“…Catalyst synthesis via the sol-gel process is also commonly employed as it provides the means to control the surface and textural properties [47,62]. As the process is a wet chemical technique, it is also known as chemical solution deposition [61,139].…”

“…Liu et al [62] compared the activity of LaNiO 3 and LaNi 0.8 M 0.2 O 3 perovskites substituted in the B site with Fe, Co, Mn, and Cu on the SR of acetic acid and showed that activity followed the order: LaNi 0.8 Fe 0.2 O 3 > LaNi 0.8 Co 0.2 O 3 > LaNiO 3 > LaNi 0.8 Mn 0.2 O 3 > LaNi 0.8 Cu 0.2 O 3 . In another work [61] the same authors also studied a series of Fe-doped LaNiO 3 perovskites with different Ni/Fe ratios and concluded that despite LaNiO 3 showing higher activity for hydrogen production, the Ni-Fe bimetallic perovskites were more stable during the SR process. Among the partial substituted perovskites that have been examined, LaNi 0.8 Fe 0.2 O 3 demonstrated the best synergy between Ni and Fe.…”

“…The B site particularly, is a cation with a coordination number of six and it is the central site of structure [62]. Due to the great flexibility of the crystal lattice structure, partial substitution of cations in A and B position by other elements of a similar size can be achieved, resulting in significant changes to the catalyst's properties [61,71]. In addition, perovskites combine both high loadings of metals and high dispersion, preventing the agglomeration of metal ions incorporated in their lattice.…”

Recent Progress in the Steam Reforming of Bio-Oil for Hydrogen Production: A Review of Operating Parameters, Catalytic Systems and Technological Innovations

The present review focuses on the production of renewable hydrogen through the catalytic steam reforming of bio-oil, the liquid product of the fast pyrolysis of biomass. Although in theory the process is capable of producing high yields of hydrogen, in practice, certain technological issues require radical improvements before its commercialization. Herein, we illustrate the fundamental knowledge behind the technology of the steam reforming of bio-oil and critically discuss the major factors influencing the reforming process such as the feedstock composition, the reactor design, the reaction temperature and pressure, the steam to carbon ratio and the hour space velocity. We also emphasize the latest research for the best suited reforming catalysts among the specific groups of noble metal, transition metal, bimetallic and perovskite type catalysts. The effect of the catalyst preparation method and the technological obstacle of catalytic deactivation due to coke deposition, metal sintering, metal oxidation and sulfur poisoning are addressed. Finally, various novel modified steam reforming techniques which are under development are discussed, such as the in-line two-stage pyrolysis and steam reforming, the sorption enhanced steam reforming (SESR) and the chemical looping steam reforming (CLSR). Moreover, we argue that while the majority of research studies examine hydrogen generation using different model compounds, much work must be done to optimally treat the raw or aqueous bio-oil mixtures for efficient practical use. Moreover, further research is also required on the reaction mechanisms and kinetics of the process, as these have not yet been fully understood.

“…[172] For LaNi x Fe 1-x O 3 perovskite oxygen carriers, tuning the Fe to Ni could result in optimal CLBP performance over repeated redox cycles. [177,178] When using perovskite OCs, special attentions must be paid to the reversibility of phase changes over long-term redox cycling. For example, deep reduction of CaMnO 3 could result in the irreversible accumulation of CaMn 2 O 4 , which is less reactive than CaMnO 3 .…”

“…Reforming is one of the most important processes to produce hydrogen (H 2 ) and/or syngas (H 2 and CO), which can be further used in downstream processes [1][2][3]. Three main reactions widely studied in H 2 or syngas production from methane (CH 4 ) are partial oxidation, dry reforming, and steam reforming [4,5].…”

Kinetic Monte-Carlo Simulation of Methane Steam Reforming over a Nickel Surface

A kinetic Monte-Carlo model was developed in order to simulate the methane steam reforming and kinetic behavior of this reaction. There were 34 elementary step reactions that were used, based on the Langmuir–Hinshelwood mechanism, over a nickel catalyst. The simulation was investigated at a mole fraction of methane between 0.1 and 0.9, temperature of 600 to 1123 K, and total pressure of up to 40 bar. The simulated results were collected at a steady state and were compared with the previously reported experiments. The fractional coverages of the adsorbed species and the production rates of H2, CO, and CO2 were evaluated, and the effects of the reaction temperature, feed concentration, and total pressure of reactants were also investigated. The simulation results showed a similar trend with previous experimental results, and suggested the appropriate conditions for this reaction, which were a total pressure of 10 bar, with the mole fraction of methane in a range of 0.4–0.5.
