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. \n\nThe 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 : \nSheridan Mayo, Matthew Josh, Dane Kasperczyk, James Kear, Junfang Zhang, Jeremie Dautriat, Marina Pervukhina, Michael Ben Clennell, Richard Sakurovs, Neil Sherwood, Anton Maksimenko, Chris Hall, Dynamic micro-CT study of gas uptake in coal using Xe, Kr and CO2, In Fuel, Volume 212, 2018, Pages 140-150, https://doi.org/10.1016/j.fuel.2017.10.041\nLineage: The data were collected over three days at the Imaging and Medical Beamline (IMBL) at the Australian Synchrotron. Raw data was reconstructed using the X-TRACT software on the MASSIVE supercomputer facility. 3D image alignment for the aligned datasets was done using Avizo software.

本数据集为2016年4月开展的一项同步辐射实验的系列数据集之一，该实验以煤炭中的气体扩散过程为观测对象。本数据集涵盖二氧化碳（CO₂）气体扩散相关实验数据。

实验采用显微计算机断层扫描（micro-CT）技术，对直径约7mm的不同煤样开展了为期3天（即本次同步辐射实验的总时长）的气体扩散过程观测。部分相同的煤样分别暴露于加压氙气、氪气或二氧化碳环境中。前两种气体在显微CT图像中清晰可见，因此可直观观测其随时间的扩散过程。针对二氧化碳实验组，不仅可观测到煤样的膨胀现象，通过精细化分析还能捕捉到与气体吸附相对应的X射线衰减小幅变化。更多细节详见随附的支撑文档及如下学术论文：

数据溯源：本数据集于澳大利亚同步辐射装置的成像与医学束线（Imaging and Medical Beamline, IMBL）采集，耗时三天完成。原始数据借助MASSIVE超级计算集群的X-TRACT软件完成重建；对齐后的三维数据集则通过Avizo软件完成图像配准。
