Dispersed dyed polyester (PET) fabrics was decolorized in a laboratory-scale ScCO₂ system with pristine PET serving as a dye absorbent guided by the principle of ScCO₂ dyeing. The influence of key process parameters such as time, temperature, pressure, and dyed-to-absorber fabric loading on extraction efficiency was analyzed through the equilibrium constant for dye partitioning. Results revealed that PET fabrics treated at 10:90 dyed-to-absorber loading under 120 °C, 25 MPa for 60 min exhibited the highest decolorization efficiency of (79 – 85) % for all dyes, reflected by the lowest color strength (K/S) values of 0.93 – 2.46. The equilibrium constant (Keq) increased with temperature, pressure, and absorber loading, reflecting improved dye partitioning efficiency. In an attempt to predict the thermodynamic behavior waste textile decolorization using ScCO₂, Peng-Robinson Equation of State (PR-EOS) was used to model the behavior and correlated with experimental values. Results showed modest qualitative agreement with experimental data with an AARD of 27–32 %.

Molecular docking demonstrated stable interactions between most bioactive components and core targets through hydrogen bonds, with binding energies predominantly less than −5 kcal/mol.

The findings reveal that flow conditions transform the dominant corrosion mode in the phase transition environment from pitting corrosion in static conditions to uniform corrosion in dynamic conditions.

Most droplets become smaller than the critical radius required for downward pit propagation, leading to lateral pit expansion rather than deepening.

Accordingly, fluidized bed reactors using supercritical fluids (SCFs) as fluidizing agents have attracted considerable attention in recent years due to their unique physicochemical properties. Supercritical fluidized beds offer higher fluidization uniformity, reduced bubble diameter, improved particle mixing, and greater bed expansion compared to conventional gas-solid FBs. This review comprehensively examines the advancements in supercritical fluidization technology, with emphasis on supercritical water and carbon dioxide. The main findings indicate that operational parameters, including temperature, pressure, and superficial fluid velocity, exert a substantial influence on fluidization characteristics by modulating the properties of the SCF. Particle properties, including diameter, shape, and size distribution, significantly affect minimum fluidization velocity, bubble dynamics, and bed homogeneity. Predictive correlations for critical parameters are discussed, highlighting their role in reactor design and optimization. Despite notable progress, challenges persist, such as limited experimental data and the limited applicability of traditional fluidized bed testing methodologies to the supercritical domain.
