Summary: In this study, diffusion rates of three gases (CO2, N-2, and normal hexane) in ABS were measured. A diffusion model was proposed to estimate the diffusion coefficients based on the specific volume and chemical potential of the gases. The solubility and diffusivity of the gases in ABS were determined experimentally. The results showed that solubility and diffusivity increased with increasing pressure, and N-2 had the lowest solubility and highest diffusivity in ABS. The proposed model successfully predicted the diffusion coefficients of the gases in ABS.

Summary: This paper studied the explosion properties and pyrolysis mechanism of ABS dust during processing, as well as the inhibitory effects of sodium bicarbonate (NaHCO3) on ABS dust. The results showed that NaHCO3 effectively reduced the ignition sensitivity and explosion severity of ABS dust by increasing its mass fraction. Adding 50 wt% NaHCO3 could mitigate the explosion hazard to an acceptable level. The incorporation of NaHCO3 enhanced the heat stability of ABS dust, interrupted the combustion chain reaction, and inhibited the propagation of the explosion.

Summary: The presence of fly ash increases both the deposition amount and the temperature of ABS in the 25-200 ppm SO3 concentration range. The main product formed was ABS, and its formation temperature was much higher than the deposition temperature observed in the experiment. The products gradually changed from ABS to sulfuric droplets in the 224-180 degrees C range.

Summary: This study investigated the characteristics of sewage sludge and coal slime combustion, finding that co-combustion had a positive effect on desulfurization. Proper blend ratios and temperatures could effectively suppress the emission of SO2. The evolution of S functional groups showed different patterns during co-combustion. Calcium played an important role in the process, reacting with SO2 to form intermediate solid products and retaining SO2 in the ash.

Summary: The heating rate has a significant impact on the pyrolysis process, especially for reactions involving the co-pyrolysis of biomass and plastic. The synergistic effects of the blend samples are concentrated in the main decomposition region, and the co-pyrolysis process requires less activation energy compared to the pyrolysis of plastic alone.

Summary: This study investigates the pyrolysis of antibiotic mycelial residue (AMR) at different temperatures and heating rates to produce valuable biochar for heavy metal immobilization. The results show that the decomposition of AMR involves three pseudo-reactions that fit a three-dimensional diffusion model. Increasing the pyrolysis temperature and heating rate reduces the yield and volatile matter content of the biochar, but increases the ash content, fixed carbon content, and aromaticity. The AMR-derived biochar demonstrates favorable fuel properties and stability against soil degradation, making it a valuable carbon resource.

Summary: In this study, a hydrothermal-carbonization method was utilized to process waste biomass, resulting in the production of high-value carbon aerogels. The banana peel-based carbon aerogel showed the best performance in ethanol cracking, achieving a hydrogen yield of 41.86%. The enhanced ethanol cracking was attributed to the abundant pores in the carbon aerogel, which extended the residence time, and the presence of inorganic components (such as Ca, Mg, and K) on the surface of the aerogel, which promoted bond-breaking and reorganization in ethanol.

Summary: Novel copper-doped zirconium-based MOF (UIO-66) and copper-doped iron-based UIO-66 catalysts were prepared to improve the removal performance of gaseous benzene. The catalysts were characterized using various techniques, and it was found that the bimetal Cu/Fe modification had a positive effect on the morphology of the catalyst particles. The factors of different metal loading, dose of H2O2, and reaction temperature were studied, and it was observed that Cu-1.5/Fe-1.5@UIO-66 achieved the highest benzene removal efficiency of 94.6%. The study also provided insights into the activation mechanism of the catalyst and its potential application in treating benzene pollutants in waste gases.

Summary: This paper investigates the co-combustion characteristics and NO/SO2 emission behavior of sewage sludge (SS) and coal slime (CS). The study reveals significant interactions between SS and CS during co-combustion and explores the mechanisms behind these interactions. The results demonstrate the influence of both non-catalytic factors and catalytic factors on the combustion characteristics, and the effect of co-combustion temperature and CS ratio on NO and SO2 emission characteristics. The findings also shed light on the reduction of NO facilitated by reducing gases released by SS combustion and the reduction of SS-NO by char formed by CS.
