“…It is well known that the process can be performed in the kinetic regime by applying very thin sorbent layers onto structured supports [44]. Recently, the application of metal wires, gauzes and foams as support for reforming catalysts and sorbents is also considered [45]. The maximum temperature during the desorption step cannot be increased above 1173 K as this would substantially reduce the lifetime of CaO sorbent.…”

Several problems with stabilization of electricity grid system are related to the time lag between the electricity supply and demand of the end users. Many power plants run for a limited period of time to compensate for increased electricity demand during peak hours. The amount of CO2 generated by these power installations can be substantially reduced via the development of new demand side management strategies utilizing CO2 absorption units with a short start-up time.The sorbent can be discharged using radiofrequency (RF) heating to fill the night-time valley in electricity demand helping in the stabilization of electricity grid. Herein a concept of RF heated fixed bed reactor has been demonstrated to remove CO2 from a flue gas using a CaCO3 sorbent. A very stable and reproducible operation has been observed over twenty absorptiondesorption cycles. The application of RF heating significantly reduced the transition time required for temperature excursions between the absorption and desorption cycles. The effect of flow reversal during desorption on desorption time has been investigated. The desorption time was reduced by 1.5 times in the revered flow mode and the total duration of a single absorption-desorption cycle was reduced by 20%. A reactor model describing the reduced desorption time has been developed. 2 Highlights• An RF reactor system has been demonstrated for post-combustion carbon capture.• The transition time between the absorption and desorption cycles was reduced by 2 times as compared to conventional heating• The reverse CO2 desorption flow mode reduced the desorption time by 1.5 times.• The energy efficiency of RF heated and conventionally heated bench reactors was compared

“…Particularly, this new structure is opening an opportunity on the development of novel monolithic catalyst with significantly enhanced heat transfer that is desired for suppressing the catalytic bed 'hot-or cold-spots' formation in the strongly exo-or endo-thermic reaction processes. So far, some foam-structured catalysts using SiC foam [13], compressed Ni-Al foam [14] and stainless steel metal foam [15], have been reported for the methane reforming processes. Such catalysts obtained via traditional wash-coating, dipcoating or extrusion methods [16,17], however, suffer from the random distribution of active components, detachment of coatings, binder harmful contamination, and the blockage of channels [18].…”

“…The reactor was a double walled quartz reactor tube and the absorber/reformer was placed in the inner tube behind the quartz window ( Figure Figure 8 shows that the alumina supported catalyst is better in terms of sustaining activity throughout the entire test [49]. It also shows that Ru is best in terms of maintaining activity for extended periods of operation [49,51]. The alumina support was applied in two different ways and a comparison of the two methods is shown in Figure 9.…”

Because of the increasing demand for energy and the associated rise in greenhouse gas emissions, there is much interest in the use of renewable sources such as solar energy in electricity and fuels generation. One problem with solar energy, however, is that it is difficult to economically convert the radiation into usable energy at the desired locations and times, both daily and seasonally. One method to overcome this space-time intermittency is through the production of chemical fuels. In particular, solar reforming is a promising method for producing chemical fuels by reforming and/or water/carbon dioxide splitting. In this paper, a review of solar reforming systems is presented, as well as a comparison between these systems and a discussion on areas for potential innovation including chemical looping and membrane reactors. Moreover, a brief overview of catalysis in the context of reforming is presented.
