“…Yet, studies on the behavior of microbial consortia under different operating conditions still need to be conducted to improve our understanding of the microbial interactions within microbial consortia and achieve an optimal performance in microbial consortia‐driven processes. The effect of operational parameters such as pH, temperature, gas partial pressure and syngas impurities were recently reviewed in the frame of syngas fermentation to ethanol and other products . Thus, this review focuses on the progress made in the abovementioned aspects of syngas biomethanation processes over the last years, laying special emphasis on the role of microbial interactions within syngas‐converting mixed microbial consortia.…”

Signifi cant research efforts are currently being made worldwide to develop more effi cient biomethane production processes from a variety of waste streams. The biomethanation of biomassderived syngas can contribute to increasing the potential of methane production as it opens the way for the conversion of recalcitrant biomasses, generally not fully exploitable by anaerobic digestion systems. Additionally, this biological process presents several advantages over its analogous process of catalytic methanation such as the use of inexpensive biocatalysts, milder operational conditions, higher tolerance to the impurities of syngas, and higher product selectivity. However, there are still several challenges to be addressed for this technology to reach commercial stage. This work reviews the progress made over the last few years in syngas biomethanation processes in order to provide an overview of the current state of the art of this technology. The most relevant aspects determining the performance of syngas biomethanation processes are extensively discussed here, including microbial diversity and metabolic interactions in mixed microbial consortia, the infl uence of operating parameters and bioreactor designs, and the potential of modelling as a tool for the design and control of this bioprocess.

“…The gasification process here considered was based on the technology described by the NREL, which produces ‐syngas suitable for fermentation. Such a process configuration returns low dilution of fermentable gases, and produces high carbon conversion into CO while keeping low CO 2 concentrations and maintains CH 4 as low as ‐possible . The process takes place at atmospheric pressure and uses three fluidized bed reactors, as shown in Fig.…”

This study presents the design and assessment of site‐specific supply chains and related manufacturing processes for the production of bio‐based chemicals from the syngas platform and via gasification of lignocellulosic biomass followed by syngas fermentation. The supply chains include feedstocks production and collection, biomass gasification, syngas fermentation, and downstream processing. For each of these stages, different alternatives were considered: four feedstocks (pine, corn stover, sugarcane bagasse, and eucalyptus), three products (ethanol, 2,3‐butanediol and hexanoic acid), and three geographical locations (the Netherlands, the USA, and Brazil). Conceptual development and analysis of the supply chains were done through the combination of different design and assessment tools, namely biomass supply chains design, fermentation process design (based on thermodynamics and transport), process simulation, and economic and environmental assessments. The minimum selling price (MSP) and two environmental impact categories, i.e., global warming potential (GWP) and non‐renewable energy use (NREU), were used as performance indicators. These were compared to data reported in scientific literature and commercial sources for similar processes and products. The best overall performance was obtained for the production of 2,3‐butanediol from pine sourced in the USA. In the cases of ethanol and hexanoic acid, the syngas fermentation stage had significant contributions to MSP, GWP, and NREU, due mainly to its high energy requirements. Regarding the geographical location, the best economic performance was obtained for the USA followed by the Netherlands and Brazil respectively. Furthermore, operation in Brazil led to the lowest environmental impacts, followed by the Netherlands and the USA. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd

Selective and Direct Hydrogenation of CO₂ for the Synthesis of Formic Acid over a Rhodium Hydrotalcite (Rh‐HT) Catalyst

et al. 2017

Rhodium hydrotalcite (Rh‐HT), a heterogeneous catalyst was synthesized, characterized and investigated for CO2 hydrogenation. The catalyst was effectual for the CO2 hydrogenation and selective formation of formic acid at a moderate temperature and was efficiently recycled up to 5 times without any significant loss in activity. A TON of 15840 for formic acid was selectively obtained at 50 bar pressure (1:1, p/p, CO2 and H2) and 60 °C temperature in a mixture of methanol:water (5:1 v/v, 60 mL) as a solvent in 24 h with no additional base. The effect of various reaction parameters was investigated for the reaction rate and CO2 conversion. The formic acid formation rate follows the 1st order kinetic trend regarding the catalyst amount and partial pressure. The determined activation parameters from the temperature dependence rate of formic acid were Ea=33.5 ± 2.5 kJmol−1, ΔH#=30.9 ± 2.5 kJmol−1, ΔS#=‐275 ± 5 Jdeg−1mol−1. The presence of water as a solvent together with methanol have effectively enhanced the performance of the catalyst. The mechanistic routes for CO2 hydrogenation to formic acid are proposed and discussed by the kinetic and experimental observations.
