Parametric study of the hydrogenation of dibenzyltoluene and its dehydrogenation performance as a liquid organic hydrogen carrier

Hydrogenation of dibenzyltoluene and the catalytic performance of Pt/ Al 2 O 3 with various Pt loadings for hydrogen production from perhydro‐dibenzyltoluene

“…It was found from the wide scan XPS spectra that the overlap between Pt4f lines and Al2p lines made the analysis of Pt/Al 2 O 3 complicated. 45,46 Figure 3 depicts the high-resolution XPS spectra of Pt 4f and Al 2p regions. After the Pt4f curve fitting, the spectrum features two components at binding energies of 71.2 eV (Pt 4f 7/2 ) and 74.5 eV (Pt 4f 5/2 ) assigned to metallic Pt.…”

“…The schematic of this setup is shown in Figure 5 and the complete description of this experimental setup is provided in the previous work. 45,46 The reactor was provided with two K-type thermocouples to monitor the temperature of the material inside the reactor and the heater. The pressure transducer was installed to examine the pressure variations inside the reactor during the experiment.…”

“…The selection of the Raney-Ni catalyst was based on the previous hydrogenation of the H0-DBT study by the authors. 45,46 It is proven as an efficient catalyst that is why we opted for this catalyst for the current study. All the experiments were conducted at an initial pressure of 5 MPa and a stirring speed of 800 rpm.…”

Novel Catalysts for Dibenzyltoluene as a Potential Liquid Organic Hydrogen Carrier Use—A Mini-review

“…The results indicated that Pd and bimetallic Pt–Pd catalyst activity is lower compared to that of pure Pt during H18-DBT dehydrogenation and the activation energy values were for 1 wt % Pt/Al 2 O 3 205 kJ/mol, 1 wt % Pd/Al 2 O 3 84 kJ/mol, and 1:1 wt % Pt–Pd/Al 2 O 3 66 kJ/mol. Ali et al studied a Pt–C catalyst for the dehydrogenation process . The performance of the dehydrogenation of perhydro-DBT was studied at 290 °C and yielded 97.70% of the stocked hydrogen.…”

Performance Analysis of the Perhydro-Dibenzyl-Toluene Dehydrogenation System—A Simulation Study

“…The authors reported that hydrogenation and dehydrogenation can be done in the same pressure swing reactor with this concept. Ali et al [32] performed dehydrogenation of PDBT (4.26 wt. % and 2 wt.…”
