Özet
The current study provides a dedicated assessment of recent co-gasification studies, comparing them quantitatively in terms of hydrogen yield and syngas heating value. The main objective of this process is to propose a hydrogen- oriented framework to support process synthesis and design. The literature is organized into three main approaches including experimental studies, thermodynamic equilibrium modeling (Gibbs free-energy minimization), and kinetic modeling. The strengths and limitations of each approach are summarized for co-gasification systems. Key design variables including plastic type, gasifying/oxidizing medium, bed material, blending ratio, and operating conditions are examined with a particular emphasis on translating the findings into practical, actionable guidelines. The results of the current review study show that the general hydrogen yield trend from high to low can be ordered as HDPE (high-density polyethylene), LDPE (low-density polyethylene), PP (polypropylene), PET (polyethylene terephthalate), and PS (polystyrene). Most systems indicate a practical operating range of roughly 750–900 °C, balancing enhanced hydrogen formation and syngas heating value with acceptable tar levels. Regarding the gasifying medium, steam gasification is highlighted as more advantageous for boosting hydrogen yield compared with air or oxygen-diluted cases. Finally, bed materials play a decisive catalytic role. Olivine can substantially increase H2/CO and reduce tar, while dolomite often yields a more hydrocarbon rich gas with comparatively high LHV.
