Synthetic Natural Gas (SNG) produced from renewable sources constitutes a solution for the transition to net-zero emissions natural gas relying sectors. From different biomass-to-SNG routes, gasification of biomass produce syngas that is further converted into SNG has large potential in near future. In this work, methanation process under quasi commercial conditions was demonstrated generated g...

Abstract CO 2 methanation is a promising technology to enable the use of as resource. Thermal control methanation, which highly active exothermic reaction, important avoid thermal runaway and subsequent degradation catalyst. Using heat storage capacity phase change material (PCM) for reaction novel passive approach. In this study structure was developed, wherein catalysts were directly loaded o...

Biological methanation of carbon dioxide using hydrogen makes it possible to improve the methane and energy content biogas produced from sewage sludge organic residuals reach requirements for injection into natural gas network. Biofilm reactors, so-called trickling bed offer a relatively simple, energy-efficient, reliable technique upgrading via ex-situ methanation. A mesophilic lab-scale biofi...

The present research focuses on a Ni-Mg-Al hydrotalcite-derived catalyst promoted with Cu. Catalysts were prepared by the co-precipitation method at constant pH and subsequently characterized via XRD, H2-TPR, CO2-TPD, TGA, XAS, TEM, low-temperature nitrogen sorption tested for CO2 hydrogenation to methane. methanation reaction was carried out GHSV of 12,000 ml?g-1 h-1 high selectivity (above 98...

Utilization of the renewable energy sources is one main challenges in state-of-the-art technologies for CO2 recycling. Here we have taken advantage solar light harvesting thermocatalytic approach to carbon dioxide methanation. The large-surface-area Ni/CeO2 catalyst produced by a scalable low-cost method was characterized and tested dark under irradiation conditions. Light-assisted conversion e...

Conclusions The application of the mixed monolayer approach to gold electrodes coated with highly organized long-chain hydrocarbon amphiphiles enables us a t this point to obtain complete blocking of the electrode, or, by controlling the adsorption conditions, to leave a certain amount of natural pinholes. Both cases are of considerable interest from an electrochemical point of view. In the pre...

In this work, we discuss the role of different atmospheres and process conditions on catalytic performances Ru- K/Ba-based dual-function materials (DFMs) for CO2 capture methanation. By a combination microreactor experiments Fourier transform infrared (FT-IR) spectroscopy, clarify effect temperature H2 partial pressure during hydrogenation step water oxygen adsorption step. particular, show tha...
