Methanation in a fluidized bed reactor with high initial CO partial pressure: Part II— Modeling and sensitivity study

CO methanation over TiO2-supported nickel catalysts: A carbon formation study

“…Methanation is a key step in the production of SNG and great efforts are made in the development of efficient catalysts [9][10][11][12][13][14] and reactor systems [15][16][17][18][19][20]. Among all the materials which catalyze the methanation reaction, nickel-based catalysts are preferred due to their high activity, selectivity towards methane and relatively low cost [21,22].…”

Methanation for Synthetic Natural Gas Production – Chemical Reaction Engineering Aspects

“…The total bulk flow from the bubble to the dense phase  N vc (that compensates for the volume contraction of the reactions) is described as the sum of the molar losses due to the reaction and mass transfer in the dense phase [150]. The total bulk flow from the bubble to the dense phase  N vc (that compensates for the volume contraction of the reactions) is described as the sum of the molar losses due to the reaction and mass transfer in the dense phase [150].…”

Influence of vertical internals on a bubbling fluidized bed characterized by X-ray tomography

“…Those correlations generally provide mean values of bubble size, velocity and hold-up and are used for the development of computer models, such as the two-phase model Toomey and Johnstone (1952) and Kopyscinski et al (2011). To describe the hydrodynamic properties of bubbling fluidized bed reactors with vertical internals, none of the existing correlations seem appropriate, and reliable data is rarely found in the open literature Rüdisüli et al (2012b).…”
