The main challenge in using hydrogen as a clean energy source is the need for dependable storage technology.

Carbon nanotube-based materials stand out among material-based hydrogen storage systems due to their unique advantages over others. High surface area, mesoporous structure, tunable features, honeycomb structure, chemical stability, low mass density, hydrogen molecule dissociation and an easy synthesis process are only a few of its distinctive qualities. Many material-based hydrogen storage systems rely on chemisorption, lacking reversibility and necessitating energy for hydrogen release. In contrast, CNT-based materials predominantly employ physisorption, merely adsorbing hydrogen without chemical bonding. This approach allows for more efficient hydrogen release, ensuring superior stability and reversibility compared to other material-based systems. This review paper assesses the hydrogen storage capabilities, different properties and rapid adsorption/desorption kinetics of carbon nanotube-based materials at lower temperatures.

Bio-jet fuel is expected to play a crucial role in achieving this target, and the demand for bio-jet fuel is projected to rapidly increase. Bio-oil from fast pyrolysis of lignin, such as waste wood, is considered a promising alternative for production of bio-jet fuel through processes such as hydrodeoxygenation. In this study, the physical properties and compositions of bio-jet fuel produced from wood-derived pyrolysis bio-oil blended with petroleum-based jet fuel as well as their changes during 16 weeks storage were investigated. Consistently, 0%, 10%, 50%, and 100% blended bio-jet fuels were prepared. After 16 weeks of aging, the total acid number of the all-blended bio-jet fuel showed a sharp increase from 12 weeks, reaching over 0.1 mg KOH/g. Additionally, kinematic viscosity showed a steady increase over 16 weeks whereas oxidative stability decreased by approximately 20% at 16 weeks for the 100% bio-jet fuel alone. The final boiling point increased by up to 20% in higher blends of bio-jet fuel and the average molecular weight increased. Bio-jet fuel has a high olefin content, which can further increase during storage, leading to a decrease in the combustion characteristics. This study suggests that using up to 10% the bio-jet fuel in aircraft is safe considering storage stability, but further research is required to confirm this finding.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"41 13","pages":"3631 - 3646"},"PeriodicalIF":2.9,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11814-024-00309-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this, the surface of the QDs was engineered by attaching ferrocyanide ligands. This surface modification enabled the QDs to be seamlessly and uniformly incorporated into the PBA matrix. The ferrocyanide ligands on the QD surfaces played a pivotal role in initiating the <i>in-situ</i> formation of PBA, facilitated by the introduction of additional ferrocyanide ions and iron (III) ions as the building blocks of PBA. Alternatively applied external voltages to the QD-in-PBA electrode within an electrochemical cell demonstrated the reversible quenching and recovery of the PL intensity of the QDs embedded within the QD-in-PBA composite.

In contrast, the control sample, comprising a mixture of QDs and PBA, exhibited poor stability in terms of electrochemical performance, with a reduced modulation degree observed over repeating cycles.

However, the yield of saturated hydrocarbons during hydroprocessing of refined UCO (r-UCO) can be lowered by the formation of oligomers via double bonds present in unsaturated TAG and via those produced by dehydration of hydroxy groups of MAG and DAG and β-elimination of (un)saturated TAG.

The other attempt was to prove very successful in both modes of experiments regardless of the presence of polar substances in r-UCO; thus, continuous-flow hydroprocessing of r-UCO could be sustained for 100 h without oligomer formation.
