“…Knowing these challenges to existing technology, it was realized that microstructured reactors could potentially lead to significant process intensification by clever heat transfer designs [10,52,53]. A good example is the calculations by Velocys and others on the potential for SMR intensification by efficient heat exchange by heating channels for catalytic combustion integrated between reaction channels and catalyst utilization.…”

“…e. Small scale production of hydrogen pursued as a possible enabler of a future fuel cell and hydrogen based society [8][9][10]. However, car manufacturers have mostly abandoned fossil-to-hydrogen routes that do not involve CO 2 capture and storage (CCS), in recognition of the need to abate climate change in future energy systems.…”

“…And since the scale-up to commercial production is intended to happen by parallelization, the properties are maintained or transferred to the larger scale, leading also to new challenges. Such reactor technology has been developed mainly over the recent 20 years, with a few research environments as pioneers; the German Forschungszentrum Karlsruhe (now Karlsruhe Institute of Technology) [16][17][18][19][20] and Institut für Mikrotechnik Mainz (now Fraunhofer ICT-IMM) [9,10,15,21], and the US Pacific Northwest National Laboratory (PNNL-Battelle) [22] among the most active. The microstructured reactors' properties and potential have also been extensively reviewed and analyzed [15,23,24].…”

Synthesis gas production and further conversion via the Fischer-Tropsch, methanol and dimethyl ether (DME) syntheses is currently economic only in the large scale. Compact, modular, and safe technology efficient in smaller scale would enable utilizing smaller natural gas fields, bio-syngas and even off-shore associated gas that otherwise would be flared or re-injected. So-called or microstructured reactors with superior heat and mass transfer properties and scalability by parallelization may offer opportunity for process intensification and different investment risk. Here, we summarize research into the performance of different combinations of catalyst properties and microchannel design.We find that intensified production of synthesis gas by steam reforming or catalytic partial oxidation remains associated with significant challenges to the reactor design, the catalysis and the materials. With respect to synthesis of methanol, DME or Fischer-Tropsch products, using a microchannel packed-bed with integrated heat exchange, the results are definitely more encouraging, enabling the use of highly active catalysts and severe process conditions without sacrificing on selectivity and stability.

“…LNCCe catalyst does not contain an oxygen ion conductor whereas YNCCe catalyst does not contain a selective cathode. Ni-Cu-CeO 2 catalyst was used as a reference because Ni, Cu, and CeO 2 were the main components of YLNCCe, the SSEP catalyst and because Ni-Cu-CeO 2 was a conventional catalyst system for hydrocarbon reforming (15)(16)(17). A Pt-CeO 2 catalyst form www.fuelcellmaterials.com was used for comparing the SSEP catalyst with a noble metal catalyst.…”

Development and Study of Self-Sustained Electrochemical Promotion Catalysts for Hydrocarbon Reforming

A series of study on self-sustained electrochemical promotion (SSEP) catalysts are summarized. The SSEP catalyst enables more than 90% conversion and 90% hydrogen sensitivity at temperatures of 450 -650 ºC for methane and n-pentadecane reforming. The conversion and sensitivity is up to two orders of magnitude greater than those over Ni based catalyst and a commercial Pt catalyst at 450-550°C. The kinetic models incorporating LangmuirHinshelwood model and SSEP effect successfully describe the major characteristics of hydrocarbons reforming over the SSEP catalyst. This concept of SSEP catalyst may provide a new route for developing high performance catalysts for hydrocarbons reforming.
