripheral thermal insulation layer of zirconia (ZrO2), either in a felt form, or in a rigidified foam. The zirconia insulation layer provides thermal insulation for the shell and retains heat in the catalyst bed and protects the shell against thermal degradation from the hot catalyst bed; and it also protects the catalyst bed against carbon deposition from the fuel and oxygen mixture flowing through the catalyst bed. The use of an internal zirconia insulation layer obviates the need to provide an alumina washcoat and metal oxide coatings on the inner surface of the shell for inhibiting carbon deposition in the catalyst bed. The zirconia insulation layer is non-acidic and possesses carbon gasification properties which are similar to the carbon gasification properties possessed by calcium and alkali metal oxides. Unlike silica insulation, zirconia insulation does not vaporize in the presence of high temperature steam.
