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: The fast pyrolysis behavior of mushroom bran (MB) and corn straw (CS) with high ash and high nitrogen content was studied using high heating rate TG-FTIR and PyGC/MS. The study found that at higher heating rates, there is an overlap of the decomposition of starch and hemicellulose, potentially promoting the formation of furan and furfural. Nitrogen tends to migrate from hydrogen cyanide to NH3 before 450 degrees C. Deoxidation and denitrification primarily occur between the pyrolysis temperature range of 300 degrees C to 350 degrees C. Staged pyrolysis interrupts the oil's continuous deoxidation process, and it reduces the selectivity of aldehydes and ketones in MB and CS pyrolysis. This study provides detailed pyrolysis characteristics for high nitrogen and ash content biomass.

Summary: This study investigates the pyrolysis performances and reaction kinetics of pine needles using thermogravimetric analysis, Fourier transform infrared spectroscopy, and pyrolysis-gas chromatography/mass spectrometry. It was found that pine needles showed higher pyrolysis efficiency at lower heating rates, while increased heating rates promoted the reaction. The activation energies of hemicellulose, cellulose, and lignin were calculated to be 156, 165, and 172 kJ/mol, respectively, using the King-Kai method. The main pyrolytic by-products identified were hydrocarbons, phenols, alcohols, ketones, and aldehydes. This study demonstrates the significant potential of pine needles as a suitable source for bioenergy.

Summary: This study aimed to investigate the co-pyrolytic synergistic effects of textile dyeing sludge (TDS) and waste biochar (WBC) for optimal resource utilization and environmental mitigation. Results showed a strong synergistic effect between TDS and WBC in the presence of CO2, particularly between 800 and 900 degrees C. Increasing the TDS fraction led to a significant reduction in NH3 emissions. Co-pyrolysis transformed certain harmful compounds into more stable forms and inhibited the formation of S-containing compounds.

Summary: The co-combustion of textile dyeing sludge (TDS) and cattle manure (CM) can enhance resource circularity and pollution control. However, the migration and transformation behaviors of ashes during this process are still unclear. This study used thermogravimetric experiments and thermodynamic simulations to investigate the transformation and migration of co-combustion ashes and the interactions involved. The addition of TDS increased the environmental safety of Ni and Cr by transforming them from extractable form to stable form. P dominated S in the reaction with Ca, promoting the emission of S-containing gases and the generation of apatite P. The reactions between minerals in CM and Ca in TDS resulted in the formation of calcium silicate, reducing the S-fixation ability of Ca and increasing the emission of S-containing gases. These findings provide insights into the interactions among minerals, heavy metals, and specific elements, and their impact on pollutant emissions, thus enhancing pollution control strategies.

Summary: This study explores the effects of HCl and H3PO4 pretreatment on the physi-chemical properties and decomposition characteristics of an As-hyperaccumulator. The results show that HCl pretreatment retains the main components of the hyperaccumulator while introducing Cl to the carbon chain, while H3PO4 pretreatment destroys the carbon chain and removes more organics and minerals. HCl pretreatment improves the pyrolysis efficiency, while H3PO4 pretreatment decreases leaching of heavy metals. These findings provide valuable insights for the management and utilization of post-harvest hyperaccumulators.
