Catalytic Activity of Oxidation Pretreated Hastelloy for Methanol Steam Reforming

Chemical Engineering Transactions, 2017
Hastelloy, a Ni containing alloy, was investigated to improve its catalytic activity on bio-oil steam reforming by oxidation pretreatment. Methanol as the major composition of bio-oil was used as a model compound.

Hydrogen production by the photo-reforming of methanol and the photocatalytic water gas shift reaction [PDF]

, 2021
We have examined the reforming of methanol and CO on Pd/P25 TiO2 catalysts for hydrogen production, and compared it with rates for similarly supported Au and Cu catalysts.

Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Modeling and optimization of methanol-fueled MIDREX reformers for energy-efficient hydrogen production

Energy Conversion and Management: X
This study evaluates, at the reformer level only, whether methanol can replace methane as the feed to a MIDREX reformer while still delivering MIDREX-compatible syngas.

Thermally Regulated Methanol Selectivity in Photo‐Thermo Methane Oxidation Through Interfacial Methyl Transfer

Advanced Science, EarlyView.
Photo‐thermo cascade catalysis enables highly selective methane‐to‐methanol conversion over Au‐ZnO, achieving a CH3OH production rate of ∼800 µmol h−1 with 86% selectivity. Thermal activation gates the transfer of methane‐derived methyl intermediates from ZnO to Au, thereby redirecting the reaction pathway toward methanol formation. ABSTRACT The direct
