High-pressure Methane Adsorption on Natural and Synthetic Zeolites

open access: yes, 1994
The adsorption isotherms of methane on synthetic (5A and 13X) and natural (Erionite) zeolites at different temperatures have been obtained through the use of a high-pressure volumetric adsorption apparatus over the pressure range 0–5 MPa.

Carbon Coking‐Tolerant Perovskite Catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 for Efficient Methane Dry Reforming

open access: yesCarbon and Hydrogen, EarlyView.
A new perovskite‐type catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 was developed for methane dry reforming, which exhibited 93.1% CH4 and 94.7% CO2 conversion with 100 h stability run and excellent anti‐coking capability, benefited from in situ exsolved Fe‐Ni alloy nanoparticles. ABSTRACT Perovskite with high temperature stability and tunability is a very promising

Modelling of physical and chemical properties of activated carbons which affect methane adsorption mechanisms

open access: yesPetroleum Research
Effect of important physical and chemical properties of activated carbons which affect the way methane adsorbs were studied. The Grand Canonical Monte Carlo (GCMC) simulations were used to study how the curvature and size of the platelets affect the ...

Pure and Binary Adsorption of Methane and Nitrogen by Silicalite

open access: yes, 2008
Methane is the most important non-CO2 greenhouse gas (GHG) responsible for global warming with more than 10 % of total GHG emissions. The greenhouse warming potential (GWP) of this gas is much higher than carbon dioxide.
