“…Another conversion approach that was reported in literature for dry reforming of methane was reported by Labrecque and Lavoie in 2011. In this work, the authors claimed that the utilization of an electrified fixed bed of steel wool allowed high conversions both of methane and of carbon dioxide [25]. This approach could possibly lead to new and disruptive innovations in the field since it used a catalyst that was not extensively reported in that field before and a reactive system that was overall complex although simpler and cheaper to scale than the plasma-based systems.…”

With the increasing world's energy demand along with the constantly expanding field of natural gas exploitation around the world, dry reforming of methane has gained increasing attention. Through this technology, natural gas can be converted into syngas, which is a well-known building block used for the production of alcohols and fuels. This technology has become an interesting approach for the valorization of a variety of CO 2 streams and for the reduction of the natural gas carbon footprint. In this work, attention will be given to the different reforming technologies used at industrial scale, followed by an investigation of the different approaches used for dry reforming of methane. Furthermore, focus will be given on how natural gas reforming could be used as a vehicle to store renewable energy while trying as well to reduce the carbon footprint of this technology. The technology presented in this work was previously developed by Hydro Québec and uses a cheap and available catalyst in addition to electricity to convert methane and carbon dioxide into syngas. Reactants conversions were up to 99% and the syngas produced had a H 2 /CO ratio of 1 for over 200h.

Dry reforming of methane (DRM) has been investigated under an electronactivated catalytic bed in a thermo-electrical reactor. The main objective of this work was to investigate what the impact of the electrical current on the conversion of methane is. The combination of thermal and electrical energy allowed achieving higher conversions for both reactants at temperatures varying from 850-950°C. The electrical current at the different temperatures investigated during this work affected the conversion of methane and a threshold was pinpointed for different temperatures. At this point, the conversion of methane increased exponentially with the current provided to the catalyst. Furthermore, in order to confirm the catalytic potential of steel wool, different grades of stainless steel were tested for the DRM as well, showing lower conversion in all cases, in comparison to the carbon steel wool.

“…Of course, the energy balance is also a significant concern as well as the nature of the energy, which should ideally be produced with minimal amounts of emitted CO 2 . Recently, our team has reported on the dry reforming of methane and CO 2 in an electron-activated iron catalytic bed [7]. Using hydroelectricity, a green energy abundant in many regions of the world including in the province of Quebec (Canada), methane (that could come from biogas, flue gas, or even tail gas of second generation biofuel processes) was oxidized to syngas using carbon dioxide as oxidant as depicted by the reaction below:…”

Dry reforming is a process allowing simultaneous conversion of hydrocarbons (methane being the prototype molecule used for this study) to syngas using carbon dioxide as an oxidizing agent. Such strategy may eventually become an opportunity for the industrial sector to produce syngas whilst valorizing residual CO 2 . As reported previously, an iron-based catalyst, i.e. steel wool, activated by an electrical current showed potential for dry reforming. As a follow up to this preliminary work, this study mainly focuses on the characterization of the lowcost thin iron wires in order to determine the robustness and stability of the iron material over extended operation. Under CO 2 /CH 4 molar feed ratios ranging from 0.8 to 1.25, coking is inhibited by high surface temperature. After 25 hours of operation at a temperature higher than 900°C measured in the gas phase, XRD patterns show a preserved Fe structure along with FeO suggesting an eased redox cycle with CO 2 and CH 4 . It is also showing that a high CO 2 /CH 4 ratio favors higher oxidation states of the iron in the zone of the iron bed, which is first in contact with the gas input. Decreasing the temperature to 800°C favors oxidation by CO 2 over reduction by CH 4 leading to Fe 3 O 4 formation. This disturbs the Joule dissipation through the wire mesh catalyst bed. Although high molar ratios of CO 2 over CH 4 result in fast oxidation of the catalyst, reducing the ratio may lead to increasing the catalyst lifespan which, overall, is essential to scale this process to a commercial scale.
