In the present contribution, numerical experiments are used to interpret results obtained from physical diffusion-influenced for CO and CO2 co-methanation. Physical conducted in temperature range 513 573 K different CO/CO2 ratios. It is revealed that behave very differently when both simultaneously converted into CH4, which mainly due competing reaction kinetics. Since inhibits methanation of i...

The influence of the support basicity, according to Lewis and Brønsted definition, was investigated for CO2 methanation over isostructural Ru catalysts.

Methanation is capable of chemical storage fluctuating renewable energy, which requires fundamental understanding the dynamics kinetic processes taking place on catalyst surface. In order to elucidate impact support dynamics, Co-based model catalysts were synthesized via double flame spray pyrolysis (DFSP) differing only in materials. particular, Co nanoparticles identical particle size distrib...

Operando synchrotron powder X-ray diffraction deconvolutes support and metal nanoparticle changes during thermal deactivation of Ni/ZrO 2 methanation catalysts.

Catalytic conversion of CO2 into methane is an attractive method because it can alleviate global warming and provide a solution for the energy depletion crisis. Nickel-based catalysts were commonly employed in such conversions due to their high performance over cost ratio. However, major challenges are that Ni tends agglomerate cause carbon deposition during high-temperature reaction. In past d...

Ammonia (NH3) is produced from atmospheric nitrogen and hydrogen from a hydrocarbon source. Natural gas is the most commonly used hydrocarbon feedstock for new plants; other feedstocks that have been used include naphtha, oil, and gasified coal. Natural gas is favored over the other feedstocks from an environmental perspective. Ammonia production from natural gas includes the following processe...

In this study, it was aimed to develop new catalysts increase the conversion of environmentally harmful carbon dioxide gas methane which is a valuable fuel. By using natural clay mineral sepiolite (SEP) as support material; 6-8% (weight-weight) Ni-containing were prepared by impregnation. Catalysts characterized XRD and FT-IR analysis. Reaction conditions catalytic hydrogenation for production ...
