Summary: In this study, ZSM-5 zeolite nanocrystals were successfully fabricated to improve the adsorptive desulfurization performance of traditional ZSM-5 zeolite. The nanocrystals effectively reduced the diffusion pathway, increased the specific surface area, and enhanced the desulfurization efficiency. Furthermore, ion exchange enhanced the meso-porous characteristics and Lewis acid sites, promoting the adsorption desulfurization performance.

Summary: This study investigates the physical properties and combustion behavior of blends of military jet fuel JP-5 with biodiesels synthesized from 13 plant oils, bacon grease, and duck fat. The biodiesels were found to have higher densities and viscosities than the maximum allowable limits for military diesel fuel, but their flash points and cetane numbers mostly met the requirements. Combustion experiments showed that blending 20% biodiesel with JP-5 had minimal impact on the combustion characteristics in a diesel engine.

Summary: This study evaluates the potential of a commercial molecular sieve for removing sulfur compounds from highly aromatic condensate on an industrial scale. The adsorbent is characterized using various techniques, and dynamic breakthrough experiments show that it effectively removes sulfur compounds from condensate with approximately 900 ppmw S, reducing the sulfur concentration to about 12 ppmw S. The study also focuses on finding a desorption method to prevent a sulfur concentration peak in tail gas.

Summary: The aviation sector contributes about 2% of global anthropogenic CO2 emissions, and efforts are being made to find cost-effective and environmentally-friendly bio-jet fuels derived from natural resources. Cultivation conditions for microalgae play a significant role in their growth rate and chemical composition, impacting the yield and quality of microalgae bio-jet fuel. The development of hydroprocessing techniques for converting microalgae oil into bio-jet fuel, as well as innovative approaches like gasification with Fischer-Tropsch and sugar-to-jet, offer promising alternatives to traditional aviation fuel production methods.

Summary: This study investigates the effect of aluminum doping on highly Ni-rich layered Li[Ni0.90Co0.05Mn0.05]O-2 cathodes. The results show that aluminum is effective in enhancing the electrochemical performance of the cathode at concentrations higher than 1%, but becomes detrimental at 3% or greater concentrations. The cathode with 2% aluminum doping delivers the most optimal electrochemical performance.
