Improvements on thermal efficiency of chemical heat pump involving the reaction couple of 2-propanol dehydrogenation and acetone hydrogenation

Hydrogen storage by decalin dehydrogenation/naphthalene hydrogenation pair over platinum catalysts supported on activated carbon

“…(1)) has been successfully applied to describe the catalytic dehydrogenation of 2-propanol [27] and decalin [28]:…”

Dehydrogenation of N-ethyl perhydrocarbazole catalyzed by PCP pincer iridium complexes: Evaluation of a homogenous hydrogen storage system

“…The utilization of liquid aromatic organic compounds as hydrogen carriers has remained a tantalizing but impractical possibility for over 60 years [2][3][4][5][6][7][8][9][10][11][12][13][14]. A liquid hydrogen storage media could be economically manufactured in the massive quantities to meet the anticipated demand and eliminate many of the problems commonly associated with systems based on hydrogen absorbing solids including: thermal management on charging and other issues relating to the compatibility with existing infrastructure.…”

“…In many ways such an onboard energy carrier can be thought of as ''recyclable gasoline". Initial efforts to develop liquid organic hydrogen carriers were primarily focused on cycloalkanes [2][3][4][5][6]. The dehydrogenation of these cheap and abundant materials to the corresponding aromatic compounds releases approximately 7 wt% hydrogen.…”

Advances in Organic Liquid‐Gas Chemical Heat Pumps

“…Subsequently, Doi et al [42] further studied the dehydrogenation reaction of isopropanol when using carbon-supported Ru-Pd as a catalyst. By conducting the dehydrogenation reaction of 2-propanol with Ru or Ru-Pt catalyst, Meng et al [43] found that the thermal efficiency of an isopropanol-acetone-hydrogen CHP could be greatly improved. A high value was attained for both the fraction of heat used for the endothermic reaction (25.6 %) and the exergy efficiency (58.6 %).…”
