Visualization of clathrate hydrate coexisting with water and ice in a nondestructive manner is very effective for evaluating its stability. However, conventional methods such as white X-ray CT and MRI cannot distinguish ice from clathrate hydrate. In this presentation, the results of our attempt to visualize various clathrate hydrates by using monochromatic absorption contrast X-ray CT method with low energy X-ray using synchrotron radiation will be presented.
