Macrokinetic effects in perhydro-N-ethylcarbazole dehydrogenation and H₂productivity optimization by using egg-shell catalysts

Abstract

This contribution deals with pore diffusion influences on the dehydrogenation kinetics of perhydro-N-ethylcarbazole (H12-NEC).

Palladium Supported on Carbon Nanotubes as a High-Performance Catalyst for the Dehydrogenation of Dodecahydro-N-ethylcarbazole

“…Although there are many studies about the dehydrogenation reaction from calculations and experiments [20][21][22][23][24][25][26][27][28], the dehydrogenation reaction is still the key to limit its large-scale application, especially, the development of dehydrogenation catalysts with outstanding activity and stability is the hotspot of current research. A large number of dehydrogenation catalysts have been extensively investigated, including homogeneous catalysts and the heterogeneous catalysts [29][30][31][32][33][34][35]. For the homogeneous catalysts, Wang et al firstly reported the synthesis of homogeneous Ir-complex catalysts and explored its performance for the hydrogen release of dodecahydro-N-ethylcarbazole at 473 K but the dehydrogenation results were unsatisfactory [34].…”

“…Herein, in this work, for the first time, we have utilized an alcohol reduction method to construct CNT-supported Pd NPs (Pd/CNTs) as the catalyst for hydrogen generation from dodecahydro-N- A large number of dehydrogenation catalysts have been extensively investigated, including homogeneous catalysts and the heterogeneous catalysts [29][30][31][32][33][34][35].

“…Furthermore, Kustov et al [37] confirmed that the catalytic activity of the catalysts can be improved under microwave activation. Although Pd based catalysts supported several supports, such as alumina, silica, TiO 2 , MoO 3 and carbon [29][30][31][32][33][35][36][37][38], have been systematically investigated for producing hydrogen from perhydro-N-ethylcarbazole, there are no reports about CNTs as the supporting material in the hydrogen release from perhydro-N-ethylcarbazole.…”

Local extinction and reignition mechanism in a turbulent lifted flame: A direct numerical simulation study

“…[12]. In the flamelet scenario, the diffusion tangential to the mixture-fraction iso-surface is negligible and heat is diffused away from the surface in the normal direction [25]. The propagation of an edge-flame towards the unburned region will result in the heat being diffused away from the surface in the normal direction and diffused towards closing the hole in the plane of mixture-fraction iso-surface,…”

Insight into the adsorption of a liquid organic hydrogen carrier, perhydro-i-dibenzyltoluene (i = m, o, p), on Pt, Pd and PtPd planar surfaces

“…[2][3][4][5][6][7][8][9][10] Cost: the initial cost of setting up RES is high. [11][12][13][14][15] Storage: the most commonly used energy storage medium is batteries; however, with the increasing demand, especially for electric vehicles, mineral sources (such those of Li, which plays an integral role in batteries) are continually being depleted, hence leading to increasing production costs. 1,11,12,[15][16][17] Transportation: transportation is closely associated with issues of storage; safe transportation requires safe energy storage technologies.…”
