Summary: Electrified methane steam reforming (eMSR) is a promising concept for low-carbon hydrogen production. The innovative eMSR reactor uses SiSiC foams coated with Rh/Al2O3 catalyst as electrical resistances to generate reaction heat. The system achieves complete methane conversions even at a high space velocity of 200000 Nl/h/kgcat, with a specific energy demand as low as 1.24 kWh/Nm3H2 and an unprecedented energy efficiency of 81%.

Summary: We present a rapid pulse Joule heating (RPH) reactor with an in situ Raman spectrometer for highly endothermic, reversible reactions, showcasing its application in methane dry reforming over PtNi/SiO2 catalysts. The RPH reactor achieves a catalyst temperature ramp rate of approximately 14000 °C/s, thanks to the low thermal mass and resistivity of the heating element. The use of Joule heating elements allows for temperatures that were previously unachievable, leading to improved performance and energy efficiency.

Summary: In this paper, researchers prepared an electrically heated monolithic catalyst (EHMC) substrate by arranging multi-segment helical FeCrAl substrates in tube-shell form with insulation by honeycomb ceramics, followed by thermal treatment and catalyst deposition. The start-up and catalytic performance of the EHMC under different reaction conditions were experimentally studied. The results showed that the EHMC could reach the desired temperature of 275 degrees C in 29 s with a uniform temperature distribution by supplying a current of 2 A in air atmosphere. Compared to the commercial granular catalyst under external heating condition, the EHMC exhibited better catalytic activity with higher methanol conversion and similar CO concentration at low reaction temperature. Furthermore, when the methanol conversion was 90%, the GHSV of the EHMC was 5.54 times that of the commercial granular catalyst, indicating its enhanced mass and heat transfer ability.

Summary: Most industrial catalytic reactions waste a significant amount of energy due to the dissipation of heat into the bulk, rather than focusing it on the catalyst surface. In this study, a local Joule heating method was proposed, using an electric current passing through packed catalyst nanoparticles with a large contact resistance to generate heat specifically at the surface region. This method showed improved efficiency and reduced energy input compared to traditional external heating.

Summary: This study presents a detailed process modeling study on CO2 utilization via the rWGS reaction. The results show that greenhouse gas emissions are the lowest when wind-generated electricity is used. However, when considering electrification, the total design perspective needs to be carefully considered to avoid producing more greenhouse gases than conventional non-electrified scenarios.
