Separation of mixture is always necessarily required in modern industry, especially in fine
chemical, petrochemical, coal chemical and pharmaceutical industries. The challenge of the …

In today's perspective, natural gas has gained considerable attention, due to its low
emission, indigenous availability, and improvement in the extraction technology. Upon …

Coal mine methane (CMM) with the worldwide reserves of 2.6× 1014 m3 is one of the
important unconventional natural gases. However, most of the low-concentration coal mine …

A novel compact adsorption-based process for removal of carbon dioxide and nitrogen from
low and medium natural gas flowrates is discussed. The layered pressure swing adsorption …

The rapid increase of natural gas consumption has induced imbalance between supply and
demand of natural gas, and the continuous growth of methane emissions has severely …

This review focuses on the mechanism and driving force in the intractable gas separation
using porous adsorbents. A variety of intractable mixtures have been discussed, including …

In this study, the adsorption capacity of the low-cost zeolite clinoptilolite was investigated for
capturing carbon dioxide (CO 2) emitted from industrial processes at moderate temperature …

Hydrogen is an important energetic vector nowadays. The most common industrial method
to produce ultrapure hydrogen is by steam methane reforming (SMR), where hydrogen is …

Two types of CHA zeolite membranes (SAPO-34, SSZ-13) were used for CO 2/CH 4, N 2/CH
4, and CO 2/i-butane separations at both low (270 and 350 kPa) and high (1.73 MPa) …

Natural gas is one of the critical fossil fuel sources in the world to fulfill current energy
demand in the global market. Methane is the primary component in natural gas and its …
