Synchrotron micro-CT scans of the gas diffusion process in coal (CO2 aligned data)

This collection is one of a set from a synchrotron experiment performed in April 2016 observing gas diffusion process in coal . This collection contains the data for CO2 gas diffusion.

The gas diffusion process in different coals samples of around 7mm diameter was observed using micro-CT over a period of 3 days (the duration of the synchrotron experiment). Similar samples were exposed to pressurised xenon, krypton or CO2. The first two gases are clearly visible in the micro-CT images so diffusion over time can be easily observed. For the CO2 the swelling can be observed and with detailed analysis a small change of x-ray attenuation corresponding to gas uptake can also be observed. More details are given in the documents included as a supporting attachment.and in the paper :
