“…This paper aims to explore an effective approach to rapidly produce hydrogen from the steam reforming of methane by means of process intensification. The technology of catalytic partial oxidation also offers a promising reaction pathway for the rapid production of hydrogen from methane [9,10]. In contrast, the rate of methane steam reforming reaction is usually considered to be slow [5,6].…”

This paper addresses the issues related to the rapid production of hydrogen from methane steam reforming by means of process intensification. Methane steam reforming coupled with catalytic combustion in thermally integrated microchannel reactors for the production of hydrogen was investigated numerically. The effect of the catalyst, flow arrangement, and reactor dimension was assessed to optimize the design of the system. The thermal interaction between reforming and combustion was investigated for the purpose of the rapid production of hydrogen. The importance of thermal management was discussed in detail, and a theoretical analysis was made on the transport phenomena during each of the reforming and combustion processes. The results indicated that the design of a thermally integrated system operated at millisecond contact times is feasible. The design benefits from the miniaturization of the reactors, but the improvement in catalyst performance is also required to ensure the rapid production of hydrogen, especially for the reforming process. The efficiency of heat exchange can be greatly improved by decreasing the gap distance. The flow rates should be well designed on both sides of the reactor to meet the requirements of both materials and combustion stability. The flow arrangement plays a vital role in the operation of the thermally integrated reactor, and the design in a parallel-flow heat exchanger is preferred to optimize the distribution of energy in the system. The catalyst loading is an important design parameter to optimize reactor performance and must be carefully designed. Finally, engineering maps were constructed to design thermally integrated devices with desired power, and operating windows were also determined.

“…A common feature is related to the catalyst deactivation by coke deposition and/or by thermal sintering [3][4][5][6][7][8]9]. Thus far, SRM and POM are already deployed at the industrial scale for syngas production from natural gas [10][11][12], while DRM is still at a research and development stage. However, SRM is an energy-intensive process because of its high temperatures (ca.…”

“…Being cheaper than noble metals, transition-metal-based catalysts are suitable for partial oxidation reactions because of their ability to change oxidation states and adsorb reactants and intermediates onto their surface. 38 Overall, the partial oxidation reaction could be described as follows:…”

“…The product distribution of partial oxidation reactions depends upon the C/O ratio and is constrained by high reaction temperatures (>1000 °C); thus, partial oxidation reactions are usually carried out using heterogeneous catalysts at lower temperatures. Being cheaper than noble metals, transition-metal-based catalysts are suitable for partial oxidation reactions because of their ability to change oxidation states and adsorb reactants and intermediates onto their surface . Overall, the partial oxidation reaction could be described as follows: Thermodynamically, in this process, H 2 and CO are the most abundant products above 550 °C, with CO being a coke precursor, which can be removed by its oxidation toward CO 2 or by the water–gas shift reaction increasing the H 2 production.…”

Hydrogen Production Technologies: From Fossil Fuels toward Renewable Sources. A Mini Review

The global economic growth, the increase in the population, and advances in technology lead to an increment in the global primary energy demand. Considering that most of this energy is currently supplied by fossil fuels, a considerable amount of greenhouse gases are emitted, contributing to climate change, which is the reason why the next European Union binding agreement is focused on reducing carbon emissions using hydrogen. This study reviews different technologies for hydrogen production using renewable and non-renewable resources. Furthermore, a comparative analysis is performed on renewablebased technologies to evaluate which technologies are economically and energetically more promising. The results show how biomass-based technologies allow for a similar hydrogen yield compared to those obtained with water-based technologies but with higher energy efficiencies and lower operational costs. More specifically, biomass gasification and steam reforming obtained a proper balance between the studied parameters, with gasification being the technique that allows for higher hydrogen yields, while steam reforming is more energy-efficient. Nevertheless, the application of hydrogen as the energy vector of the future requires both the use of renewable feedstocks with a sustainable energy source. This combination would potentially produce green hydrogen while reducing carbon dioxide emissions, limiting global climate change, and, thus, achieving the so-called hydrogen economy.
