Definitions
- the field of technology relates to the field of membrane technology and relates to the separation of gases on membranes, in particular, selective gas-tight membranes, in particular, when separating oxygen-containing gases for oxygen evolution and the use of oxygen in oxidative conversion reactions of hydrocarbon gas, in particular, to produce synthesis gas from methane.
- the prior art relates to the field of membrane technology and relates to the separation of gases on membranes, in particular, selective gas-tight membranes, in particular, when separating oxygen-containing gases for oxygen evolution and the use of oxygen in oxidative conversion reactions of hydrocarbon gas, in particular, to produce synthesis gas from methane.
- Oxidative conversion of hydrocarbon gas using oxygen-conducting membranes is a promising direction in the development of gas processing.
- the most common hydrocarbon gas conversion method at present is its steam conversion at elevated pressures (15–40 bar) and temperatures (800–850 ° C) [Nitrogen Handbook, 2nd ed., Revised. M: Chemistry, 1986, 512 s].
- the disadvantages of this method are the high energy consumption for heating the reactor and for producing high pressure water vapor.
- the oxygen-conducting membrane used in the process of membrane conversion is a ceramic plate or tube or a design of another convenient form for use.
- the membrane has sufficient oxygen conductivity at high temperatures, typical of the process of partial oxidation of hydrocarbon gas.
- the membrane is gas tight, that is, it is made of non-porous material.
- the membranes used for air separation have ionic or mixed electron-ionic conductivity. In both cases, driven by a partial pressure gradient, oxygen ions pass through a dense non-porous membrane with high speed and absolute selectivity.
- the process of membrane conversion of hydrocarbon gases, in particular methane is as follows: an oxygen-containing gas (e.g. air) is supplied from one side of the membrane (e.g., outside the tubular membrane), hydrocarbon gas (e.g. methane) from the other side (respectively, inside the pipe membranes).
- an oxygen-containing gas e.g. air
- hydrocarbon gas e.g. methane
- gas-tight oxygen-conducting membranes in the process of oxidative conversion of methane to synthesis gas is a radical improvement of existing technologies for the conversion of hydrocarbons, leading to increased efficiency and simplification of the process.
- a key component of this technology is a ceramic membrane, which provides oxygen transfer to the reaction zone. It is known that the most promising materials in the manufacture of gas-tight membranes for the evolution of oxygen from mixtures containing, in particular, oxygen-containing gas, are complex oxide compounds with ionic and / or electronic conductivity and with perovskite structure. For industrial applications, sufficient rates of diffusion of oxygen from air or other similar oxygen-containing gas through such membranes are speeds of 1.5-2.5 nm 3 / m 2 s.
- the thickness of the perovskite membrane should not exceed 15-30 microns, which makes it mechanically unstable in practical use.
- said membrane is protected on one or two sides by means of a mechanically strong gas-permeable layer chemically or adhesively bonded to it.
- a mechanically strong gas-permeable layer chemically or adhesively bonded to it.
- porous ceramics or metal alloys of various compositions and various shapes are usually used. Complex structures created in this way are called composite membranes.
- US Pat. No. 5,599,383 describes composite membranes comprising a thin layer of dense oxygen and electron-conducting ceramics with a perovskite structure from 0.01 to 500 ⁇ m thick, a layer of porous ceramic carrier made of a material selected from the group consisting of metal oxides such as aluminum, cerium, silicon, magnesium, titanium, a high-temperature oxygen-containing alloy stabilized with zirconium, and mixtures thereof.
- metal oxides such as aluminum, cerium, silicon, magnesium, titanium
- a high-temperature oxygen-containing alloy stabilized with zirconium and mixtures thereof.
- a disadvantage of the known membranes is insufficient strength due to differences in the coefficients of thermal expansion of the gas-tight membrane and the protective gas-permeable layer (s).
- a composite membrane known from US Pat. No. 5,935,533, which includes a continuous layer of gas-tight oxide ceramics with ionic and / or electronic conductivity, for example, with a perovskite structure, a porous support layer of high temperature steel containing nickel and chrome, placed on one or both sides of the ceramic, and between the indicated layers of ceramic and the carrier interfacial zone of the gradient composition (buffer layer).
- the disadvantage of this technical solution is the lack of strength of the membrane, due to the difference in the coefficients of thermal expansion of metal and ceramics.
- Another disadvantage of the known solution is the uncertainty of the properties of the composite membrane, which is associated with the presence in it of an intermediate buffer layer with a thickness of at least 5 ⁇ m, having an indefinite, time-varying composition, since the buffer layer is formed as a result of diffusion into the ceramic, at least one element of an alloy containing nickel and chromium.
- the main task to which the proposed invention is directed is to create a composite oxygen-conducting membrane with high mechanical strength and having optimal characteristics of gas density and oxygen permeability.
- the main task has been solved by the fact that in a composite oxygen-conducting membrane containing a continuous ceramic layer with ionic and / or electronic conductivity and at least one layer of a gas-permeable structure made of an alloy containing elements of groups VIII and VI of table D. AND. Mendeleev, an alloy is used for the gas-permeable layer, which additionally contains aluminum.
- an alloy is used for the gas-permeable layer, which additionally contains aluminum.
- the additional inclusion of aluminum in the composition of the alloy used for the gas-permeable layer makes it possible to reduce the difference in the linear expansion coefficients of the protective layer and the ceramic layer, as well as to prevent the diffusion of the used alloy into the ceramic layer, which leads to an increase in strength and gas-tightness of the composite oxygen-conducting membrane.
- the composite oxygen-conducting membrane contains two layers: the first layer is continuous and made of ceramic having ionic or mixed electron-ion conductivity, the second layer is gas-permeable and made of a metal alloy containing iron and chromium as elements VIII and VI groups of the periodic table D.I. Mendeleev.
- the use of iron and chromium allows to achieve the best alignment of the coefficients of thermal expansion.
- the gas permeable layer is made in the form of a layer with holes, which allows to obtain the best gas permeability of this layer.
- the holes in the layer of the gas-permeable structure are made in the form of pores. This improves the uniformity of the deposition of a continuous ceramic layer, which leads to an improvement in the oxygen permeability of the composite membrane.
- the layer of gas-permeable structure with holes is made in the form of a grid. This embodiment provides an increase in manufacturability.
- the composite oxygen-conducting membrane consists of three layers, namely, two layers of a gas-permeable structure made of an alloy containing elements of groups VIII and VI of the periodic table DI Mendeleev, and a continuous layer of ceramic located between them, having ionic or mixed electron-ionic conductivity.
- FIG. 1 shows a tubular composite membrane.
- FIG. 2 shows a flat (planar) composite membrane.
- FIG. 3 is a diagram of an apparatus for measuring the oxygen permeability of gas-tight membranes.
- a composite oxygen-conducting membrane according to this invention is made by applying a first continuous ceramic layer to a second gas-permeable layer made of an alloy containing elements of groups VIII and VI of the periodic table DI Mendeleev, which additionally contains aluminum.
- Methods for applying a gas-tight perovskite layer to a gas-permeable layer (or substrate) are selected based on the geometry of the composite membrane being manufactured and the conditions for its use.
- known methods for applying perovskite known methods are used such as pressing, sol-gel deposition from solutions, chemical vapor deposition, laser or plasma spraying, centrifugal coating, etc.
- the geometry of the membrane is determined by the method of its use, while the membrane can be, respectively, flat, tubular, corrugated, etc.
- a composite oxygen conducting membrane is made in the form of tubes, as, for example, shown in FIG. 1, or in the form of plates, as shown in FIG. 2.
- the chemical composition of the protective metallic porous layer (s), as well as the shape, size and location of the pores, are selected in such a way as to avoid damage to the integrity of the gas-tight membrane due to differences in the thermal expansion coefficients of the gas-tight membrane and the protective gas-permeable layer (s). In the present invention, this is achieved through the use of an alloy containing elements of groups VIII and VI of the periodic table D.I. Mendeleev and aluminum.
- the tubular composite membrane has an outer layer (1), which is a dense oxygen- and electron-conducting ceramic membrane, and an inner layer (2), which is a gas-permeable metal protective layer in which holes (3) are made.
- a flat (or planar) composite membrane is presented, consisting of two interrogated protective metal layers (2) having pores (3), and a gas-tight oxygen and electron-conducting ceramic membrane (1) located between them.
- the composite membrane of the invention can be used to separate gases, in particular oxygen-containing gases, to isolate oxygen and use it in oxidative conversion reactions of hydrocarbon gas, for example, in the production of synthesis gas from methane.
- the composite membrane is fixed in the conversion reactor so that the cavity of the reactor is divided into two parts by means of this membrane.
- Oxygen-containing gas is supplied to one part, methane is supplied to the other, which reacts with oxygen released from the gas mixture after passing through the membrane to form synthesis gas.
- the installation for measuring the oxygen permeability of gas-tight membranes includes a line for supplying an oxygen-containing gas, in particular air, a line for supplying helium, additionally free of traces of oxygen, a measuring cell (2) with two chambers (G) separated by a membrane (2a) and (26), in the first of which air is supplied, and in the second - purified helium, a tone valve adjustment (5) and a system for analyzing helium passing through the measuring cell (2) for the oxygen and nitrogen content in the gas mixture passing through the composite membrane.
- the composite membrane (1) is placed in the cell (2), which is a hollow metal vessel in which the membrane (1) is fixed.
- This fastening is carried out in such a way that the membrane divides the cell (2) into two chambers: a chamber (2a) for a helium flow, previously purified in an absorber with metal copper heated to a temperature of 200 ° C, and a chamber (26) for air flow.
- a fine adjustment valve (5) the pressure is equalized on both sides of the membrane (1) in the cell (2).
- the gas leaving the chamber (2a) of the cell (2) is sent to the analysis system to determine the content of nitrogen and oxygen in it.
- the specified analysis is carried out by any known method, for example, by chromatography or mass spectrometry.
- Example 1 An alloy containing iron, chromium and aluminum was used to solve the problems of the present invention.
- the composite membrane thus obtained is placed in a cell for checking gas tightness.
- the operation is repeated three times, changing the heating and cooling rates, as well as the time exposure at elevated temperatures.
- the nitrogen concentration in the helium leaving the cell did not exceed 10 "5 mole fractions, which indicates the gas density of the composite membrane.
- the oxygen concentration in the flow varied depending on temperature from 10 ⁇ 5 to 10 " mole fractions , which confirms the oxygen permeability of the composite membrane.
- Example 2 comparative
- Example 3-7 A composite membrane is made by the method described in Example 1, varying the form of execution of a mechanically strong protective layer, i.e. instead of metal foil with round holes, various types of protective layer (metal substrate) are used.
- the results of the gas permeability study of a mechanically strong protective layer containing holes of various shapes and sizes, in particular, made in the form of a porous foil or mesh, are shown in the Table.
- the invention is intended for gas separation, in particular for the separation of oxygen-containing gases for oxygen evolution and its use in oxidative conversion reactions of hydrocarbon gas, in particular for the production of synthesis gas from methane.
