Hydrogen evolution in the dehydrogenation of methylcyclohexane over Pt/Ce Mg Al O catalysts derived from their layered double hydroxides

Recent Trends on the Dehydrogenation Catalysis of Liquid Organic Hydrogen Carrier (LOHC): A Review

“…As for the catalyst support, the most basic support is Al 2 O 3 [13,14,[17][18][19][20], and as other options, Mg-Al-O [15,21], USY zeolite [22], TiO 2 [17,23], TiO 2 -Al 2 O 3 [17,20], and Silicalite-1 [16] are reported. In addition to the role of high dispersion of Pt particles, the support material is also expected to suppress the aggregation of Pt particles by strong metal-support interaction (SMSI) (anchoring effect) and electron transfer between Pt and support.…”

“…In addition to the role of high dispersion of Pt particles, the support material is also expected to suppress the aggregation of Pt particles by strong metal-support interaction (SMSI) (anchoring effect) and electron transfer between Pt and support. Wang et al reported that Pt/Ce-Mg-Al-O, which is Mg-Al-O combined with a small amount of Ce, shows high MCH dehydrogenation activity with a conversion rate of 98.5% [21]. The addition of CeO 2 to the support has been found to improve the dispersion of Pt particles.…”

Simulation Study to Investigate the Effects of Operational Conditions on Methylcyclohexane Dehydrogenation for Hydrogen Production

“…Chen et al designed and optimized the catalytic membrane reactor for MCH dehydrogenation to produce hydrogen [23]. Wang et al, carried out MCH dehydrogenation using Pt/Ce-Mg-Al-O catalyst, and achieved a MCH conversion rate of 98.5% [24]. Obara carried out energy and exergy analysis of a complete hydrogen energy supply chain using MCH and reported the total efficiency to be 18% with a heat to power ratio of 0.931 [25].…”

Dielectric barrier discharge plasma grafting carboxylate groups on Pt/Al2O3 catalysts for highly efficient hydrogen release from perhydro-dibenzyltoluene

“…[8][9][10][11] Compared to other LOHC materials such as N-ethylcarbazole (NEC) and methylcyclohexane, dibenzyltoluene (DBT) is a potential candidate with low vapor pressure, noncarcinogenicity, low ignitability, good thermal stability, and a high hydrogen storage capacity of 6.2 wt%. 3,[12][13][14][15][16][17][18] In addition, the low melting point (−35 °C) and high boiling point (390 °C) of DBT provide an interesting option for storage and transportation of hydrogen in the liquid state, thus making it accessible to the existing oil infrastructure. [19][20][21] DBT is a commercially available heat transfer oil with low cost.…”
