Summary: The pyrolysis characteristics of Spirulina platensis, Tetradesmus obliquus, and Chlorella vulgaris were investigated by various techniques. The elemental and biochemical composition of different microalgae influenced their pyrolysis behavior. The pyrolysis process of the three microalgae could be divided into several stages, and the major reaction occurred at a certain temperature range. Different products and activation energies were observed for each microalgae. The pyrolysis of Spirulina platensis produced more CO2 and compounds containing C=O bonds, while Tetradesmus obliquus and Chlorella vulgaris produced slightly higher levels of hydrocarbons.

Summary: This study investigated the pyrolysis kinetics and pyrolytic products distribution of coal slime and compared it with raw coal. The results showed that the pyrolysis of coal slime consists of three reaction stages, with the decomposition of volatiles as the main stage. The presence of inorganic minerals significantly influenced the pyrolysis reaction, and the alkene content of pyrolysis products decreased while the contents of CO2 and aromatics increased in coal slime compared to raw coal. These findings provide theoretical and practical guidance for the efficient thermochemical conversion and utilization of coal slime.

Summary: This study investigated the effects of anaerobic digestion pretreatment on the pyrolysis characteristics of Sargassum. The results showed that increasing the anaerobic digestion duration decreased the content of extract and cellulose, while increasing the content of lignin in Sargassum. The fiber crystallinity and specific surface area of Sargassum were increased due to changes in chemical composition. Anaerobic digestion also affected the gaseous and liquid products of pyrolysis, enhancing the thermal stability of Sargassum. The composition and structure of the biomass were altered, affecting the quality of the pyrolytic products.

Summary: The study reveals that compared to DBC, DOM contains a higher percentage of tannin-like/condensed aromatic compounds and higher average conditional stability constants (logK(Cu)). The molecular components of 200-320 Da and 320-480 Da in DBC/DOM significantly contribute to the logK(Cu) values of UVA and visible fluorescent components, respectively, with nitrogenous groups likely exhibiting stronger binding affinities than phenolic/carboxylic groups.

Summary: This study proposes a covariant evolution mechanism to explain the emission characteristics of VOCs and RFGs during biomass pyrolysis. Using online measurement and two-dimensional correlation spectroscopy, it is found that the relative percentages of CS/WP-VOCs are higher than those of SBC-VOCs, and VOCs tend to have smaller carbon skeletons as the carbon oxidation state increases. The study also reveals a corresponding relationship between the sequential responses of VOCs and RFGs during CS/WP pyrolysis. Compared to CS/WP, the gas-solid products from SBC pyrolysis exhibit complex temperature-dependent responses and high oxidation-induced variability.

Summary: This study investigated the photodegradation mechanisms of pyrogenic dissolved organic matter (pyDOM) at the molecular scale, revealing differences in the molecular changes and reactive oxygen species generation of pyDOMs under continuous irradiation, depending on feedstock type and pyrolysis temperature. The results showed that higher aromaticity, molecular variety, and lower unsaturation were observed in pyDOM450 compared to pyDOM300. Additionally, the degradation pattern of pyDOMs was found to have two distinct stages, with different degradation ratios between pyDOM300 and pyDOM450 after 720 hours of irradiation. This study contributes to a better understanding of the cycling and environmental effects of pyDOMs.
