Electron Removal Processes in Proton-Methane Collisions

Physics Procedia, 2015
AbstractWe investigate electron removal processes in the proton-methane collision system in the 20 keV to a few MeV energy regime. The two-centre basis generator method is used within the independent electron model to study this problem. Results for net capture and ionization are compared with available experimental and theoretical studies as well as ...

Methane degradation in biotrickling filters: Recyclable materials as a support medium

Revista de Ciencias Agrícolas
Biofiltration is an alternative method for reducing methane, a greenhouse gas with public health risks and climate impacts. However, its feasibility is often limited by the high costs of organic beds and inadequate surface area.

Biological methane removal by groundwater trickling biofiltration for emissions reduction [PDF]

Water Research
Methane removal is an essential step in drinking water production from methane-rich groundwaters. Conventional aeration-based stripping results in significant direct methane emissions, contributing up to one-third of a treatment plant's total carbon footprint.

Economics of enhanced methane oxidation relative to carbon dioxide removal

Environmental Research Letters
Mitigating short-term global warming is imperative, and a key strategy involves reducing atmospheric methane (CH _4 ) due to its high radiative forcing and short lifespan.

Denitrification coupled with methane anoxic oxidation and microbial community involved identification

Brazilian Archives of Biology and Technology, 2011
In this work, the biological denitrification associated with anoxic oxidation of methane and the microbial diversity involved were studied. Kinetic tests for nitrate (NO3-) and nitrite (NO2-) removal and methane uptake were carried out in 100 mL batch ...

A review of prominent emerging technologies for atmospheric methane reduction

Discover Sustainability
Methane (CH4) concentration will unavoidably exceed zero, even though the Paris Climate Agreement (PCA) mandates a rapid reduction in new greenhouse gas emissions to achieve net zero by 2050.

Methane Emissions Offsetting With Temporary Carbon Sinks

GCB Bioenergy
Methane accounts for more than 20% of current anthropogenic warming. While fossil methane emissions can likely be reduced substantially, biogenic methane from agriculture and waste will remain difficult to fully abate.
