This article provides an overview of conventional and developing gas processing
technologies for CO2 and N2 removal from natural gas. We consider process technologies …

Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2),
but its global warming potential is 21–28 times that of CO2. Coal mining accounts for 9% of …

Pure gas adsorption isotherms of carbon dioxide at (273, 283, 303, 323, 343) K and binary
adsorption isotherms of carbon dioxide and methane at (303, 323) K and pressures up to 10 …

Activated carbon monoliths with hierarchical pore structures were prepared from petroleum
tar pitch and powdered coal in a low pressure foaming process with potassium hydroxide …

An experimental evaluation of the kinetics and equilibrium capacities of pure fluids as a fast
and effective means to screen an adsorbent's gas separation potential is described …

Activated carbon was evaluated as selective adsorbent for separation of CO2 from CO2/CH4
mixtures with special focus on high pressure applications. Adsorption equilibrium of pure …

Removal of carbon dioxide from natural gas for LNG production, can be carried out by
cryogenic distillation using a multicolumn sequence to obtain a product stream with less …

To implement an experimental study of CH4/N2 adsorption on Zeochem Co. zeolite 13X, a
volumetric apparatus was utilized. In this regard, pure adsorption isotherms were measured …

The separation of methane and nitrogen from binary mixtures using a commercial activated
carbon, Norit RB3, was investigated. The adsorption of pure fluids and CH4+ N2 mixtures …

The utilization of adsorption processes operating at low temperatures can be interesting in
the context of production of liquefied natural gas (LNG), where they can constitute a lower …
