Significance To meet the growing demand for sustainable aviation fuels (SAF), conversion pathways are needed that leverage wet waste carbon and jet fuel property specifications. Here, we demonstrate SAF production from food waste–derived volatile fatty acids (VFA) by targeting normal paraffins a near-term path to market branched isoparaffins increase renewable content long term. Combining these distinct paraffin structures was shown synergistically improve VFA-SAF flash point viscosity blend...
Already low volume (<1mL) test methods facilitate the development of sustainable aviation fuel platforms and higher fidelity computational methods. Here a novel technique with two-dimensional gas chromatography (GCxGC) Vacuum Ultraviolet (VUV) identification is used to characterize composition determine properties compared previous work.

Hydrothermal liquefaction (HTL) uses heat and pressure to liquefy the organic matter in biomass/waste feedstocks produce biocrude. When hydrotreated biocrude is converted into transportation fuels including sustainable aviation fuel (SAF). Further, by liquifying wet wastes such as sewage sludge, manure, food waste, HTL can prevent landfilling or other disposal methods anerobic digestion, incineration. A significant roadblock development of a new route for SAF strict approval process, large...
The steam reforming of coke oven gas (COG) for hydrogen production was investigated over the NiO/MgO solid solution catalysts reduced at high temperatures. It found that catalyst possessed good catalytic activity, and conversions CH4 CO2 were greatly affected by reaction temperature steam/carbon (S/C) mole ratio. During tested period 100 h under a low S/C ratio 1.0 875 °C, kept constant values around 97.6 44.3%, respectively, volume content enhanced from 58.2% in original COG to 77.7% 1.5...

A quantitative structure–property relationship model has been developed to predict the threshold sooting index (TSI) of arbitrary mixtures aliphatic and aromatic hydrocarbons known composition. The employs contributions from eight molecular fragments plus a global shift penalty factor for naphthenic compounds. For each coefficient, were determined by constrained regression data five different experimental campaigns, which stitched together setting TSI methylcyclohexane 5 1-methylnaphthalene...
A detailed assessment is presented on the calculation and uncertainty of lower heating value (net heat combustion) conventional sustainable aviation fuels, from hydrocarbon class concentration measurements, reference molecular heats formation, uncertainties these formation. Calculations using this paper's method estimations ASTM D3338 are reported for 17 fuels diverse compositions compared against D4809 measurements. All calculations made by measurements agree (i.e., within 95% confidence...
One of the challenges in developing 100% sustainable aviation fuels is effect synthetic blend components on dielectric constant. Modern aircraft often employ capacitance-based gauging systems that rely constant fuel onboard to determine quantity. Aircraft manufacturers have expressed concern over inaccuracies attributable variances between conventional jet and paraffinic fuel. In our study, density data were gathered from 172 samples establish a baseline "experience range." Subsequently,...
Economical production of lignin-based jet fuel (LJF) can improve the sustainability sustainable aviation fuels (SAFs) as well reduce overall greenhouse gas emissions.However, challenge lies in converting technical lignin polymer from biorefinery directly to a continuous operation.In this work, we demonstrate simultaneous depolymerization and hydrodeoxygenation (SDHDO) process produce ligninbased alkali corn stover (ACSL) using engineered Ru-HY-60-MI catalyst flow reactor, for first time.The...
It has long been understood that phase changes are one way to accomplish separations of mixtures, and for liquid the process freezing followed by a thaw results in high degree purification final component mixture melt. This thaw, into mixture, occurs at lower temperature than freeze/melting point highest-freeze-point component. As such, freeze is dependent on therefore, it generally unknown arbitrary mixtures along with associated change properties such as enthalpy entropy fusion. In this...
Sustainable aviation fuel pathways do not generally yield selective synthetic blend components in the turbine distillation range. Here we discuss a methodology for maximizing sustainable from pathway and respective ratio with petroleum-derived by varying cut points. These points are typically unique each combination of feedstock conversion technology essential independent variables finishing. The resultant point variations create Pareto front, illuminating competition between limits, i.e.,...
Abstract In this study, systematic soil methane cycle geochemical monitoring was carried out in a typical gas hydrate region the Qinghai-Tibet Plateau.

Six hundred and seventy-five measurements of dynamic viscosity density have been used to assess the prediction error Arrhenius blending rule for kinematic hydrocarbon mixtures. Major trends within data show that mixture complexity–binary hundreds components—and temperature are more important determinants than differences in molecular size or hydrogen saturation between components Over range evaluated, no correlation mole fractions was observed, suggesting log truly is linear fraction, as...
