Summary: This study investigates the influence of platinum loading on the hydrogenation of polycyclic aromatic hydrocarbons (PAHs) in pyrolysis fuel oil (PFO) using Pt/gamma-Al2O3 catalysts for producing jet fuel. Catalyst characterization was carried out through nitrogen adsorption, temperature-programmed desorption of ammonia, and temperature-programmed reduction under hydrogen flow. The catalytic performance of bead-type Pt/gamma-Al2O3 catalysts in the hydrogenation of PAHs in PFO-cut was evaluated in a trickle-bed reactor. The main products of the hydrogenation reaction include decalin derivatives, alkylated cyclohexane, hexahydroindan derivatives, and bicyclohexyl. The Pt(1.0 wt%)/gamma-Al2O3 catalyst exhibited the highest activity and negligible deactivation over ten hours of time-on-stream.

Summary: This study aimed to develop a general heterogeneous multiscale model for continuous trickle bed reactors, enabling calculation of concentration and temperature changes as well as the stationary behavior. The model simultaneously solved energy and mass balances for both gas and liquid phases, as well as stagnant catalyst particles. Well-established correlations for mass transfer coefficients and pressure drop equations were used. The model is general and can be applied for other bed reactors and arbitrary reaction schemes. Simulation results showed that complete sugar conversion was achieved only for small catalyst particles, and the reactor length had a greater impact on arabinose conversion than residence time or bed radius.

Summary: This study proposes an efficient separation of Au(iii)/Pd(ii)/Pt(iv)/Rh(iii) using a cloud point extraction system with 2-mercaptobenzothiazole-functionalised ionic liquid ([C(6)mim][2MBT]). The direct cloud point extraction of Au(iii) was achieved without any functionalised ionic liquids. Addition of [C(6)mim][2MBT] greatly enhanced the extraction performance of Pd(ii). However, preconcentration of Pt(iv) and Rh(iii) required the addition of stannous chloride, which can be adjusted by changing the hydrochloric acid concentration.

Summary: The flow behavior of liquid film in trickle bed reactors was studied, revealing that liquid tends to accumulate on the contact point between adjacent particles. Increasing the liquid inlet flow rate can improve both the wetting ratio and thickness of the particle surface wetted by the liquid film, while increasing the wettability of the particle surface only improves the wetting ratio, with little effect on the liquid film thickness.

Summary: This study investigates Pt/Rh and Pd/Rh-based three-way catalysts under various transient conditions in natural gas engines. The results show that Pt/Rh catalyst is more effective for methane direct oxidation under lean conditions at high temperatures, while both catalysts can trigger methane steam reforming. The essential role of Rh in NOx conversion and high N-2 selectivity is confirmed.

Summary: This study presents an efficient method for remediating DEHP-contaminated marine sediments using water hyacinth biochar (WHBC) as a carbocatalyst activated by calcium peroxide (CP). The catalytic capacity of WHBC was significantly influenced by the pyrolysis temperature. The WHBC/CP system achieved a 94% removal of DEHP, with singlet oxygen (1O2) and electron-rich carbonyl functional groups playing crucial roles in the non-radical activation of CP. Moreover, WHBC showed lower cytotoxicity in HepG2 cells and induced cell cycle arrest at the G2/M phase.

Summary: The effect of pyrolysis atmosphere (CO2 or N2), pyrolysis temperature (300-900 degrees C), and heteroatom (N, B, O, P, NP, or NS) doping on the content of polycyclic aromatic hydrocarbons in pineapple leaf biochar was investigated. Without doping, the highest polycyclic aromatic hydrocarbon production (1332 +/- 27 ng/g) was observed in CO2 at 300 degrees C, while the lowest (157 +/- 2 ng/g) was observed in N2 at 700 degrees C. The main components, naphthalene and acenaphthylene, accounted for about 91% of the total polycyclic aromatic hydrocarbon in biochar produced under CO2 at 300 degrees C. Doping significantly reduced the total hydrocarbon content, with reductions of 49% (N), 61% (B), 73% (O), 92% (P), 93% (NB), and 96% (NS) under the conditions of maximal polycyclic aromatic hydrocarbon production (CO2, 300 degrees C). The findings highlight the importance of controlling pyrolysis atmosphere, temperature, and heteroatom doping for the management of polycyclic aromatic hydrocarbons in biochar production and contribute to the development of circular bioeconomy.
