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

摘要

Ventilation air methane (VAM) found in coal mines is a huge and global problem because it acts as a greenhouse gas (GHG) contributing to climate change. Methods for removing this methane and reducing its impact have to date been limited due to a lack of legislative drivers and a technological focus on reducing the emissions of higher hydrocarbons. Now a new technology, known as COMETTM, has been developed at Johnson Matthey in collaboration with Anglo Coal for abating this methane emission source. This article describes the development of the catalytic system and its engineering aspects to the point where the technology is ready for commercial launch.
