“…Adsoprtion-based removal of CO 2 from biogas is widely practiced and commercially applied at both pilot and demonstration plant levels and is still an active research subject (Cavenati et al, 2008;Cebula, 2009;Petersson and Wellinger, 2009;Alonso-Vicario et al, 2010;Tippayawong and Thanompongchart, 2010;Grande, 2011;Montanari et al, 2010;Grande, 2012;Ryckebosch et al, 2011;Yuan et al, 2013;Andriani et al, 2014). The techniques used include PSA and TSA, both involving two packed-bed columns in a swing-type arrangement employing appropriate valve sequencing, as shown schematically in Figure 2.…”

“…This must be appropriately determined in order to allow continuous utilization of the feedstream with continuous production of CH 4 in the system's exhaust. The basic concept can be varied, especially in regard to the number of steps required for a complete cycle, and with respect to the operating sequence of the valves during each step (Grande, 2012). In addition to CH 4 -CO 2 separation, the concept has been successfully applied in a number of other separations, for example in the purification of H 2 -containing streams for fuel cell applications (Nikolaidou et al, 2015); for C 2 H 4 separation from CH 4 and O 2 in the oxidative coupling of methane, thus providing a one-step transformation of methane to ethylene with extremely high yields (Jiang et al, 1994); for air separation (Jee et al, 2001); for noble gas purification (Das et al, 2008); for n-paraffin/iso-paraffin separation (Yang, 2003), and others.…”

Biogas is widely available as a product of anaerobic digestion of urban, industrial, animal and agricultural wastes. Its indigenous local-base production offers the promise of a dispersed renewable energy source that can significantly contribute to regional economic growth. Biogas composition typically consists of 35-75% methane, 25-65% carbon dioxide, 1-5% hydrogen along with minor quantities of water vapor, ammonia, hydrogen sulfide and halides. Current utilization for heating and lighting is inefficient and polluting, and, in the case of poor quality biogas (CH 4 /CO 2 < 1), exacerbated by detrimental venting to the atmosphere. Accordingly, innovative and efficient strategies for improving the management and utilization of biogas for the production of sustainable electrical power or high added-value chemicals are highly desirable. Utilization is the focus of the present review in which the scientific and technological basis underlying alternative routes to the efficient and eco-friendly exploitation of biogas are described and discussed. After concisely reviewing state-of-the-art purification and upgrading methods, in-depth consideration is given to the exploitation of biogas in the renewable energy, liquid fuels, transport and chemicals sectors along with an account of potential impediments to further progress.Keywords: biogas, upgrading, purification, utilization, SOFC, ethylene, reforming, siloxanes BIOGAS Efficient management of ever-increasing amounts of municipal, industrial and agricultural wastes in order to minimize their environmental impact is an urgent necessity. Biological treatment of wastes, which can be carried out either aerobically or anaerobically, is widely applied in this area. Due to their several advantages the anaerobic processes are to be preferred because they require considerably smaller installations, produce less sludge, operate at lower temperatures and are suited to periodic operation. Much more importantly, they generate biogas, which is an attractive potential source of renewable energy and/or added-value chemicals due to its high content of methane and CO 2 . Anaerobic digestion (AD) can proceed over a wide temperature range, from phychrophilic (ca. 10-20 • C) and mesophilic (ca. 20-45 • C) up to thermophilic (ca. 45-65 • C) and hyperthermophilic (ca. ∼70 • C) levels, by means of cooperation between anaerobes and facultative anaerobe microorganisms, which successively promote a sequence of hydrolysis-acidogenesis,

Molecular simulations have been employed to explore at the microscopic scale the adsorption of CO in zeolites (MFI, CHA and DDR). On the basis of classical force fields, grand canonical Monte Carlo simulations are performed to predict the adsorption properties (isotherms) of these types of zeolites up to high pressure. Subsequent careful analysis yields details the microscopic mechanism in play, along the whole adsorption process, together with a considering of the arrangements of CO in MFI at high pressure. This work also summarizes an approach which uses single component diffusion data in prediction of multicomponent diffusion.

“…TSA process generally produce a humid stream of pure CO2 which will require drying before it can be stored or utilized as an intermediate; this drying step is also very energy intensive. More recent research into pressure swing adsorption (PSA) for CO2 capture using solid sorbents has generated promising results (Ho et al, 2009;Wang et al, 2011;Grande, 2012). PSA has many advantages over traditional systems in that it has a much smaller plant footprint, can accept changing feed compositions and is a stop-start technology making it very flexible with regard to the plant that is supplying it.…”

Integrated CO2 Capture and Utilization Using Non-Thermal Plasmolysis

et al. 2017

In this work, two simple processes for carbon dioxide (CO2) such as capture and utilization have been combined to form a whole systems approach to carbon capture and utilization (CCU). The first stage utilizes a pressure swing adsorption (PSA) system, which offers many benefits over current amine technologies. It was found that high selectivity can be achieved with rapid adsorption/desorption times while employing a cheap, durable sorbent that exhibits no sorbent losses and is easily regenerated by simple pressure drops. The PSA system is capable of capturing and upgrading the CO2 concentration of a waste gas stream from 12.5% to a range of higher purities. As many CCU end processes have some tolerance toward impurities in the feed, in the form of nitrogen (N2), for example, this is highly advantageous for this PSA system since CO2 purities in excess of 80% can be achieved with only a few steps and minimal energy input. Nonthermal plasma is one such technology that can tolerate, and even benefit from, small N2 impurities in the feed, therefore a 100% pure CO2 stream is not required. The second stage of this process deploys a nanosecond pulsed corona discharge reactor to split the captured CO2 into carbon monoxide (CO), which can then be used as a chemical feedstock for other syntheses. Corona discharge has proven industrial applications for gas cleaning and the benefit of pulsed power reduces the energy consumption of the system. The wire-in-cylinder geometry concentrates the volume of gas treated into the area of high electric field. Previous work has suggested that moderate conversions can be achieved (9%), compared to other non-thermal plasma methods, but with higher energy efficiencies (>60%).
