Abstract
A self-heating catalytic reforming reactor has a sleeve pipe structure consisting of an external pipe with a heat insulating and an internal pipe. The metallic foams as the catalyst carrier are filled in said internal tube and the space between said two pipes. Under the action of catalyst, the fuel is burning in the ring cavity to supply the heat needed by catalytic reforming reaction. A plasma technique is used for protecting the catalyst layer and preventing the metallic supporting layer from being corroded by other media.
Description
Technical field
The present invention relates to a kind of reactor that industrial equipment has chemical reaction to take place that is used for, especially under catalyst action, realize a kind of metal foam catalytic reforming reactor of heat release and heat absorption.
Background technology
Proton Exchange Membrane Fuel Cells (PEMFC) is a kind of TRT that utilizes Hydrogen Energy, as the generation technology of a new generation, with its distinctive high efficiency and environmental friendliness characteristic and caused global concern.
It is low that its prime advantage is embodied in operating temperature, is suitable for the occasion than frequent starting, has the advantages such as power density higher than the fuel cell of other type.It both can be used as stationary electric power plant, can be used as the power supply of destination again.Particularly in recent years, because the environmental pollution that traditional generation technology and automobile cause is serious day by day, fossil energy was petered out, and PEMFC is widely regarded as the best power source source of following automobile with its excellent technical performance and the polluting property lower to environment.
Summary of the invention
In order to reduce heat loss, reduce discharging, the objective of the invention is to, a kind of metal foam catalytic reforming reactor is provided.
Studies show that adopting the organic-fuel catalytic reforming to produce hydrogen is one of optimal selection to be used for PEMFC in the following long period, it can utilize existing infrastructure to carry out the catalytically reforming hydrogen producing of organic-fuel.Therefore, metal foam self-heating catalytic reforming reactor has broad application prospects.
The technical scheme that realizes the object of the invention solves like this:
A kind of metal foam catalytic reforming reactor comprises outer tube and interior pipe, and heat insulation layer is arranged on the outer tube, it is characterized in that, described outer tube and interior pipe adopt sleeve structure, fill up the metal foam as catalyst carrier in the interior pipe, also are filled with metal foam between interior pipe and the outer tube.
Two kinds of metal foam structures and material can be identical also can be different.
The present invention adopts metal foam as catalyst carrier.Though metal foam is a kind of porous media material, because characteristics such as its distinctive microcosmic supporting structure, high porosity (＞90%), specific area are big, flow resistance is less relatively make it be different from traditional porous media (as packed particle).Adopt metal foaming material as catalyst carrier and be filled in the reaction channel, can greatly increase the contact area and the heat transfer efficiency of reactant and catalyst, improve catalytic reaction efficient greatly.
This reactor has adopted the plasma spray coating technology.In combustion reaction one side, the using plasma technology has covered one deck combustion catalyst layer on the top layer of metal foam, catalytic reforming reaction one side then the using plasma technology adhere to one deck reforming catalyst at the corresponding metal foam surface.Like this, can make catalyst in the environment of high-temperature, still have high viscosity and high mechanical properties, thereby make it durable in use.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present invention
Fig. 2 is the schematic diagram of another kind of version of the present invention.
The invention will be further described below in conjunction with accompanying drawing and by preferred embodiment.
The specific embodiment
Metal foam catalytic reforming reactor of the present invention can be realized the efficient utilization to chemical reaction heat.Its structure as shown in Figure 1, it is a kind of catalytic reaction heat exchanger, comprises outer tube and interior pipe, heat insulation layer is arranged on the outer tube, outer tube and interior pipe adopt sleeve structure, fill up the metal foam as catalyst carrier in the interior pipe, also are filled with metal foam between interior pipe and the outer tube.Fuel under the effect of catalyst in annular chamber catalytic combustion, pipe catalytic reforming process required heat in liberated heat can pass to immediately, the operation principle of Here it is catalytic reaction heat exchanger.
Reactor environmental friendliness of the present invention.Along with the continuous breakthrough technically of this eco-friendly generation mode of fuel cell, obtained development rapidly such as many other chemical hydrogen producing technologies such as biomass hydrogen preparation, metal replacement hydrogen manufacturing, solar hydrogen making, metal hydride hydrogen manufacturing, and will be accompanied by the development and the application of technology such as fuel cell, hydrogen-fuel engine, together step into hydrogen energy era.And this efficient metal foam self-heating catalytic reforming reactor can be realized efficient hydrogen manufacturing, and greatly reduces the discharging of pollutant, has guaranteed cleaning, the close friend of environment.
Version of the present invention comprises outer tube of pipe in, outer tube of perhaps a plurality of interior pipes, and the shape of outer tube can be circular, square or other shapes are as long as form the category that the encirclement of internal pipe all belongs to sleeve structure of the present invention.
Self-heating catalytic reforming process with methyl alcohol is an example:
Wherein the steam reformation process is:
Catalyticing combustion process is:
The combination of these two processes can realize by a kind of close-coupled catalytic reaction heat exchanger.If the contact area of augmenting response thing and catalyst can significantly improve hydrogen generation efficiency so, reduce heat loss and discharging.
Metal foaming material provides the possibility that designs this efficient catalytic reactor.Though metal foam is a kind of porous media material, because characteristics such as its distinctive microcosmic supporting structure, high porosity (＞90%), specific area are big, flow resistance is less relatively make it be different from traditional porous media (as packed particle).Adopt metal foaming material as catalyst carrier and be filled in the reaction channel, can greatly increase the contact area and the heat transfer efficiency of reactant and catalyst, improve catalytic reaction efficient greatly.
Utilize the plasma spray coating technology to solve the problem of catalyst layer stickiness and mechanical strength deficiency under the high-temperature condition.In combustion reaction one side, the using plasma technology has covered one deck combustion catalyst layer on the top layer of metal foam, catalytic reforming reaction one side then the using plasma technology adhere to one deck reforming catalyst at the corresponding metal foam surface.Like this, can make catalyst in the environment of high-temperature, still have high viscosity and high mechanical properties, thereby make it durable in use.
The metal of plasma technique spraying can adopt metallic aluminium, titanium, or zirconia etc.Metal that these using plasma technology spray out or metal oxide can be so that the metallic support bottom avoid being subjected to the erosion of other media, meanwhile, can improve metallic support bottom service life at high temperature.
In addition, plasma technique can also use synthetic metal material as spray.
In plasma spraying technology of the present invention, the loose structure of plasma spray coating depends on outlet flow pattern (laminar flow, transition flow or turbulent flow), chemical composition, flow velocity, spray distance and spray power etc.
What need further specify is, the present invention does not limit to the form of above given embodiment, can also be transformed into other version.As change the quantity of interior pipe or the shape of change outer tube, the fluid that passes through in interior pipe and the sleeve pipe or fluid mixture following current or adverse current, but so long as the sleeve structure that has adopted the present invention to define all will fall into protection scope of the present invention.
