Characteristic modification of coal-based activated carbon and its methane adsorption capacity
工程科学学报, 2022 Methane is an important high-quality clean energy that mainly comes from the decomposition of organic waste, natural gas, fossil fuel extracts, etc. Recycling it from a gaseous mixture is beneficial for environmental protection and energy utilization and

Comprehensive Review about Methane Adsorption in Shale Nanoporous Media [PDF]
, 2021 Shale/tight gas plays an increasingly important role to meet the growing global energy demand and reduce carbon emissions. Unlike conventional reservoirs, shale formations are subject to rock heterogeneity and have pore size distributions ranging from ...

Molecular Simulation of the Adsorption of Methane in Engelhard Titanosilicate Frameworks [PDF]
Langmuir, 2014 Molecular simulations were carried out to elucidate the influence of structural heterogeneity and of the presence of extra-framework cations and water molecules on the adsorption of methane in Engelhard titanosilicates, ETS-10 and ETS-4. The simulations employed three different modeling approaches, (i) with fixed cations and water at their single ...

Upgrading of Biogas to Methane Based on Adsorption [PDF]
Processes, 2020 Upgrading raw biogas to methane (CH4) is a vital prerequisite for the utilization of biogas as a vehicle fuel or the similar field as well. In this work, biogas yield from the anaerobic fermentation of food waste containing methane (CH4, 60.4%), carbon dioxide (CO2, 29.1%), hydrogen sulfide (H2S, 1.5%), nitrogen (N2, 7.35%) and oxygen (O2, 1.6%) was ...
