“…The emission rate depends on engine construction, plant design, and operation. Emissions can come from water handling facilities, gas engine exhausts, gas flaring, leaks from pipes, biogas upgrading units, tanks, etc., or from deliberate venting (Angelidaki et al, 2018;Duren et al, 2019;Fredenslund et al, 2018;Liebetrau et al, 2018;Samuelsson et al, 2018;Scheutz & Fredenslund, 2019). Some emissions can be single large leaks or long-lasting bursts from pressure relief valves (Reinelt & Liebetrau, 2019).…”

The atmospheric methane burden is increasing rapidly, contrary to pathways compatible with the goals of the 2015 United Nations Framework Convention on Climate Change Paris Agreement. Urgent action is required to bring methane back to a pathway more in line with the Paris goals. Emission reduction from “tractable” (easier to mitigate) anthropogenic sources such as the fossil fuel industries and landfills is being much facilitated by technical advances in the past decade, which have radically improved our ability to locate, identify, quantify, and reduce emissions. Measures to reduce emissions from “intractable” (harder to mitigate) anthropogenic sources such as agriculture and biomass burning have received less attention and are also becoming more feasible, including removal from elevated‐methane ambient air near to sources. The wider effort to use microbiological and dietary intervention to reduce emissions from cattle (and humans) is not addressed in detail in this essentially geophysical review. Though they cannot replace the need to reach “net‐zero” emissions of CO2, significant reductions in the methane burden will ease the timescales needed to reach required CO2 reduction targets for any particular future temperature limit. There is no single magic bullet, but implementation of a wide array of mitigation and emission reduction strategies could substantially cut the global methane burden, at a cost that is relatively low compared to the parallel and necessary measures to reduce CO2, and thereby reduce the atmospheric methane burden back toward pathways consistent with the goals of the Paris Agreement.

“…[35] Moreover, the process is facilitated by hydrogenotrophic methanogens, which are abundantm icroorganisms found in biogasp lants. One of the inherentadvantages is that the process occurs under mild temperature conditions (in the range of 30 to 60 8C, that is, meso or thermophilic) and close to atmospheric pressure.…”

“…Adsorption based processes have been widely explored for the upgrading of biogas due to their relatively low energy requirements and capital investment cost, flexibility of design, safety and simplicity of operation, as well as a high efficiency [6]. On this type of separation technology, the components of a gas mixture are separated based on their molecular characteristics and affinity to an adsorbent material.…”

Abstract:The aim of the present study is to provide new insights into the CO 2 and CH 4 adsorption using a set of biomass-based activated carbons obtained by physical and chemical activation of olive-stones. The adsorption behavior is analyzed by means of pure gas adsorption isotherms up to 3.2 MPa at two temperatures (303.15 and 323.15 K).The influence of the activation method on the adsorption uptake is studied in terms of both textural properties and surface chemistry. For three activated carbons the CO 2 adsorption was more important than that of CH 4 . The chemically activation resulted in higher BET surface area and micropore volume that lead to higher adsorption for both CO 2 and CH 4 . For methane the presence of mesopores seems to facilitate the access of the gas molecules into the micropores while for carbon dioxide, the presence of oxygen groups enhanced the adsorption capacity.
