Effect of isomerization on the performance of aromatic hydrogen storage systems possessing different condensation extents

The influence of structural differences in cis- and trans-conformer molecules of ortho-, meta- and para-isomers of perhydroterphenyl and decalin on the hydrogen release in hydrogen storage systems was estimated for the Pt/C catalyst in a flow regime. The structural differences between the cis- and trans-conformers of perhydroterphenyl did not significantly affect the reactivity of its ortho-, meta- and para-isomers. In the case of decalin, the decrease in the volume of released hydrogen due to the conversion of its cis-isomer into the less active trans-form was clearly demonstrated.
