Description
METHODS FOR HYDROGEN PRODUCTION BACKGROUND OF THE INVENTION
[0001] The present invention provides for methods for producing biohydrogen.
[0002] There have been a number of efforts to produce renewable hydrogen that is cost competitive with conventional means of hydrogen production such as steam methane reforming. Often the process used for producing the hydrogen result in more expensive hydrogen due to the high cost of feedstock materials compared to natural gas and/or the high cost of processing the feedstock. Hydrogen produced from biomass feedstock is considered renewable but conventional methods are generally expensive.
One such conversion process is biomass gasification.
[0003] Biomass gasification to produce synthesis gas comprising mostly hydrogen, carbon monoxide and carbon dioxide is generically well known in the art. To keep the costs low, gasification is typically carried out by reacting biomass with air at elevated temperature from 500° to 1200°C and atmospheric pressure. The resulting gas therefore contains a large amount of nitrogen from air, resulting in dilution of the desired hydrogen and carbon monoxide components.
[0004] Furthermore, when hydrogen is the desired end product, separation of hydrogen by conventional means such as pressure swing adsorption (PSA) or membranes requires the raw gas to be first compressed to high pressures greater than about 7 bar. This is exacerbated also when hydrogen concentration in the feed gas is low, then hydrogen recovery is adversely affected.
[0005] One option is to use oxygen instead of air. However, oxygen, especially in small quantities, can be expensive. Further, the use of oxygen requires more expensive materials of construction for the reactor.
[0006]
Consequently, there are a number of factors that contribute to a high cost of hydrogen production.
[0007] The present invention uses a series of steps culminating in using an electrochemical separation device and multi-stage hydrogen compression system to produce hydrogen from the biomass. This process will reduce the use of syngas compression, lessens the need for high cost construction materials and produces high pressure hydrogen with the appropriate high purity in a single unit.
SUMMARY OF THE INVENTION
[0008] In a first embodiment of the invention, there is disclosed a method for producing hydrogen from biomass comprising the steps of: a) Feeding the biomass to a gasifier; b) Feeding the gasification products to a water gas shift reactor; c) Feeding the water gas shift reaction products to an electrochemical separation and compression device; and d) Recovering hydrogen.
[0009] The biomass is typically dried before being fed to the gasifier. This drying can be provided by heat taken from the electrochemical separation and compression device.
[0010] The gasifier will produce as gasification products hydrocarbons, hydrogen, carbon monoxide and carbon dioxide. These gasification products can be cooled by conventional cooling means before being fed to the water gas shift reactor.
[0011] The gasifier can be an atmospheric pressure gasifier which typically operates at atmospheric pressures and temperatures up to 600°C.
[0012] The water gas shift reactor will typically contain a catalyst. The water gas shift reactor will produce hydrogen and carbon monoxide (collectively synthesis gas) and carbon dioxide nitrogen and water vapor.
[0013] These water gas shift reaction products can be cooled by conventional cooling means after leaving the water gas shift reactor and before entering the electrochemical separation and compression device.
[0014] The electrochemical separation and compression device can operate on as little as 10 kwh/kg of current to separate hydrogen from the water gas shift reaction products. Typically this is occurring at pressures of around 7 to 14 bar. The multistage compressor portion of this device will compress the hydrogen in stages with cooling in between stages to arrive at a hydrogen product having pressures in the range of 150 to 350 bar.
[0015] In another embodiment of the invention there is disclose an apparatus for producing hydrogen from biomass comprising a gasifier in fluid communication with a water gas shift reactor in fluid communication with an electrochemical separation and compression device.
[0016] In the apparatus, the gasifier is an atmospheric pressure gasifier.
[0017] The water gas shift reactor contains a catalyst.
[0018] The apparatus further comprises a cooler in fluid communication with the gasifier and the water gas shift reactor.
[0019] The apparatus further comprises a cooler in fluid communication with the water gas shift reactor and the electrochemical separation and compression device.
BRIEF DESCRIPTION OF THE DRAWINGS
[0020] The figure is a schematic of a hydrogen production process according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
[0021] The figure is a schematic of hydrogen production according to the invention. Biomass and air are fed through line 1 into an atmospheric pressure gasifier A. Biomass is biological material derived from living or recently living organisms. Biomass typically includes virgin wood, energy crops, agricultural residues, food waste and industrial waste and co-products. The biomass will typically need to be dried before being fed to the atmospheric pressure gasifier A. This drying can be assisted through the use of low grade heat which can be retrieved from the electrochemical hydrogen separation and compression device. The atmospheric pressure gasifier A will operate at atmospheric pressures and temperatures up to 600°C to gasify the biomass to produce hydrocarbons, hydrogen, carbon monoxide, carbon dioxide, tars and water vapor. Ash and char will also be produced and these are discarded from the atmospheric pressure gasifier A. These reaction products will be fed through line 2 to a cooler B where the overall temperature of the reaction products is reduced. The cooled reaction products are fed to unit operation C. The resulting reaction products are fed through line 3 to a water gas shift reactor D.
[0022] In the water gas shift reactor D, carbon monoxide and water vapor will react to form carbon dioxide and hydrogen. Typically this operation is carried out in the presence of a catalyst and can operate at low (up to 250°C) or higher temperatures. The resulting reaction products of hydrogen and carbon dioxide will contain less than 1% carbon monoxide, as well nitrogen and water vapor and are fed through line 4 to a cooler E where they will be reduced in temperature. The cooled reaction products will be fed through line 5 to an electrochemical hydrogen separation and compression device F.
[0023] The electrochemical hydrogen separation and compression device F will operate to separate the hydrogen from the gas mixture fed to it and simultaneously compress the hydrogen to a desired pressure in the range of 7 to 14 bar and more preferably in the range of 5 to 10 bar. Higher pressures may also be produced should this be desired. The separation of the hydrogen from the other components fed from the water gas shift reaction process is fairly selective and is performed by applying a small amount of current across the electrodes designated “+” and above the electrochemical hydrogen separation and compression device F. This small amount of current is typically less than 10 kwh/kg of hydrogen and preferably is less than 5 kwh/kg of hydrogen.
[0024] This results in the production of hydrogen at the 7 to 14 bar pressure range of 99.997% purity which can then be fed through the multistage hydrogen compression portion of the electrochemical hydrogen separation and compression device F. The multi-stage hydrogen compression will produce hydrogen at 150 to 350 bar and this is recovered through line 6. The remainder of the gases separated from the hydrogen can be discharged through line 7 as a waste gas stream for treatment prior to discharge to the atmosphere.
[0025] The hydrogen produced by such method can be used in a fuel cell device for power production. There will of course be variations in the values expressed above due to the type, size and quality of feedstock and the conversion process selected. For example, a portion of the clean syngas produced from the water gas shift reaction can be fed to an engine to generate power while the remainder of the syngas can be used for hydrogen production.
[0026] While this invention has been described with respect to particular embodiments thereof, it is apparent that numerous other forms and modifications of the invention will be obvious to those skilled in the art. The appended claims in this invention generally should be construed to cover all such obvious forms and modifications which are within the true spirit and scope of the invention.
