Summary
Methane emissions associated with coal extraction are an environmental and safety risk, but also a potential source of clean
energy and chemicals. The scope of the present work is to develop an integrated approach for upgrading this methane in
ventilation emissions of working shafts (VAM) as well as those emissions coming from abandoned mines (AMM). This
strategy includes the evaluation of concentrations and flow rates in terms of the shaft geological and operational features
(working or flooded) and the design of separation processes and chemical reactors, either for methane combustion or for
transforming this methane in useful chemicals, such as hydrogen or methanol.
Different strategies are proposed: optimization of the mine operation for providing valuable flow rates and methane
concentrations, the development of methane concentration procedures (adsorption, membranes; using nanomaterials with
tailored properties); use of advanced reactors and combustion devices (thermal/catalytic reverse flow reactors, membrane
reactors, etc.) able to deal with these low concentrations. The final goal of the project is to propose integrated approaches
from the optimization of VAM and AMM extraction procedures to the fully upgrading of the methane contained in these
streams. For this purpose, the project includes in-situ geological studies, experimentation at lab scale, and computer-aided
simulation and optimization processes.
