Experimental data on morphological characterization of chars from coal and bagasse blends

Area of Science:

• Combustion Science
• Materials Science
• Biomass Pyrolysis

Background:

• Char morphology significantly impacts combustion efficiency and reactivity.
• Understanding char structure from diverse feedstocks like coal and bagasse is crucial for energy applications.
• Previous research highlights the importance of char characteristics in combustion processes.

Purpose of the Study:

• To present comprehensive data on the morphology of chars derived from coal-bagasse blends.
• To investigate the influence of pyrolysis temperature and bagasse proportion on char morphology.
• To classify char morphologies into distinct categories for further analysis.

Main Methods:

• Chars were synthesized via pyrolysis of coal-bagasse blends at temperatures of 900, 1000, and 1100 °C.
• Bagasse proportions in the blends were varied systematically (0, 25, 50, 75, and 100% w/w).
• Characterization included proximate, ultimate, petrographic analyses, and vitrinite reflectance of raw materials and synthesized chars.

Main Results:

• Detailed morphological data for chars produced from various coal-bagasse blends are presented.
• Char morphology was classified into three main types: thin walls, thick walls, and solid particles.
• The study provides a comprehensive dataset correlating feedstock composition and pyrolysis conditions with resulting char structures.

Conclusions:

• The generated dataset serves as a valuable resource for understanding char morphology in coal-bagasse systems.
• This research advances the knowledge base for optimizing the combustion behavior of biomass-coal blends.
• Further studies can leverage this data to improve combustion efficiency and reduce emissions.
