Definitions

  • the invention relates to a membrane reactor with a housing penetrating, a catalyst receiving flow channel for a process gas and with a flow path for a permeate, which is separated from the flow channel for the process gas by a permeate membrane.
  • methanol which has a high energy density and unlimited storage without losses, be used as a liquid, easily manageable hydrogen storage device.
  • a vaporized methanol-water mixture is converted as a process gas in a catalytic reaction essentially into hydrogen and carbon dioxide, the hydrogen being the main component of the permeate and the carbon monoxide being the main component of the retentate.
  • the process gas which is essentially made up of methanol and water, is passed through a tubular duct equipped with a catalyst, the jacket of which serves as a porous support for the membrane.
  • the permeate formed by the hydrogen penetrating the membrane is withdrawn in countercurrent to the process gas through the annular gap between the pipe channel and the reactor housing enclosing the pipe channel at a distance.
  • the invention is therefore based on the object of designing a membrane reactor in such a way that over the entire local and temporal course of the reaction, favorable parameters for the catalytic conversion of a process gas into a permeate, in particular for the production of hydrogen from methanol, can be guaranteed.
  • the invention solves the problem in that the housing is composed of individual housing modules that form the flow channel for the process gas that runs from housing module to housing module and that are connected to a collecting line for the permeate, transversely have hollow bodies aligned with the flow channel as a carrier for the membrane.
  • housing modules form housing rings which are flanged together between two end caps provided on the one hand with an inlet for the process gas and on the other hand with an outlet for the retentate, so that between the two end caps they differ in their structure and number Housing modules can be combined into a membrane reactor adapted to the respective requirements.
  • the individual housing rings can be sealed against one another in a simple manner with the aid of ring seals.
  • housing modules for permeate discharge on the flow inlet side can be provided with appropriate catalysts, there are advantages in terms of freedom of design if the catalyst and the hollow body provided with the membrane are provided in separate housing modules.
  • the aligned transversely to the flow channel, enclosed with a membrane for Permeatab conduction hollow bodies can be formed in a simple manner from porous tubes which open into collecting spaces provided on the outside of the housing modules and connected to the collecting line. With the number and the diameter of these tubes carrying the membrane, the ratio of the membrane area to the cross section of the flow channel for the process gas or the reaction gas can easily be determined.
  • At least one housing module can have a heat exchanger.
  • heat exchanger modules heat can both be supplied and removed as required in order to be able to set the most favorable process temperature in each case.
  • Show it 1 shows a membrane reactor according to the invention in a schematic longitudinal section
  • FIGS. 1 and 2 shows a section along the line II-II in FIGS. 1 and
  • FIG. 3 shows an embodiment variant of a membrane reactor according to the invention in a schematic section corresponding to FIG. 1.
  • a membrane reactor according to the invention has a housing 1, which is composed of individual, preferably housing rings forming housing modules 2, 3 and 4, which are flanged together sealingly between two end caps 5, 6.
  • the flanged housing modules 2, 3 and 4 form a continuous flow channel 7, which is exposed to a process gas 9 through an inlet 8 of the end cap 5 and opens into an outlet 10 for the retentate 11 in the area of the opposite end cap 6.
  • the housing modules 2 have hollow bodies 12 running transversely to the flow channel 7 in the form of porous tubes as supports for a membrane 13. These hollow bodies 12 open into a collecting space 16 provided on the outside of the housing modules 2 and connected to a collecting line 14 for the permeate 15.
  • the housing modules 2 for permeate discharge are provided in the flow direction of the process gas 9 with a catalyst 17 housing modules 3 vorgela.
  • the catalytic conversion of the process gas 9 into a permeate 15 and a retentate 11 takes place.
  • the permeate that forms is deposited in the respective subsequent housing module 2 via the membrane 13 and discharged through the hollow body 12.
  • the process gas portion is catalytically converted again in a subsequent flow section in order to be able to remove a largely process gas-free retentate 11 from the membrane reactor after a multistage catalytic conversion with subsequent permeate discharge.
  • the influence of temperature on the catalytic reaction can be taken into account by housing modules 4 which accommodate a heat exchanger 18, for example in the form of coiled tubes for a heat carrier, with the help of which heat can either be introduced or removed as required.
  • a membrane reactor according to FIG. 1 is charged with a methanol-water vapor mixture as process gas 9 for hydrogen production, a partially catalytic conversion of the process gas 9 into the main components carbon dioxide and hydrogen takes place first in a housing module 3, which in the following housing module 2 via the Membrane 13 is derived through the hollow body 12.
  • the remaining reaction gas from process gas enriched with carbon dioxide is heated to a process temperature favorable for the subsequent catalytic reaction by supplying heat in the subsequent heat exchanger 18 of a housing module 4 in order to be able to divert the hydrogen converted from the process gas into a housing module 2.
  • the hydrogen deposited in the individual housing modules 2 is drawn off for further use through a collecting line 14 common to these housing modules 2.
  • FIG. 3 shows a membrane reactor whose inlet side catalyst section has been extended compared to the exemplary embodiment according to FIG. 1 by connecting two housing modules 3 accommodating a catalyst 17 in series.
  • the process temperature in this extended catalyst section is influenced by an upstream heat exchanger 18 of a housing module 4.
  • the subsequent implementation of the process gas remaining in the reaction gas is optimized according to FIG.
  • the modular structure of the membrane reactor can be optimally adapted to different requirements of the conversion and separation processes, because the arrangement and properties of catalysts, heat exchangers and membranes can be changed as required and to the respective reaction as well as initially unknown boundary conditions and component properties can be coordinated so that all housing modules can work in an optimal range of the parameters relevant for the conversion.
