Analysis of biogas production from grass silage, depending on its quality

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
This article (work) gives information about production of methane from 11 samples of grass silage. Production was studied in two following levels: specific methane production per 1 kg of organic total solids, specific methane production per 1 kg of fresh

Declining methane emissions and steady, high leakage rates observed over multiple years in a western US oil/gas production basin

Scientific Reports, 2021
Methane, a potent greenhouse gas, is the main component of natural gas. Previous research has identified considerable methane emissions associated with oil and gas production, but estimates of emission trends have been inconsistent, in part due to ...

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

Advanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...
