“…They proposed multi-component surrogates and compared the prediction of the surrogates' models with the measured IDTs of the three blends. In a separate work, Wang et al [44] measured IDTs of the three surrogates proposed previously and compare them with the predictions of the surrogate models.…”

“…After the contamination of soil with diesel, the TOC content from raw soil (1.53 ± 0.85 g kg −1 ) shifted up to 34.77 ± 1.74 g kg −1 in contaminated soil. According to literature reports, the total petroleum hydrocarbons (TPHs) content established for diesel oil is 86 %, considering the carbon content in molecules 28, which is relative to the paraffin fractions of oil (C 10 H 22 to C 20 H 42 ), excluding alicyclic/aromatic/olefin hydrocarbons. Moreover, it is assumed that the paraffin content present in diesel ranges between 74.0 % and 74.3 % 28, 29.…”

Diesel‐contaminated soil was treated with Fenton's oxidant, from hydrogen peroxide. Soil samples were collected during the earthmoving of RNEST Oil Refinery (Petrobras). A factorial design 33 evidenced that the concentration of iron ions [Fe2+] was the variable with the most statistically significant effect in all experiments. The oxidation efficiency was found to be 57 % of total organic carbon (TOC) and 78 % of polycyclic aromatic hydrocarbon (PAH) removal. Moreover, the sum of low‐molecular‐weight PAHs on treated soil and the sum of high‐molecular‐weight PAHs was determined. Soil remediation in a pilot‐scale reactor led to a reduction of nearly 80 % in total PAHs. Toxicity assessment with Californian red earthworms as bioindicator evidenced the mineralization of PAHs.

3-Pentanol is a potential alternative fuel or a green fuel additive for modern engines. The H-abstraction reactions from 3-pentanol by H, CH 3 , HO 2 , and OH radicals are significant in the 3-pentanol oxidation process. However, corresponding rate constants are forced to rely on either analogy from sec-butanol or estimation from alkanes due to a lack of direct experimental and theoretical study. In this work, stationary points on the potential energy surfaces (PESs) were calculated with the high-level DLPNO-CCSD(T)/CBS(T-Q)// M06-2X/cc-pVTZ method, which is further used to benchmark against the CBS-QB3 method. Then, the high-pressure limit rate constants for target reactions, over a broad range of temperature (400−2000 K), were calculated with the phase-space theory and conventional transition state theory. A comparison was made between the calculated rate constants and the values available in Carbonnier et al. [Proc. Combust. Inst. 2019, 37(1), 477−484]. The rate constants for the above H-abstraction reactions in the Carbonnier model were updated with the calculated results, followed by a modification based on the computed results of 3-pentanol + HO 2 to obtain the revised model. Validation against the shock tube (ST) and the jet-stirred reactor (JSR) measurements from the literature proved the revised model an optimal one. Furthermore, using an ST, ignition delay times (IDTs) for the 3-pentanol/air mixtures were measured spanning a temperature range of 920−1450 K, pressures of 6, 10, and 20 bar, and equivalence ratios of 0.5, 1.0, and 1.5. Generally, IDTs decrease with increasing temperature and reflected shock pressure. Improved predictions to present experimental data were obtained by using the revised model as compared with the Carbonnier model. Finally, sensitivity analysis was conducted using the revised model to gain an in-depth comprehension of the 3-pentanol autoignition.
