A comprehensive review of hydrogen production from methanol thermochemical conversion for sustainability

Gabriel Garcia et al.

Summary: This review discusses various methods of hydrogen production from methanol, with a focus on catalyst development and reactor technology. Copper-based catalysts are popular due to their high activity and selectivity but have stability issues, leading to exploration of other metals like zinc and chromium. Novel reactor structures such as porous copper fiber sintered-felt and membrane reactors have been explored for improved efficiency and energy savings.

Hydrogen production by ammonia decomposition over ruthenium supported on SiC catalyst

M. Pinzon et al.

Summary: The study investigates the impact of catalyst preparation conditions on hydrogen production from ammonia decomposition. It is found that Ru dispersion and metallic particle size significantly affect catalytic activity. Calcination in a nitrogen atmosphere enhances catalytic activity, and lower reduction temperatures lead to more active ruthenium particles. Maximum intrinsic activity is achieved with Ru particle size around 5 nm under specific conditions.

Kinetic assessment of H2 production from NH3 decomposition over CoCeAlO catalyst in a microreactor: Experiments and CFD modelling

Hesam Maleki et al.

Summary: A flat-plate microreactor was designed for on-board hydrogen generation through ammonia decomposition using CoCeAlO catalyst, with catalyst synthesis and immobilization assisted by inkjet printing technology. Kinetic experiments were conducted to analyze the impact of reaction temperature and NH3 flow rate, resulting in the development of two kinetic rate expressions and successful implementation in a CFD model. The simulation demonstrated high accuracy in predicting flow properties, with the microreactor operating under kinetic-control conditions and offering ease of component assembly and catalyst probing.

Ru-Based Catalysts for Ammonia Decomposition: A Mini-Review

Chongqi Chen et al.

Summary: Ammonia with a hydrogen content of 17.6 wt % is considered a promising hydrogen carrier with established infrastructures for production, storage, and transportation. Various metal-based catalysts, especially Ru-based ones, have been developed for NH3 decomposition, aiming to improve performance by reducing Ru loading and reaction temperature. Research focuses on support materials such as carbon (CNTs, CNFs, graphene) and metal oxides (Al2O3, MgO, SiO2) to understand the relationship between catalytic performance and structure.

Development of a Ba-CoCe catalyst for the efficient and stable decomposition of ammonia

Natalia Morlanes et al.

Summary: Barium-promoted cobalt-cerium catalysts prepared by coprecipitation exhibit high efficiency and stability in decomposing ammonia, showing similar activity and better stability compared to benchmark solids containing Ru. Cerium plays a key role in promoting the structure, leading to increased cobalt dispersion and prevention of sintering. The promotion of barium decreases the apparent activation energy and the negative hydrogen reaction order, improving the catalytic activity by alleviating the negative effect of hydrogen and reducing the hydrogenation properties of cobalt.
