Hydrogen storage by liquid organic hydrogen carriers: Catalyst, renewable carrier, and technology – A review

Carbon Resources Conversion, Journal Year: 2023, Volume and Issue: 6(4), P. 334 - 351

Published: March 21, 2023

Hydrogen has attracted widespread attention as a carbon-neutral energy source, but developing efficient and safe hydrogen storage technologies remains huge challenge. Recently, liquid organic carriers (LOHCs) technology shown great potential for stable transport. This allows economical large-scale transoceanic transportation long-cycle storage. In particular, traditional liquids are derived from nonrenewable fossil fuels through costly refining procedures, resulting in unavoidable environmental contamination. Biomass holds promise the preparation of LOHCs due to its unique carbon-balance properties feasibility manufacture aromatic nitrogen-doped compounds. According recent studies, almost 100% conversion 92% yield benzene could be obtained advanced biomass technologies, showing preparing biomass-based LOHCs. Overall, present systems their applications introduced this review, technical paths summarized. Furthermore, paper provides an outlook on future development technology, focusing biomass-derived N-doped compounds

Insights into the thermal stability and conversion of carbon-based materials by using ReaxFF reactive force field: Recent advances and future directions

Carbon, Journal Year: 2022, Volume and Issue: 196, P. 840 - 866

Published: May 26, 2022

Molecular simulations based on reactive force-fields (ReaxFF) have been applied as a powerful tool for exploring the dynamics evolution of complex carbonaceous materials. A comprehensive review thermal degradation reactions renewable and nonrenewable carbon precursors at different conditions is presented, aiming gaining molecular insights mitigating heavy deposition in undesirable scenarios using simulation tools, while providing some perspectives future directions subject. The divided three main interconnected areas: (i) overview implementation ReaxFF simulations, structural extraction techniques microstructural characteristic properties carbon-based materials, followed by (ii) proposed biomass, bio-oil, bio-fuel reaction mechanisms from which, tendency coke char formation tackled. Finally, (iii) understanding coal, soot, coal char, petroleum derivatives (petcoke) materials reactivity under high-temperature thermochemical reactions. critical discussion presented effects temperature functional groups large-scale atomistic structures, initial ring cleavage reactions, along with generated products yields characteristics. Suggested improvements methodology parametrization approach are made, incorporating catalytic surfaces tackling bio-oil upgrading regards to deposition.

The non-isothermal kinetics and pyrolysis characteristics of biomass waste including camphor wood (CW), pure glycerol (PG) a blend (1:1 mass ratio) (PG-CW) were studied by coupling TG-MS/DSC techniques. samples heated from ambient temperature to 700 °C at different heating rates (10, 15, 20 25 °C/min) in nitrogen atmosphere. loss during the evolution gas products studied. improved Coats-Redfern method was used obtain kinetic parameters for pyrolysis, activation energies pre-exponential factors estimated iteratively regression improve their accuracy. PG had only one main phase, while CW two phases. results showed that adding into reduced residue increased amount released after co-pyrolysis. model based on iterative entirely fitted phases CW, PG, PG-CW. suitable models second, third, fourth nucleation, one-dimensional diffusion, respectively.
