“…Viable commercial application requires more efficient hydrogen utilization. Coupling 2-butanol dehydrogenation with furfural hydrogenation generates two high value products (2-butanone and furfuryl alcohol) that can be readily separated (100 K difference in boiling points at 1 atm) by standard distillation [32]. Au/CeO 2 exhibited negligible activity in the dehydrogenation of 2-butanol and there is a requirement for an alternative (dehydrogenation) catalytic metal.…”

Application of nano-scale supported Au in catalytic hydrogenation delivers high chemoselectivity but low activity using (pressurized) H 2 far in excess of stoichiometric requirements. We have tackled the issues of low reaction rate and inefficient hydrogen utilization through a series of approaches taking Au/CeO 2 (mean Au size = 2.8 nm) as a test catalyst. Increased spillover hydrogen (using physical mixtures of Au/CeO 2 with CeO 2 and SiO 2 ) and the promotional effect of water (via catalytic dissociation on surface oxygen vacancies) resulted in a fourfold increase in the selective rate of furfural hydrogenation to furfuryl alcohol. In contrast, Pd/CeO 2 and Ni/CeO 2 promoted decarbonylation (to furan), hydrogenolysis (to 2-methylfuran) and ring reduction (to tetrahydrofurfuryl alcohol). Coupling (2-butanol ? 2-butanone) dehydrogenation over Cu/SiO 2 (mean Cu size = 7.8 nm) with furfural hydrogenation over Au/CeO 2 further increased rate with full utilization of the hydrogen generated in dehydrogenation. The coupling strategy allows ''hydrogen free'' hydrogenation that circumvents the limitation of Au in standard catalytic hydrogenation. This can open new avenues to exploit the ultra-selectivity of Au for continuous production of high value commodity products.

“…[449]. In addition, BDO can store up to 4.4 wt.%H 2 and 45 gH 2 /L and presents an attractive dehydrogenation enthalpy [397,[450][451][452]. Due to its high boiling point (230 °C), BDO dehydrogenation was studied in both liquidand gas phases with most literature focusing on the gas phase.…”

Greenhouse gas anthropogenic emissions have triggered global warming with increasingly alarming consequences, motivating the development of carbon-free energy systems. Hydrogen is proposed as an environmentally benign energy vector to implement this strategy, but safe and efficient large-scale hydrogen storage technologies are still lacking to develop a competitive Hydrogen economy. LOHC (Liquid Organic Hydrogen Carrier) improves the storage and handling of hydrogen by covalently binding it to a liquid organic framework through catalytic exothermic hydrogenation and endothermic dehydrogenation reactions. LOHCs are oil-like materials that are compatible with the current oil and gas infrastructures. Nevertheless, their high dehydrogenation enthalpy, platinoid-based catalysts, and thermal stability are bottlenecks to the emergence of this technology. In this review, hydrogen storage technologies and in particular LOHC are presented. Moreover, potential reactivities to design innovative LOHC are discussed.

“…The interaction between the adiabatic reactor and the separation section, due to material recycle, may be the source of undesired nonlinear phenomena (such as instability and parametric sensitivity, which leads to controllability problems. Behavior of integrated systems is analyzed in few studies and found this new process intensification technique feasible and beneficial. This article presents the design of an integrated plant for the combined production of TOL and AN.…”

The scope of this study is to emphasize the possibility and benefits of direct coupling of exothermic and endothermic reactions. Simultaneous production of aniline by exothermic nitrobenzene hydrogenation and endothermic dehydrogenation of methyl-cyclohexane to toluene is investigated. Instead of multitubular reactor, the reaction is carried out in an adiabatic reactor eliminating the requirement of complex setup of the hydrogenation reactor. Additionally, large amount of hydrogen needed to avoid reaction runaway is no longer needed. Nonlinear analysis of reactor-separation-recycle shows difficulty in controlling integrated plants where unreacted reactant is recycled.Details of the plant design, obtained by Aspen Plus simulation, are given. The new integrated system is feasible with the benefits of simple reactor and reduce hydrogen requirement. Economic analysis shows that the total annual cost of coupled system is reduced by 20%. The results obtained here are also applicable to other chemical processes of practical relevance.
