Abstract:
The method serves for producing a horizontal through flow adsorber with two adsorbents which contains two immediately adjacent packings in a horizontal or vertical container. Between the two packings there is a vertical interface. In a step (a) a vertical dividing wall is positioned on the bottom of the adsorption bed and then on each side of the dividing wall one of the two adsorbents is charged up to a first height that does not exceed the upper edge of the separating ring. In the following step (b) the vertical dividing wall is displaced upwardly until the lower edge thereof is still placed in the existing packing. Then, on each side of the dividing wall one of the two adsorbents is charged up to a second height that does not exceed the upper edge of the displaced dividing wall. Finally, step (b) is repeated until a predetermined filling height is achieved. According to the invention, the vertical dividing wall is composed of at least three dividing wall modules (6.01) that extend only over a part of the length or of the periphery of the vertical dividing wall and are movable in a vertical direction independently of one another.
Abstract:
In order to provide a chemical reaction apparatus that can suppress a situation where microwaves are concentrated on a partial portion in a reactor, and that can more uniformly irradiate a content with the microwaves, a chemical reaction apparatus includes: a horizontal flow-type reactor in which a liquid content horizontally flows with an unfilled space being provided thereabove; a microwave generator that generates microwaves; and a waveguide that transmits the microwaves generated by the microwave generator to the unfilled space in the reactor, wherein a top of the reactor is curved with respect to a flow direction of the content.

Abstract:
A body (50) of a hydrogen generator of the present invention includes a reformer (10) configured to generate a reformed gas mainly containing hydrogen, a reforming material passage (1) configured to supply a reforming material, which is a material for a reforming reaction, to the reformer, a CO shifter (15) configured to convert CO contained in a reformed gas obtained from the reformer (10) into CO2, a reformed gas passage (2) configured to supply the reformed gas obtained from the reformer (10) to the CO shifter (15), and a passage (3) for the shifted gas obtained from the CO shifter (15). The shifted gas passage (3) and the reforming material passage (1) are adjacent to each other with a shared horizontal wall (31) interposed therebetween, and thereby, heat from the shifted gas and radiant heat from the downstream end face (15b) of the CO shifter are transferred to the reforming material that travels in the reforming material passage (1).
Abstract:
A gas generation system for providing a gas flow to be supplied to a reformer includes an evaporator for evaporating the components contained in a gas flow, wherein the gas flow includes at least one carbon compound, such as hydrocarbon or alcohol, and water vapor. A normalizing stage is connected between the evaporator and the reformer for equalizing the temperature distribution in the gas flow to be supplied to the reformer. The temperature of the gas flow should be equalized to a temperature range below the maximum allowable reformer inlet temperature. In this way, temperature maxima caused by a load change are equalized, thereby significantly increasing the service life of the reformer catalyst.
Abstract:
An evaporator arrangement and/or vaporizing burner is provided for generating a hydrocarbon vapor/mixed material mixture. The arrangement has a mixing chamber (50) surrounded by a circumferential wall area (46) and a bottom wall area (44). Inlet openings (48) are provided in the circumferential wall area (46) for the entry of gaseous mixed material into the mixing chamber (50) and the bottom wall area (44) has a porous evaporator medium (62) for absorbing liquid hydrocarbon. A first heating device (76) is associated with the porous evaporator medium (62). A second heating device (94) heats the mixed material before or/and during its passage through the inlet openings (48).
Abstract:
A reactor arrangement and process for indirectly contacting a reactant stream with a heat exchange stream uses an arrangement of heat exchange plates to control temperature conditions by varying the heat transfer factor in different portions of a continuous channel defined by the heat exchange plates. The reactor arrangement and process of this invention may be used to operate a reactor under isothermal or other controlled temperature conditions. The variation in the heat transfer factor within a single heat exchange section is highly useful in maintaining a desired temperature profile in an arrangement having a cross-flow of heat exchange medium relative to reactants. The corrugations arrangement eliminates or minimizes the typical step-wise approach to isothermal conditions.
Abstract:
A unitary, multiple-stage reaction system for countercurrently contacting a fluid reactant stream with catalyst particles movable through the system via gravity-flow. The reaction zones, or stages, are vertically stacked in a single chamber wherein catalyst particles flow from one annular-form bed to the next lower annular-form bed. A first portion of the hydrocarbonaceous charge stock flows downwardly into the lowermost reaction zone, laterally (outward to inward flow) through the annular-form catalyst bed into a center reactant conduit, is admixed with the second portion of the charge stock, flows upwardly through the reactant conduit into the next upper zone and laterally (inward to outward flow) through the annular-form catalyst bed. A preferred embodiment involves three reaction zones within the reaction chamber, with heat-exchange provisions between the middle and upper zones.
