“…2M + 2H 2 O → 2MOH + H 2 (8) Many thermochemical cycles with metal oxide redox couple have been proposed [82], including Fe 3 O 4 /FeO [83][84][85][86], TiO 2 /TiO x [87], Mn 3 O 4 /MnO [88], Co 3 O 4 /CoO [89,90], ZnO/Zn [86,91,92], SnO 2 /SnO [93][94][95], CeO 2 /Ce 2 O 3 [96,97], CdO/Cd [98,99] and W/WO 3 [100]. The most investigated materials are zinc, iron and ceria metal oxides.…”

Green Synthetic Fuels: Renewable Routes for the Conversion of Non-Fossil Feedstocks into Gaseous Fuels and Their End Uses

Innovative renewable routes are potentially able to sustain the transition to a decarbonized energy economy. Green synthetic fuels, including hydrogen and natural gas, are considered viable alternatives to fossil fuels. Indeed, they play a fundamental role in those sectors that are difficult to electrify (e.g., road mobility or high-heat industrial processes), are capable of mitigating problems related to flexibility and instantaneous balance of the electric grid, are suitable for large-size and long-term storage and can be transported through the gas network. This article is an overview of the overall supply chain, including production, transport, storage and end uses. Available fuel conversion technologies use renewable energy for the catalytic conversion of non-fossil feedstocks into hydrogen and syngas. We will show how relevant technologies involve thermochemical, electrochemical and photochemical processes. The syngas quality can be improved by catalytic CO and CO2 methanation reactions for the generation of synthetic natural gas. Finally, the produced gaseous fuels could follow several pathways for transport and lead to different final uses. Therefore, storage alternatives and gas interchangeability requirements for the safe injection of green fuels in the natural gas network and fuel cells are outlined. Nevertheless, the effects of gas quality on combustion emissions and safety are considered.

“…These high thermal efficiencies from flowsheet evaluation show that cadmium based solar thermochemical hydrogen generating cycles have the potential to supply low cost hydrogen if the process are demonstrated to be practical and feasible. In addition to these cycles, Whaley et al had studied the hybrid cadmium cycle utilizing electrolysis to carry out the hydrolysis step (Whaley 1983). That approach was not considered in the present studies as the project aimed to study the feasibility of a pure thermochemical cadmium hydrogen cycle.…”

“…To circumvent the problems of recombination and materials selection, some lower‐temperature oxide cycles have been proposed. Some of these are based on oxides with lower reduction temperatures than ZnO (e.g., CdO and Mn 2 O 3 ) 26, 27. These oxides, when reduced, will not directly split water, so the process must be achieved through more than one additional step, as shown in Table 1.…”

Free-radical copolymerization of 4-nitrophenyl acrylate (NPA) with n-butyl methacrylate (BMA) was carried out using benzoyl peroxide as an initiator. Seven different mole ratios of NPA and BMA were chosen for this study. The copolymers were characterized by IR, 1 H-NMR, and 13 C-NMR spectral studies. The molecular weights of the copolymers were determined by gel permeation chromatography and the weight-average (M w ) and the numberaverage (M n ) molecular weights of these systems lie in the range of 4.3-5.3 ϫ 10 4 and 2.6 -3.0 ϫ 10 4 , respectively. The reactivity ratios of the monomers in the copolymer were evaluated by Fineman-Ross, Kelen-Tudos, and extended Kelen-Tudos methods. The product of r 1 , r 2 lies in the range of 0.734 -0.800, which suggests a random arrangement of monomers in the copolymer chain. Thermal decomposition of the polymers occurred in two stages in the temperature range of 165-505°C and the glass transition temperature (T g ) of one of the systems was 97.2°C.
