Post-combustion carbon dioxide (CO 2) capture via flue gas is an advanced technology for
mitigating greenhouse gas emissions. Its significance lies in the potential for retrofitting this …

Biogas consists of mainly methane, as a source of energy, and impurities such as carbon
dioxide, hydrogen sulphide, water, and siloxanes. These impurities, such as hydrogen …

This study presents a novel approach to optimize the anaerobic digestion of palm oil mill
effluent (POME) for maximum biogas production on an industrial scale. Unlike most …

The effect of carbon-coated zero-valent iron nanoparticles (NPs) on the upgrading of biogas
based on bacterial-algal symbiosis was assessed in an indoor pilot scale algal open pond …

The use of bio-methane as a fuel is an important alternative to reduce the emission of
greenhouse gases. Pressure swing adsorption (PSA) processes using carbon molecular …

In this study, simultaneous production of hydrogen and carbon nanotubes from direct
conversion of biogas is experimentally investigated. A series of monometallic Fe, Co, and Ni …

The existence of CO2 in biogas limits its utilization in engines by lowering its energy value
and density. It contributes to global warming which is a major concern globally. The …

Biogas upgrading aims to increase the methane concentration in biogas by removing
carbon dioxide. Upgraded biogas can then be used as a renewable energy resource …

Three different nanoparticles, namely Fe 2 O 3, carbon coated zero valent iron (CACOI) and
SiO 2, were added to a mixed microalgae culture in order to improve photosynthetic biogas …

In recent years, the use of biogas as a natural gas substitute has gained great attention.
Typically, in addition to methane (CH4), biogas contains carbon dioxide (CO2), as well as …
