The comparison study of 1D, 2D and 3D models on steam methane reforming is performed for same CFD-code, initial conditions, catalyst type, approximation scheme, the convergence criteria, the turbulence model, the type of solution initialization.
Alastair Lewis, an atmospheric chemist at the University of York in the United Kingdom, who has worked alongside Hewitt on different projects, points out that the finding has implications for climate modeling of methane, another important greenhouse gas.
The proposed model is based on a combination of simple turbulent mixing approach with a detailed chemistry sub-model for methane oxidation and NO x formation.
Based on realistic kerogen model, the effects of water content on methane (CH4) adsorption capacity were studied qualitatively and quantitatively using the molecular dynamics (MD) and Monte Carlo (MC) simulation methods.
This ATR reactor model is able to describe the influence of temperature on methane conversion profiles, aiming to maximize hydrogen production.

The order on methane and steam obtained through power-law model were 0.94 and −0.16, respectively, where the negative order on steam clearly indicates that steam competes for the active sites which are the precursor for methane decomposition [22], and Model 7 representing a single-site was consistent with this finding (Fig. 8).
The overall high use of methane as a carbon source by both symbiont-bearing and heterotrophic fauna suggests that New Zealand methane seeps are an ideal model system to study the interaction among metazoans, bacteria, archaea, and their resulting effect on methane cycles.
The model was then used to investigate the effect of several key sewer design and operational parameters on methane formation.
The objective of this study was to determine the effect of dietary fiber on methane (CH4) production in pigs using the Chinese native Lantang gilts as study model.
