Definitions
- This invention relates generally to the production of hydrogen, and more specifically to the use of a membrane reactor for hydrogen production by the direct cracking of a hydrocarbon.
- Inorganic membranes such as palladium (Pd), palladium-silver (Pd-Ag) and several other alloys have been utilized in the past to separate hydrogen from other reactants and products in various reactions including hydrogenations, and dehydrogenations. Due to the high cost of these membranes, a great effort has been also devoted over the last several years to the development of composite and alloy membranes. Membranes of this type consist of a thin palladium film (providing permselectivity) coated on a porous or non-porous support that provides the required mechanical strength. A special type of membrane has been developed by Buxbaum and co-workers (J. Membr. Sci., 85, 29 (1993). and U.S. Patent Nos.
- This membrane takes advantage of the fact that several refractory metals such as niobium (Nb), tantalum (Ta), zirconium (Zr) and Vanadium (V) are one order of magnitude more permeable to hydrogen than palladium and have acceptable mechanical strength.
- An electroless plating technique was used to deposit a thin palladium film (1-2 ⁇ m thickness) on the surface of the refractory metals.
- Membranes prepared in this manner, and particularly Pd-Nb and Pd-Ta ensure high purity of the extracted hydrogen and are capable of permeating higher amounts of hydrogen than pure palladium membranes. In addition, they are stronger and more durable and can be used at higher temperatures.
- the present invention overcomes the problems described above and demonstrates the feasibility of producing substantially pure hydrogen by the direct cracking of hydrocarbons by the use of a membrane reactor.
- a membrane reactor can remove hydrogen from the reaction zone, and therefore, eliminate its negative effects on both reaction equilibrium and the reaction rate.
- the utilization of a membrane reactor can increase significantly the efficiency of the hydrogen production process.
- the membrane may be of any type of material that is selectively permeable only to hydrogen, and can thus effectively separate hydrogen from carbon monoxide and other components of the reacting mixture (e.g., unreacted hydrocarbons, carbon dioxide, water vapor, etc.).
- the invention has been ' * demonstrated with a Pd-Nb-type of membrane which is believed to have certain advantages as discussed in the background section of this application.
- the membrane preferably comprises Pd-Nb.
- the invention may be applicable to cracking any suitable hydrocarbon such as methane, natural gas, ethane, ethylene, propane, propylene, butane, pentane, hexane or mixtures thereof, and hydrocarbons with molecular weights in the gasoline and diesel range.
- the membrane reactor utilizes a catalyst bed which preferably comprises a nickel containing catalyst supported on a silica support.
- the hydrogen produced in the reactor zone selectively permeates through the membrane wall and is carried away by a sweeping gas.
- the reactor typically operates at a temperature in the range of about 400 to 900 °C.
- FIG. 1 is an enlarged side sectional view of the catalyst reaction zone of double tubular catalytic membrane reactor.
- FIG. 2 represents a plot of a comparison of methane conversion over 0.2 g of a 16 wt% Ni/Si0 2 catalyst at 550°C in a conventional fixed bed reactor and the reactor of Fig. 1.
- FIG. 3 represents a plot of the comparison of methane conversion over 0.2 g of a 16 wt% Ni/SiO 2 catalyst at 7600 h" 1 in a conventional fixed bed reactor and the reactor of Fig. 1.
- FIG. 4 is an enlarged side sectional view of the catalyst reaction zone of an alternative design of a fixed bed catalytic reactor having a membrane separator.
- the invention was demonstrated with the double tubular catalytic membrane reactor (10) depicted in Figure 1.
- the Pd-Nb membrane tube utilized has an outer diameter of 9.525 mm (3/8 in.) and a wall thickness of 0.25 mm; and was prepared according to the procedures described in the corresponding patents (U.S. 5,149,420 and 5,215, 729) covering its manufacture and use, which are incorporated herein by reference.
- the reactor consists of an inner membrane tube (12) and an outer stainless steel or quartz tube (14) which define a flow passageway (16).
- a catalyst bed (18) is located within the inner tube (12).
- Electrical heater (20) controls the reaction temperature.
- the hydrogen produced in the reactor zone selectively permeates through the membrane wall and is carried away by a sweeping gas indicated by the dotted arrows.
- the outer tube (SS, 1 in. OD, 0.028 in. thickness) is directly connected to a sweeping gas supply (not shown).
- the membrane occupied the central section of the inner tube and was connected to the reactor inlet and outlet with appropriate unions.
- the catalyst (16 wt% Ni/SiO 2 ) was packed within the membrane tube and the produced hydrogen was purged with an inert sweeping gas such as argon in the shell side. Additional hydrogen is also exiting the reactor at the bottom of the catalyst bed, as indicated by the solid arrows.
- Fig. 1 Another example of a membrane reactor configuration suitable for use in the present invention is shown in Fig. 4 wherein a fixed bed catalytic reactor or fuel processor is equipped with a membrane separator.
- the fuel processor which employs direct cracking, converts the hydrocarbon feed to hydrogen and carbon products and with the membrane separator, selectively extracts hydrogen to produce an essentially pure hydrogen product.
- the hydrocarbon gas is fed through an inlet port 42 and is cracked in internal chamber 44.
- the hydrogen formed from the cracking permeates the selectively porous membrane tubes 32 and travels to exit port 48 (see small arrows), while carbon monoxide, other reaction products, and unreacted hydrocarbons exit through port 46.
- the hydrocarbon gas feed enters one end of the reactor, passes through the catalyst bed, and the reaction products and unreacted hydrocarbons exit at the other end.
- the membrane separator the flow of the hydrogen goes from the outside to the inside of the membrane tubes.
- the flow of essentially pure hydrogen from all the membrane tubes are combined into a common header 50 and collected at exit port 48.
- Other alternate reactor configurations for this type of reactor in commercial operations may include fluidized bed or moving bed reactors.
- the catalyst used in the present invention will eventually deactivate as a result of carbon deposition.
- the carbon deposited on the catalyst may be recovered and used in electrochemical applications (superconductors, electrodes and fuel cells) or fuel storage applications.
- the deactivated catalyst can be fully regenerated by oxidization in air or steam gasification of the deposited carbon.
- Figure 2 compares the methane conversions obtained from a conventional fixed bed reactor and the reactor of Fig. 1 at 550°C at different space veloe ties.
- the CH 4 conversion in the conventional fixed bed reactor ranged from 31.7% at a space velocity of 60000 h "1 to 42.2% at 7500 h "1 .
