Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. The procedure of alkylation has an advantage over other practices in this respect because it does not produce any aromatic compounds which is why it is favored in use over other reforming types. Menu Close The CEA (2021) estimates its price at 1.5/kg of H2. O S O Zero carbon 'green' hydrogen is produced by thermochemical water splitting, using solar thermal, low- or zero-carbon electricity or waste heat,[2] or electrolysis, using low- or zero-carbon electricity. Due to the exothermic nature of some of the additional reactions occurring within ATR, the process can essentially be performed at a net enthalpy of zero (H = 0). 1 0 obj [18], In addition to reactions [1] [3], ATR introduces the following reaction:[19], [ [16][17], Autothermal reforming (ATR) uses oxygen and carbon dioxide or steam in a reaction with methane to form syngas. [3], Steam reforming of natural gas produces most of the world's hydrogen. AIChE Journal; New YorkVol. k The most suitable and probably most important type of fuel cell for numerous applications is the proton exchange membrane fuel cell. Steam reforming is currently probably the most common large-scale industrial process for the production of hydrogen from carbonaceous resources such as natural gas and biomass. The process of steam reforming to hydrogen usually uses natural gas or residues from the petroleum industry, which are enriched with steam. C The steam and hydrocarbon are then brought together in a pre-reforming unit, where all high-grade hydrocarbons are converted directly to C1 [=1-carbon?] The key difference between steam reforming and autothermal reforming is that steam reforming uses the reaction of hydrocarbons with water, whereas autothermal reforming uses oxygen and carbon dioxide or steam in reaction with methane to form syngas. However, you may visit "Cookie Settings" to provide a controlled consent. The advantage of ATR is that the H2:CO ratio can be varied, which can be useful for producing specialty products. 3 There are several challenges associated with this technology: Challenges with reformers supplying fuel cells, Chemical looping reforming and gasification, "A review and comparative evaluation of thermochemical water splitting cycles for hydrogen production", "Mathematical modelling and simulation of the thermo-catalytic decomposition of methane for economically improved hydrogen production", "Methane steam reforming, methanation and water-gas shift: I.

International energy information, including overviews, rankings, data, and analyses. H l However, analyses have shown that even though it is more costly to construct, a well-designed SMR can produce hydrogen more cost-effectively than an ATR. However, comparing the use of biogas and biomass with that of natural gas, there are several disadvantages compared to the fossil fuel. [16], In an effort to decarbonise hydrogen production, carbon capture and storage (CCS) methods are being implemented within the industry, which have the potential to remove up to 90% of CO2 produced from the process. The cost of hydrogen production by reforming fossil fuels depends on the scale at which it is done, the capital cost of the reformer, and the efficiency of the unit, so that whilst it may cost only a few dollars per kilogram of hydrogen at an industrial scale, it could be more expensive at the smaller scale needed for fuel cells. Estimates are generally that, in total, producing 1kg of H2 by steam methane reforming releases 8-10kg of CO2. [29][self-published source?]. Flared gas and vented volatile organic compounds (VOCs) are known problems in the offshore industry and in the on-shore oil and gas industry, since both release greenhouse gases into the atmosphere.
