Techno-economic evaluation of a biogas-based oxidative coupling of methane process for ethylene production

Tuning Gate‐Opening of a Flexible Metal–Organic Framework for Ternary Gas Sieving Separation

“…Thei ndustrial mixtures generally contain 1% of C 2 H 2 and up to about 30 %o fCO 2 . [10,25] We therefore altered the mixture ratios by tuning CO 2 percentage and kept C 2 H 2 /C 2 H 4 ratio of 1:99. As shown in the Supporting Information, Figure S39 and S40, C 2 H 4 /C 2 H 2 /CO 2 mixtures with volume ratio of 95.7:0.967:3.33 (v/v/v) and 66.00:0.67:33.33 (v/v/v) can be separated by NTU-65 yielding pure C 2 H 4 .L ow percentage of CO 2 can be efficiently captured.…”

An economic analysis of twenty light olefin production pathways

“…The anaerobic digestion of biomass by methane-genic bacteria could produce biogas, which consists of methane (50%-70%) and CO 2 (30%-50%) with small amounts of water, H 2 S, and others [20] . The impurities, especially sulfur and silicone derived compounds, were required to be removed from biogas through activated carbon adsorption [42] .…”

“…Furthermore, techno-economic analysis (TEA) of renewable pathways has been studied. With vinasse as feedstock, Penteado et al [20] reported that the project integrating anaerobic digestion to biogas, biogas upgrade, and OCM processes to produce ethylene is profitable. While TEA of ethylene production via bioethanol dehydration with different sources revealed that not all scenarios enable the cost-competitive production of ethylene at current market prices [15 , 21] .…”

Contributions in renewable energy systems: A perspective from the latest publications of FCSE

“…An effort has been made by Mao et al [14] that upgrades the pyrolysis of bio-fuel from corncobs via integrating a zeolite-coated cordierite honeycomb into a bubbling fluidized bed pyrolyzer. Biogas is always a research focus for linking the renewable energy and the chemical engineering among the published works in FCSE, i.e., a techno-economic assessment was carried out for generating biogas-based ethylene via oxidative coupling with methane [15]; the technical and economic feasibility of bio-methane plant with combined heat and power units was verified by Saracevic et al [16]; while the possibility of using stabilized sewage sludge to produce methane-based biogas was also discussed [17]. Besides, biomass fermentation has been regarded as a promising way for the bio-energy production, such as ethanol from the fermentation of corn stover [18], and hydrogen from the dark fermentation of raw cassava starch [18].…”
