COMETTM ‐ A New Ventilation Air Methane (VAM) Abatement Technology

Thermal oxidation of coal mine ventilation air methane

Methane is a powerful greenhouse gas and the principal component of natural gas. Coal seams often contain significant quantities of methane, and underground coal mines must ensure that methane released into the mine during coal extraction does not build to dangerous levels. This is accomplished in part through the use of large-volume ventilation systems that remove methane from the mine and rel...

Catalytic Abatement of Methane Emission from CNG Vehicles: An Overview

Compressed natural gas (CNG) is a substitution of alternative fuel for automotive application with significant environmental advantages as it is the only fuel cheaper than gasoline or diesel, comparatively lower air pollution emissions, lesser CO2 emissions. However, emission of methane is 40% more in CNG fuelled engines compared to gasoline and diesel. With the exponential growth in CNG fuelle...
