Summary: The addition of iron, cobalt, or nickel to a prepared niobium-supported catalyst using mesoporous silica SBA-15 as a support significantly influenced the hydrodeoxygenation (HDO) reaction of anisole. Nickel incorporation showed the highest anisole conversion and selectivity to deoxygenated products, followed by cobalt and iron. The superior performance of NiNb/SBA-15 was associated with its lower acidity, higher Nb/Si surface exposure, NbO2/Nb2O5 ratio, and better interaction between nickel and niobium species.

Summary: The combination of first-row transition compounds or nanoparticles with silica-based supports provides a promising approach for catalyst design. Iron, cobalt, and nickel-based materials are particularly attractive due to their availability, low cost, and unique reactivity, which allows for transformations not achievable with noble metals. Mesoporous silica-based supports, with their high surface area, tunable pore size and volume, as well as thermal and chemical stability, are of great interest for catalyst adsorption and reactant diffusion. However, despite their wide application, it remains challenging to predict or understand the key features of silica-supported first-row transition metals-based catalysts. A review on the rational tailoring and application of nano-sized materials immobilized on silica-based supports in catalysis is necessary.

Summary: This study investigated the effect of different metal promoters on the catalytic activity of Ni catalysts for the reforming of plastic pyrolysis gas. It was found that using gasification slag from municipal solid waste as a support material showed stable conversion efficiency and good thermal stability. The Ni-Mo catalyst demonstrated the highest conversion efficiency, H2 and CO yields, and lowest coke deposition, and also showed the growth of carbon nanotubes. These findings suggest that Ni catalyst promoted by Mo and loaded on a gasification support has high potential for syngas production from plastic pyrolysis gas.

Summary: The study investigated the catalytic activity and stability of nickel, platinum, rhodium, and ruthenium-based catalysts during hydrogen production from steam reforming of liquefied petroleum gas. It was found that rhodium and platinum catalysts exhibited higher catalytic activity and lower deactivation compared to nickel and ruthenium catalysts. Small increases in particle sizes of Ni(0) and Ru(0) during the process could contribute to the faster deactivation of Ru/CS and Ni/CS catalysts.

Summary: In this study, the role of anions in biomass pyrolysis catalyzed by nickel salts was investigated by impregnating four types of nickel salts (Ni(NO3)2, NiSO4, (CH3COO)2Ni, NiCl2) on reed. The results showed that nickel salts inhibited the release of volatiles from biomass and increased the yield of bio-char, with NiCl2 being the most effective. NiSO4 significantly increased the specific surface area and graphitization of bio-char, and improved the selectivity of phenolic compounds in bio-oil (62.27%) and the concentration of CO in pyrolysis gas (37.78%). The addition of NiCl2 enhanced the selectivity of ketone-rich oil (26.95%) and hydrogen-rich gas (56.39%). Ni(NO3)2 was weaker than other nickel salts in catalyzing the cleavage of macromolecular compounds. This research offers a prospective approach to control the distribution and quality of pyrolysis products by using suitable catalyst precursors.

The addition of catalysts significantly increased the oil yield and hydrocarbon content, while reducing the phenolic compounds content. Catalyst addition also promoted the formation of cyclic hydrocarbon relative to aliphatic hydrocarbon.

Summary: Catalytic pyrolysis of pine sawdust was utilized to produce valuable alkylphenol compounds by introducing surface active groups, such as metal iron species and oxygen-containing groups, to strengthen the biochar-based catalyst. The presence of these active sites promoted the conversion of pyrolytic intermediates into phenolic compounds during catalytic pyrolysis. The deactivated catalyst could be easily regenerated and showed a good selectivity for phenol production.

Summary: This study proposes a carbon-negative process for producing high purity hydrogen from organic waste, and evaluates its feasibility in Sweden. The process combines anaerobic digestion, pyrolysis, catalytic reforming, water-gas shift, and pressure swing adsorption technologies. Under optimal operating conditions, the process can produce 72.2 kg H2 and 701.47 kg negative CO2 equivalent emissions from 1 ton of dry organic waste. The techno-economic assessment shows that implementing the process in Stockholm can achieve an internal rate of return of 26% and a discounted payback period of 4.3 years when negative CO2 equivalent emissions are recognized as income.
