Anaerobic Digestion as a Carbon Capture, Storage, and Utilization Technology

Chemical Engineering Transactions, 2022
It is expected that European biogas production will double by 2030 and quadruple by 2050. There are currently more than 18,943 biogas plants operating in Europe. With the emergence of biogas upgrading technologies, biogas is upgraded into biomethane with

Synthesis of Novel Heteroatom-Doped Porous-Organic Polymers as Environmentally Efficient Media for Carbon Dioxide Storage

Applied Sciences, 2019
The high carbon dioxide emission levels due to the increased consumption of fossil fuels has led to various environmental problems. Efficient strategies for the capture and storage of greenhouse gases, such as carbon dioxide are crucial in reducing their

Selected breakpoints of net forest carbon uptake at four eddy-covariance sites

Tellus: Series B, Chemical and Physical Meteorology, 2021
Extensive studies are available that analyse time series of carbon dioxide and water flux measurements of FLUXNET sites over many years and link these results to climate change such as changes in atmospheric carbon dioxide concentration, air temperature ...

The differential ability of two species of seagrass to use carbon dioxide and bicarbonate and their modelled response to rising concentrations of inorganic carbon

Frontiers in Plant Science, 2022
Seagrass meadows are one of the most productive ecosystems on the planet, but their photosynthesis rate may be limited by carbon dioxide but mitigated by exploiting the high concentration of bicarbonate in the ocean using different active processes ...

Uptake of Carbon Dioxide, Hydrogen and Oxygen by Hydrogenomonas facilis [PDF]

Journal of General Microbiology, 1952
The simultaneous uptake of CO2, H2, and O2 by non-proliferating cells of Hydrogenomonas facilis was studied by means of a new method employing ordinary Warburg vessels each provided with one stopper side-arm and one vent side-arm. H. facilis effected the same overall reaction as that carried out by certain anaerobically adapted green algae: 6H2 + 2O2 +

Catalyst Deactivation Simulation Through Carbon Deposition in Carbon Dioxide Reforming over Ni/CaO-Al2O3 Catalyst [PDF]

, 2011
Major problem in CO2 reforming of methane (CORM) process is coke formation which is a carbonaceous residue that can physically cover active sites of a catalyst surface and leads to catalyst deactivation.

Projected reversal of oceanic stable carbon isotope ratio depth gradient with continued anthropogenic carbon emissions

Communications Earth & Environment, 2022
Uptake of 13C-depleted anthropogenic carbon dioxide in the surface ocean may eliminate or reverse the natural vertical gradient in the isotopic composition of dissolved inorganic carbon in the ocean, analogous to events at the Paleocene-Eocene Thermal ...
