“…Very early on, modifiers were added to avoid secondary reactions of cracking and isomerization leading to the formation of coke [10]. It has also been established that the presence of hydrogen in the gas phase prevents the deactivation of Pd nanoparticles by suppressing coke formation, in contrast to what has been observed in the absence of hydrogen [52][53][54]. In a study of toluene hydrogenation on Pt/Al 2 O 3 , Taimoor and Pitault [55] observed a slow and reversible deactivation even in the presence of hydrogen and demonstrated that this was due to a strong adsorption of toluene on alumina.…”

The term LOHC stands for Liquid Organic Hydrogen Carriers. The term has been so well accepted by the scientific community that the studies published before the existence of this name are not very visible. In this mini-review, we have tried to rehabilitate various studies that deserve to be put back in the spotlight in the present context. Studies indeed began in the early 1980s and many publications have compared the use of various organic carriers, various catalysts and reactors. Recent reviews also include the economic aspects of this concept.

“…In addition to the aforementioned CMR types, researchers also explored alternative modules and operating conditions. Kreuder et al [98] prepared various catalysts with Pt and Pt-Sn as the active material and Al 2 O 3 prepared by different ways and also CeO 2 -ZrO 2 as the support materials, with catalysts coated on the wall of thin foils inside a microstructured reactor, and compared their performances. They found that 1 wt% Pt/Al 2 O 3 showed the best performance but reported fast deactivation of catalysts by carbon formation on the catalyst surface at normal pressure (~1 bar).…”

Methylcyclohexane (MCH), one of the liquid organic hydrogen carriers (LOHCs), offers a convenient way to store, transport, and supply hydrogen. Some features of MCH such as its liquid state at ambient temperature and pressure, large hydrogen storage capacity, its well-known catalytic endothermic dehydrogenation reaction and ease at which its dehydrogenated counterpart (toluene) can be hydrogenated back to MCH and make it one of the serious contenders for the development of hydrogen storage and transportation system of the future. In addition to advances on catalysts for MCH dehydrogenation and inorganic membrane for selective and efficient separation of hydrogen, there are increasing research interests on catalytic membrane reactors (CMR) that combine a catalyst and hydrogen separation membrane together in a compact system for improved efficiency because of the shift of the equilibrium dehydrogenation reaction forwarded by the continuous removal of hydrogen from the reaction mixture. Development of efficient CMRs can serve as an important step toward commercially viable hydrogen production systems. The recently demonstrated commercial MCH-TOL based hydrogen storage plant, international transportation network and compact hydrogen producing plants by Chiyoda and some other companies serves as initial successful steps toward the development of full-fledged operation of manufacturing, transportation and storage of zero carbon emission hydrogen in the future. There have been initiatives by industries in the development of compact on-board dehydrogenation plants to fuel hydrogen-powered locomotives. This review mainly focuses on recent advances in different technical aspects of catalytic dehydrogenation of MCH and some significant achievements in the commercial development of MCH-TOL based hydrogen storage, transportation and supply systems, along with the challenges and future prospects.

“…Pd-based membrane reactors have already been developed for the dehydrogenation of LOHC methylcyclohexane, and the steam reforming of methane, where promising results could be achieved [3,8,9,72,73,74,75]. For adaptation to the multiphase system 18H-DBT/0H-DBT/H 2 , a multi-stage reactor concept with intermediate separation of hydrogen was developed.…”

Hydrogen production and storage in small and medium scale, and chemical heat storage from renewable energy, are of great interest nowadays. Micro-membrane reactors for reforming of methane, as well as for the dehydrogenation of liquid organic hydrogen carriers (LOHCs), have been developed. The systems consist of stacked plates with integrated palladium (Pd) membranes. As an alternative to rolled and electroless plated (Pd) membranes, the development of a cost-effective method for the fabrication of Pd membranes by suspension plasma spraying is presented.
