In this review, conventional biogas upgrading technologies, including physical absorption, chemical absorption, adsorption, and membrane technologies, are evaluated in terms of …
Biogas–a renewable energy source encompassing primarily CO 2/CH 4 mixture, can fuel vehicles if it is properly purified. Recently, cryogenic biogas upgrading (CO 2 Liquefaction) …
CO2 emissions from industrial processes and their adverse implications on the climate is of major concern. Carbon capture and storage (CCS), especially using chemical-absorption …
The production of syngas (ie, a mixture of CO and H2) via the electrochemical reduction of CO2 and water can contribute to the green transition of various industrial sectors. Here we …
In this paper, ideas for improving the cryogenic separation of CO 2/CH 4 mixture are drawn in order to upgrade biogas to biomethane, matching natural gas standards. On this basis, a …
Biogas has emerged as an alternative renewable fuel to natural gas. However, the presence of trace contaminants and large quantities of CO 2 in biogas necessitates its purification and …

This paper proposes a novel power and methanol cogeneration due to biogas upgrading, liquefied natural gas cooling, and natural gas combined reforming. The proposed process …
Amine-absorption and pressure swing adsorption (PSA) technologies have been regarded as attractive methods to upgrade biogas by separating acid gases such as CO 2 and H 2 S …
Biogas is a promising renewable energy source that is produced from biowaste and can potentially replace conventional energy resources. The economic value of biogas, which is …
