“…The temperature increase was measured while applying the magnetic alternating field (heating curve), and the temperature decrease after turning off the field (cooling curve). We have computed the SAR at each temperature by subtracting the slope of the heating curve from the slope of the cooling curve at the same temperature, following Varsano et al11 The temperature dependence of C p values of Fe and Co have been obtained from Touloukian et al43 The C p values ofFe x Co 1-x -NP have been calculated by considering the atomic fraction weighted average of the C p of iron and the C p of Co. Catalytic tests Catalytic tests were performed in a quartz tube continuous-flow reactor of 1 cm diameter surrounded by an inductor delivering an AC magnetic field oscillating at a frequency of 300 kHz with a rms amplitude adjustable between 0 and 65 mT.…”

Magnetic heating by nanoparticles has recently been successfully employed in heterogeneous catalysis. In such processes, the maximum temperature that can be reached depends on the Curie temperature (T c) of the heating material. Here, in order to extend the range of accessible temperatures and consequently the range of possible reactions, to those requiring high temperatures, we developed and fully characterized a series of FeCo nanoparticles containing different concentrations of cobalt, in order to tune their magnetic properties and Tc. Their efficiency is compared to that of iron carbide nanoparticles, which display a lower Tc. Specific Absorption Rate (SAR) measurements as a function of temperature, performed using a homemade pyrometer-based setup, clearly show that, although the heating power of iron carbide nanoparticles is higher at room temperature, it decreases more rapidly with temperature than that of iron cobalt nanoparticles, in agreement with their lower Tc. In a showcase, Fe 0.5 Co 0.5 nanoparticles allow, in addition to CO 2 hydrogenation, dry reforming of propane and methane, and dehydrogenation of propane, these reactions requiring temperatures of 350°C, 600°C and 700°C respectively. Furthermore, the use of Fe 0.5 Co 0.5 nanoparticles is less energy demanding, as it allows carrying out CO 2 hydrogenation at lower magnetic fields and at frequencies as low as 100 kHz. Dry reforming of methane and propane were carried out in the presence of a Ni nanoparticle-based catalyst whereas dehydrogenation of propane required as a catalyst PtSn nanoparticles synthesized through an organometallic route. Fe 0.5 Co 0.5 nanoparticles can therefore be used as universal heating agents allowing performing reactions up to ca. 700°C upon association with the appropriate catalyst.

Induction heating of magnetic nanoparticles (NPs) is a method to activate heterogeneous catalytic reactions. It requires nano‐objects displaying high heating power and excellent catalytic activity. Here, using a surface engineering approach, bimetallic NPs are used for magnetically induced CO2 methanation, acting both as heating agent and catalyst. The organometallic synthesis of Fe30Ni70 NPs displaying high heating powers at low magnetic field amplitudes is described. The NPs are active but only slightly selective for CH4 after deposition on SiRAlOx owing to an iron‐rich shell (25 mL min−1, 25 mT, 300 kHz, conversion 71 %, methane selectivity 65 %). Proper surface engineering consisting of depositing a thin Ni layer leads to Fe30Ni70@Ni NPs displaying a very high activity for CO2 hydrogenation and a full selectivity. A quantitative yield in methane is obtained at low magnetic field and mild conditions (25 mL min−1, 19 mT, 300 kHz, conversion 100 %, methane selectivity 100 %).

“…The data used in the present study take the heat and electricity consumption for CO 2 separation and compression by amine scrubbing into consideration (Reiter and Lindorfer 2015). According to the American Physician Society, this technology is less energy-consuming than DAC (1.16 kWh/kgCO 2 ) due to a higher concentration of CO 2 in the industrial smokes (Socolow et al 2011). Moreover, it has been recently reported that the energy consumption of amine scrubbing based on the use of MEA for carbon capture is not expected to be significantly reduced (Bui et al 2018).…”

Purpose Technologies with low environmental impacts and promoting renewable energy sources are required to meet the energetic demand while facing the increase of gas emissions associated to the greenhouse effect and the depletion of fossil fuels. CO 2 methanation activated by magnetic heating has recently been reported as a highly efficient and innovative power-togas technology in a perspective of successful renewable energy storage and carbon dioxide valorisation. ln this work, the life cycle assessment (LCA) of this process is performed, in order to highlight the environmental potential of the technology, and its competitivity with in respect to conventional heating technologies. Methods The IMPACT 2002+ was used for this LCA. The process studied integrates methanation, water electrol ys is and CO 2 capture and separation. Thi s "cradle-to-gate" LCA study does not consider the use of methane, which is the reaction product. The functional unit used is the energy content of the produced CH.i. The LCA was carried out using the energy mix data for the years 2020 and 2050 as given by the French Agency for Environment and Energy management (AD EME). Consumption data were either collected from Iiterature or obtained from the LPCNO measurements as discussed by Marbaix (2019). The environmental impact of the CO 2 methanation activated by magnetic heating was compared with the environmental impact ofa power-togas plant using conventional heating (Helmeth) and considering the environmental impact of the natural gas extraction. Results lt is shown that the total flow rate of reactants, the source of CO 2 and the energy mix play a major role on the environmental impact of sustainable CH 4 production, whereas the lifetime of the considered catalyst has no significant influence. As a result ofthe possible improvements on the above-mentioned parameters, the whole process is expected to reduce by 75% in its environmental impact toward 2050. This illustra tes the high environmental potential of the methanation activated by magnetic heating when coupled with industrial exhausts and renewable electricity production. Conclusions The technology is expected to be environmentally competitive compared with existing sirnilar processes using external heating sources with the additional interest of being extremely dynamic in response, in Iine with the intermittency of renewable energy production.
