Development of Antifreezing High‐Efficiency Dust Suppressant for Railway Coal Transportation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the process of railway coal transportation, a large amount of coal dust is dispersed, causing serious economic loss and environmental pollution. In order to improve the low‐temperature dust suppression performance, the present study has developed an antifreeze‐type, high‐efficiency railway coal transportation dust suppressant (hereinafter ...

Evaluation of Air Inlet Configuration's Effect on Biochar Properties From African Mesquite Pod Carbonization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The suboptimal efficiency of current biomass conversion processes necessitates the optimization of biochar production methodologies to enhance desired biochar characteristics. In this study, an investigation was conducted to determine the optimal air inlet configuration within a top‐lit updraft gasifier system for enhancing biochar properties ...

Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...

Homologous Bio‐Tar and Bio‐Tar Pitch as Co‐Carbonization Agents in the Preparation of Mesophase Pitch

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The present work systematically compares the performance differences between two novel homologous materials employed as co‐carbonization agents in the synthesis of mesophase pitch. Low‐cost FCC slurry was used as the raw material, with bio‐tar (BT) and bio‐tar pitch (BTP) as co‐carbonization agents.
