Summary: In this study, laser desorption ionization (LDI) and collision-induced dissociation (CID) experiments were introduced as effective tools for characterizing asphaltene structures. These tools facilitated the analysis of asphaltene samples enriched in different structures and proposed corresponding structures. Additionally, correlations between asphaltene structures and their stability were attempted to be established through calculating the relative percentages of product ions.

Summary: This study analyzed the pyrolysis heavy components from 4-hydroxy benzaldehyde and vanillin at a molecular scale for the first time using FT-ICR-MS, revealing the evolution of different functional groups and pathways. Aldehyde groups were found to promote the formation of heavy components with more aromatic rings, while methoxy groups could compete for linking positions.

Summary: This study provides insights into the characteristics of nitrogen-containing compounds during protein-rich spirulina platensis pyrolysis in a ternary eutectic carbonate. The results show that molten carbonate significantly reduces the nitrogen-containing compounds content in bio-oil and heavy bio-oil, and plays an important role in the depolymerization and conversion processes.

Summary: A large volume of scrap tires are produced worldwide daily, and landfill is an ineffective method of disposal. Pyrolysis can convert tire rubber into energy, allowing for waste management in a circular economy. The use of alkali carbonates as catalysts in pyrolysis tests improves the thermal degradation rate and can tailor the distribution of pyrolysis products.

Summary: The alkali/alkaline earth metal species (AAEMs) in biomass significantly affect the formation of heavy components in bio-oil during pyrolysis, promoting the breakage of active oxygen-containing functional groups. The catalytic effects of K and Ca differ, with K showing a stronger decomposition effect on large molecular weight compounds in heavy components compared to Ca.

Summary: Dissolved Organic Matter (DOM) is a significant component of the global carbon cycle. This study used high-resolution mobility and ultrahigh-resolution Fourier transform ion cyclotron resonance tandem mass spectrometry (FT-ICR MS/MS) to compare four solid phase extracted (SPE) DOM samples from three freshwater ecosystems. Comparison of structural families revealed dissimilarities in the structural footprint of the samples. Inclusion of isomeric content in the structural family description suggested additional transformation pathways and/or source variations.

Summary: This study investigated the photochemical properties of dissolved organic matter (DOM) with different molecular weights. The results showed that the low molecular weight fraction exhibited higher formation rates and quantum yields of reactive oxygens. The presence of humic-/fulvic-like substances and protein-/lipid-derived compounds in the low molecular weight fraction may contribute to the high photochemical potential of DOM.

Summary: The evolution paths of heavy compounds during pyrolysis of biomass components were influenced by temperature, with phenolic-like substances being the most active during secondary reactions. Increasing temperature promoted secondary reactions of phenolic-like species while inhibiting reactions of hemicellulose. Lignin-derived lipids and unsaturated hydrocarbons increased with rising temperature, showing more complex evolution paths compared to cellulose and hemicellulose.

Summary: Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been widely used to analyze the molecular composition of dissolved organic matter (DOM) in different ecosystems. This study compared 67 DOM samples from various ecosystems, revealing significant variations in the molecular composition of DOM among different ecosystems. The results provide insights into the biogeochemical cycling of DOM and highlight the need for a comprehensive molecular fingerprint database of DOM across a wider range of ecosystems.

Summary: The hydrotreating of scrap tires pyrolysis oil over commercial Ni-Mo/Al2O3 catalyst was investigated to produce high-quality alternative transportation fuel components. Despite the initial high content of olefins, aromatics, sulfur, and nitrogen, the fuel components obtained after hydrotreating met most fuel specifications. The different fractions of the oil can be used as gasoline, jet fuel, diesel, and marine fuel components by applying additional treatments or blending methods.

Summary: Understanding the composition and transformation of dissolved organic matter (DOM) in river systems is crucial for predicting the impact of human activities. This study used advanced techniques to analyze the chemical differences of DOM collected from different regions in the Changjiang basin. The results showed that land-use practices and human activities significantly influenced the quality and composition of DOM, and seasonal variations also played a role in altering the DOM composition and riverine carbon flux in anthropogenically disturbed river systems.

Summary: This study characterized the nitrogen compounds in the full distillation range of waste tire pyrolysis oil using various detection methods. It found that the nitriles in the light fraction may originate from amides in the heavy fraction. The nitrogen transformation during the pyrolysis of waste tires was suggested based on quantum chemistry simulations, which could help in the treatment and removal of undesirable nitrogen compounds in waste tire pyrolysis oil.

Summary: Hydrogen peroxide pretreatment was applied for fast pyrolysis of corn stalks, and it was found that the pretreatment effectively promoted lignin depolymerization and decreased the reaction activation energy. The pretreatment also increased the cellulose content and removed alkali and alkaline earth metals from the biomass. The pH of the hydrogen peroxide solution affected the removal of lignin and ash by the pretreatment, and the composition of bio-oil changed significantly, with a significant increase in the relative content of levoglucosan after pretreatment.
