As renewable energy source integration increases, P2G technology that can store surplus power as methane is expected to expand. The development of a CO2 methanation catalyst, one the core processes concept, being actively conducted. In this work, low-rank coal (LRC) was used catalyst support for methanation, it potentially enhance diffusion and adsorption behavior by easily controlling pore str...

The performance of a novel reverse membrane bioreactor (RMBR) with encased microorganisms for syngas bio-methanation as well as a co-digestion process of syngas and organic substances was examined. The sachets were placed in the reactors and examined in repeated batch mode. Different temperatures and short retention time were studied. The digesting sludge encased in the PVDF membranes was able ...

The effect of Au in the behavior of Ru as a Fischer-Tropsch catalyst was studied. Two series of catalysts were investigated, one supported on Si02 and the other on MgO. Au did not seem to alter the product distribution on Ru at pressures up to 1 MPa and in the temperature range 490-570 K. However, the turnover frequencies for both CO hydrogenation and methanation showed a precipitous drop with ...

The technology of CO2-methanation has already been positioned as a Japanese national policy, and is highly effective in that existing natural gas city infrastructure can be used without change. INPEX promoting the development technology（400 Nm3-CO2/h）in our field NEDO project based on policy business goals.

Methanation of CO 2 is an important reaction for reducing emissions in a power-to-gas system. Compared to cobalt supported on gamma-Al O 3 , graphene nanoplatelets (GNPs) showed significantly better performance methanation. Cobalt GNPs was capable 15% conversion CH 4 at temperatures below 250°C, compared 5% Al . In situ thermogravimetric analysis (TGA) demonstrated that the Co/GNP catalyst stab...

Abstract Biogenic energy sources are essential elements of the decarbonization pathways, but strongly constrained by limited availability. In this context, Biogas&Power-to-X technologies supported as a promising solution to foster renewable power generation and drive sector coupling opportunities. This work investigates enhanced Synthetic Natural Gas (SNG) production processes for repurposi...

The Ni-based catalysts have a wide range of industrial applications due to its low cost, but activity CO2 methanation is not comparable that precious metal catalysts. In order solve this problem, mesoporous Ce0.8Zr0.2O2 solid solution doped with rare earth were prepared by the incipient impregnation method and directly used as for CO2. characterized systematically X-ray powder diffraction (XRD)...
