Three different power-to-methane process chains with grid injection in two scales (1 MW el and 6 ) were analysed regarding their investment operation cost. The based on biological or catalytic bubbling fluidised bed methanation combination proton exchange membrane solid oxide electrolyser cells. A bottom-up techno-economic analysis showed a cost benefit of around 17–19% lower biomethane product...

The need to reduce the concentration of CO2 in atmosphere is becoming increasingly necessary since it considered main factor responsible for climate change. Carbon Capture and Utilization (CCU) technology offers opportunity obtain a wide range chemicals using this molecule as raw material. In work, catalytic Non-Thermal Plasma (NTP)-assisted hydrogenation CH4 (methanation reaction) Dielectric B...

irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. this experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (k) with that of di...

CO selective methanation (CO-SMET) is a promising method for deep removal from H2-rich gases. In this study, series of RuNi/MMO catalysts are prepared using the support MMO-N derived NiAl-NO3-LDHs, which was NiAl-CO3-LDHs via an acid–alcohol ion-exchange reaction. The were characterized by XRD, SEM, TEM, XPS, H2-TPR, CO-TPD, CO2-TPD, NH3-TPD, and TG. RuNi/MMO-N catalyst demonstrated excellent C...

In the context of climate change mitigation, CO2 methanation is an important option for production synthetic carbon-neutral fuels and atmospheric recycling. While being highly exothermic, this reaction kinetically unfavorable, requiring a catalyst to be efficiently activated. Recently Rh nanoparticles gained attention as effective photocatalyst, but rate-determining step on surface has not been...

The production of synthetic natural gas (SNG) via methanation has been demonstrated by experiments in bench scale bubbling fluidized bed reactors. In the current work, we focus on scale-up reactor, and a circulating (CFB) is designed with variable diameter according to characteristic methanation. critical issue removal reaction heat during strongly exothermic process As result, an interconnecte...
