In-situ neutron imaging of hydrogenous fuels in combustion generated porous carbons under dynamic and steady state pressure conditions

Abstract
We report results from experiments where we characterize the surface properties of soot particles
interacting with high-pressure methane. We find considerable differences in behavior of the soot material
between static and dynamic pressure conditions that can be explained by multiscale correlations in
the dynamics, from the micro to macro of the porous fractal-like carbon matrix. The measurements were
possible utilizing cold neutron imaging of methane mixed with combustion generated carbon (soot)
inside steel cells. The studies were performed under static and dynamic pressure conditions in the range
10e90 bar, and are of interest for applications of energy storage of hydrogenous fuels. The very high... (More)

sections for neutrons compared to hard X-ray photons, enabled us to find considerable amounts of native
hydrogen in the soot and to see and quantify the presence of hydrogen atoms in the carbon soot matrix
under different pressure conditions. This work lays the base for more detailed in-situ investigations on
the interaction of porous carbon materials with hydrogen in practical environments for hydrogen and
methane storage. (Less)
