    Solid oxide electrolysers (SOECs) are a key class of technology that offers an efficient solution to storing renewable energy. One of the key characteristics of this technology is its ability to reduce both H2O and CO2. Currently, commercial cells are adapted from those made for power generation (i.e. SOFCs) and are not suitable for generating gas of higher quality than syngas due to the limited behaviour of the cells. Electrochemical analyses and gas chromatography were used to examine the ability of SOEC cells to improve gas quality. With the addition of a functional layer to the cathode, we achieved a complementary effect between electrochemical mechanisms taking place at the cathode and catalytic mechanisms involving CO2 and CO methanation. In spite of the fact that the results could be significantly improved, this approach demonstrated the potential for CO2 and H2O co-electrolysis at intermediate temperatures.

    Solid oxide fuel cell (SOFC) is a mature opportunity for producing power energy in remote areas like islands, where access to the electrical grid is not favoured, and gas distribution is the only viable approach. In this context, generally, biogas represents the most convenient fuel resources in these areas. However, the direct use of biogas in SOFCs is still an issue to be solved due to its negative effect on the conventional Ni-YSZ anode. In this study, to overcome this issue, we suggested using a protective layer coated on the anode of a commercial SOFC. A nickel manganite showing mixed ionic and electronic conductivity tailored specifically for this approach was investigated. The preliminary characterisations showed that the formation of a Ruddlesden-Popper (RP) n ¼ 1 structure supporting fine encapsulated particles based on Ni was formed around 800 C in consequence of the reducing environment. The electrochemical experiments carried out for 270 h demonstrated for the coated cell significant stability in the presence of dry biogas, albeit an ageing effect was noticed in the electrical percolation of both cell electrodes. The post mortem analyses revealed an attractive redox property for the nickel manganite, which partially returned to the RP n ¼ 2 phase. Moreover, the absence of carbon deposits on the anode suggests possible applications for this approach.

    This research focused primarily on the process optimization for bio-oil production in a pilot-scale batch reactor operating in a fixed bed and using two important agricultural residues from Santander Department in Colombia: sugarcane bagasse (SB) and palm empty fruit bunch (EFB). The Simplex method was applied to develop experimental tests in which three main variables were studied: temperature, gas residence time and particle size. The choice of such variables was based on literature review suggesting that they have a major influence on bio-oil yield. The ranges of the operating conditions were: temperature 460–600 °C, gas residence time 16–80 s and particle size 0.5–1.4 mm. The analysis of variance (ANOVA) shows the temperature being the most influential variable on the bio-oil yield. The other variables were not significant for bio-oil production from intermediate pyrolysis. In the case of SB, the best operating conditions (temperature 560 °C, gas residence time 77 s and particle size 0.5–0.85 mm) resulted in a bio-oil yield of 53.4 wt%, whereas in the case of EFB, the best operating conditions (temperature 540 °C, gas residence time 31 s and particle size <0.5 mm) resulted in a bio-oil yield of 48.4 wt%. However, the physical–chemical properties of bio-oil stemming from the two studied biomasses are completely different, where the bio-oil from EFB presents the best HHV of 34.91 MJ/kg, the highest pH (3.9) and the lowest density (approximately 958 kg/m3).

    Bio-oil is a mixture of nearly 300 types of organic compounds, including phenols. Phenols are produced during oil refinement and are usually used as fuel additives, food antioxidants and in the synthesis of other chemicals. This study is mainly focused on the extraction of phenolic compounds from bio-oil produced during the pyrolysis of agroindustrial wastes. Bio-oil samples were produced by intermediated pyrolysis of oil from palm empty fruit bunch at 578 °C for 45.6 s using a fixed bed reactor. Under these conditions, the phenol fraction was 13.14 wt%. Two different extraction methodologies were used to obtain a higher phenol fraction of bio-oil: liquid–liquid extraction and reactive extraction. In the first method, an initial liquid–liquid extraction was performed to solubilize the bio-oil in a liquid phase. A second liquid–liquid extraction was subsequently performed with three different organic solvents to maximize the phenolic composition of the fraction. In contrast, the reactive extraction methodology was performed using a NaOH solution to produce phenolates, which are more soluble in water, and thus favor phenol extraction. The resulting phenol extraction yields were not higher than 30 wt% (i.e., a ratio of 1:3.5 of bio-oil and NaOH solution) for the reactive extraction; in contrast, for the liquid–liquid extraction, these yields rose above 68 wt%. The operating conditions favoring this extraction yield included a first extraction with a 5:1 dichloromethane/bio-oil mixture followed by a second extraction with a 10:1 ethyl acetate/concentrated dichloromethane bio-oil mixture.

    Due to the high operating temperatures required by commercially available cells, solid oxide electrochemical devices are currently limited in their application to sectors ranging from production to storage of energy, from pollution abatement to pure oxygen distillation. In this study, it is presented a novel electrolyte that promises to dramatically reduce the operating temperature of solid oxide electrochemical devices. Our proposed electrolyte consists of four cations and non-critical raw materials with a stoichiometry that allows for maximum entropy in an ABO3-based oxide. Preliminary results presented in this proceeding indicate that the material outperforms commercial cerates and zirconates in terms of thermal and electrochemical properties, while there is still room for further improvements.

    Solid oxide fuel cell (SOFC) is a mature opportunity for producing power energy in remote areas like islands, where access to the electrical grid is not favoured, and gas distribution is the only viable approach. In this context, generally, biogas represents the most convenient fuel resources in these areas. However, the direct use of biogas in SOFCs is still an issue to be solved due to its negative effect on the conventional Ni-YSZ anode. In this study, to overcome this issue, we suggested using a protective layer coated on the anode of a commercial SOFC. A nickel manganite showing mixed ionic and electronic conductivity tailored specifically for this approach was investigated. The preliminary characterisations showed that the formation of a Ruddlesden-Popper (RP) n ¼ 1 structure supporting fine encapsulated particles based on Ni was formed around 800 C in consequence of the reducing environment. The electrochemical experiments carried out for 270 h demonstrated for the coated cell significant stability in the presence of dry biogas, albeit an ageing effect was noticed in the electrical percolation of both cell electrodes. The post mortem analyses revealed an attractive redox property for the nickel manganite, which partially returned to the RP n ¼ 2 phase. Moreover, the absence of carbon deposits on the anode suggests possible applications for this approach.

    This research focused primarily on the process optimization for bio-oil production in a pilot-scale batch reactor operating in a fixed bed and using two important agricultural residues from Santander Department in Colombia: sugarcane bagasse (SB) and palm empty fruit bunch (EFB). The Simplex method was applied to develop experimental tests in which three main variables were studied: temperature, gas residence time and particle size. The choice of such variables was based on literature review suggesting that they have a major influence on bio-oil yield. The ranges of the operating conditions were: temperature 460–600 °C, gas residence time 16–80 s and particle size 0.5–1.4 mm. The analysis of variance (ANOVA) shows the temperature being the most influential variable on the bio-oil yield. The other variables were not significant for bio-oil production from intermediate pyrolysis. In the case of SB, the best operating conditions (temperature 560 °C, gas residence time 77 s and particle size 0.5–0.85 mm) resulted in a bio-oil yield of 53.4 wt%, whereas in the case of EFB, the best operating conditions (temperature 540 °C, gas residence time 31 s and particle size <0.5 mm) resulted in a bio-oil yield of 48.4 wt%. However, the physical–chemical properties of bio-oil stemming from the two studied biomasses are completely different, where the bio-oil from EFB presents the best HHV of 34.91 MJ/kg, the highest pH (3.9) and the lowest density (approximately 958 kg/m3).

    Bio-oil is a mixture of nearly 300 types of organic compounds, including phenols. Phenols are produced during oil refinement and are usually used as fuel additives, food antioxidants and in the synthesis of other chemicals. This study is mainly focused on the extraction of phenolic compounds from bio-oil produced during the pyrolysis of agroindustrial wastes. Bio-oil samples were produced by intermediated pyrolysis of oil from palm empty fruit bunch at 578 °C for 45.6 s using a fixed bed reactor. Under these conditions, the phenol fraction was 13.14 wt%. Two different extraction methodologies were used to obtain a higher phenol fraction of bio-oil: liquid–liquid extraction and reactive extraction. In the first method, an initial liquid–liquid extraction was performed to solubilize the bio-oil in a liquid phase. A second liquid–liquid extraction was subsequently performed with three different organic solvents to maximize the phenolic composition of the fraction. In contrast, the reactive extraction methodology was performed using a NaOH solution to produce phenolates, which are more soluble in water, and thus favor phenol extraction. The resulting phenol extraction yields were not higher than 30 wt% (i.e., a ratio of 1:3.5 of bio-oil and NaOH solution) for the reactive extraction; in contrast, for the liquid–liquid extraction, these yields rose above 68 wt%. The operating conditions favoring this extraction yield included a first extraction with a 5:1 dichloromethane/bio-oil mixture followed by a second extraction with a 10:1 ethyl acetate/concentrated dichloromethane bio-oil mixture.

    Due to the high operating temperatures required by commercially available cells, solid oxide electrochemical devices are currently limited in their application to sectors ranging from production to storage of energy, from pollution abatement to pure oxygen distillation. In this study, it is presented a novel electrolyte that promises to dramatically reduce the operating temperature of solid oxide electrochemical devices. Our proposed electrolyte consists of four cations and non-critical raw materials with a stoichiometry that allows for maximum entropy in an ABO3-based oxide. Preliminary results presented in this proceeding indicate that the material outperforms commercial cerates and zirconates in terms of thermal and electrochemical properties, while there is still room for further improvements.
