Techno-economic assessment of hydrogen production via dimethylether steam reforming and methanol steam reforming

Indian Chemical Engineer, 2023
The present work reports the techno-economic analysis of hydrogen generation using Dimethyl Ether Steam Reforming (DMESR) and Methanol Steam Reforming (MSR) processes. For both processes, steady-state simulation models were developed using Aspen Plus.

Methanol steam reforming over Cu/SiC catalysts.

Journal of Advanced Science, 2001
Methanol steam reforming reaction over copper on silicon carbide (Cu/SiC) catalyst was investigated in the production of hydrogen for fuel cell applications. Catalytic performances (activities, hydrogen production amount and concentration of carbon monoxide (CO)) were highly dependent upon the calcmation temperature of the catalyst.

Steam reforming on transition-metal carbides from density-functional theory [PDF]

, 2009
A screening study of the steam reforming reaction (CH_4 + H_2O -> CO + 3H_2) on early transition-metal carbides (TMC's) is performed by means of density-functional theory calculations. The set of considered surfaces includes the alpha-Mo_2C(100) surfaces,

Simulation Study of a Membrane Reactor for Ultrapure Hydrogen Recovery from Methanol Steam Reforming Reaction under Periodic Steady-State

Bulletin of Chemical Reaction Engineering & Catalysis, 2018
Steam reforming of methanol over Cu/ZnO/Al2O3 catalyst was theoretically studied under created unsteady state. A mathematical approach was proposed to evaluate the effect of periodic inputs on reactor performance.

Intensification of methanol steam reforming process using Cu-modified Ni-based supported catalysts [PDF]

, 2019
Hydrogen is conventionally manufactured in large scale by the steam reforming of methane or naphthas. The perspective of using hydrogen as a fuel depends of finding alternatives to the existing production technologies and feedstock. Oxygenated compounds

Pulsed Electrolysis Prevents Sulfur Poisoning for Sustained Sulfide Valorization

Advanced Materials, EarlyView.
Integrating pulsed electrolysis with Sc‐doped NiFe‐LDH enables sustainable sulfide valorization, achieving >500 h stability, 99.8% efficiency. Moreover, this technology produces high‐purity sulfur and sodium formate, boosting profit by 121% to $1,294.7 per tonne of hydrogen.
