abstract = {Energy storage via liquid organic hydrogen carrier (LOHC)
systems has gained significant attention in recent times. A
dibenzyltoluene (DBT) based LOHC offers excellent properties
which largely solve today's hydrogen storage challenges.
Understanding the course of the dehydrogenation reaction is
important for catalyst and process optimization. Therefore,
reliable and exact methods to determine the degree of
hydrogenation (doh) are important. We here present other
possible techniques, namely: comprehensive two-dimensional
gas chromatography coupled with time of flight mass
spectrometry (2D-GC-TOF-MS) and single quadrupole-mass
spectrometry gas chromatogram system (GC-SQ-MS). The
2D-GC-TOF-MS results indicate that isomer fractions lose
three molecules of hydrogen, as follows: H18-DBT, H12-DBT,
H6-DBT and H0-DBT, and the doh decreases with an increase in
dehydrogenation temperature. 1H NMR and GC-SQ-MS were
employed as additional analytical techniques. The GC-SQ-MS
was also used to analyse decomposition products that result
from thermal cracking of reaction mixture molecules.},
