Summary: This study reports the successful control of the textural properties of commercial alumina ball for Ni-supported catalysts in practical steam-methane reforming processes. By treating the alumina support with aqueous HCl for varying periods, the pore diameters and pore volumes of the alumina supports are finely tuned. The resulting Ni-supported alumina catalysts exhibit enhanced catalytic activity, attributed to increased intraparticle diffusion of reactant molecules inside the catalyst.

Summary: Metal dispersion is crucial for designing efficient catalytic systems. This study investigates the impact of Nb dispersion on the conversion of fructose to HMF using highly porous silica glasses grafted with niobium oxide. The results demonstrate that the niobium oxide impregnated silica glasses show significantly higher HMF productivities compared to the mesoporous NbOPO4 reference material. Interestingly, the formation of humin is strongly correlated with HMF yield regardless of the catalyst used, while metal dispersion affects the acidity profile.

Summary: Reductive Catalytic Fractionation (RCF) produces lignin oil and high-quality cellulosic pulps, but the complexity of lignin oil makes it challenging to analyze. To investigate the mechanisms of lignin stabilization and structural features of carbohydrates, fractionation methods are required. This study examines solvent fractionation as a method to produce lignin oil fractions for characterization. The solvent fractionation allows for determining structural heterogeneity using high-resolution HSQC NMR spectroscopy. The study also investigates the role of the hydrogenation catalyst in stabilizing lignin fragments and defining the structural features of hemicellulose-derived carbohydrates in lignin oil obtained by the RCF process.

Summary: Single superphosphate (SSP) is produced through complex reactions by direct reaction between phosphate rock concentrates and sulfuric acid in Brazil. The presence of iron oxide in the phosphate concentrates poses a challenge in SSP production, as it may result in the formation of water-insoluble iron phosphates with lower agronomic efficiency. However, the study found that with optimized reaction conditions, SSP with high NAC solubility and conversion rates nearing 100% can be achieved even with phosphate concentrates containing up to 14.7% Fe(2)O(3). These findings demonstrate the technical feasibility of using phosphate rocks with higher iron concentrations in industrial operations.

Summary: This study investigates the catalytic microwave-assisted pyrolysis of microalgae in a tandem catalytic bed, aiming to reduce the formation of unwanted compounds and enhance aromatic hydrocarbon production. The results show that the hydrotalcite catalyst promotes de-acidification and de-nitrification reactions, while the zeolite catalyst converts intermediate compounds into hydrocarbons. The maximum hydrocarbon and benzene yields are achieved at a temperature of 500 degrees C and a NiHTC/SiC:NiHZSM-5/SiC catalyst ratio of 1:1. The study also provides important data on energy recovery and bio-oil quality during the catalytic pyrolysis of microalgae.

Summary: The valorisation of lignin is crucial for the economic viability of the lignocellulosic biorefining industry. The lignin-first biorefining approach, which considers lignin valorisation in the design phase, has been shown to make the fullest use of lignocellulose. Despite the diverse approaches to reporting and analyzing results from lignin-first methods, we propose guidelines for analyzing critical data in order to facilitate direct comparisons between studies.
