Method & Evidence

AimTo characterize the fuel properties and determine the calorific value of briquettes produced from five different varieties of corn cob after carbonization.
MethodExperimental analysis
ProcedureCorn cobs were carbonized in a reactor with limited air supply and ventilation holes. The resulting charred product was crushed, ground, and formed into briquettes. These briquettes were sun-dried, and their properties, including calorific value (Higher Heating Value - HHV), were measured using standard methods.

Paragraph starter

Research into biomass energy has demonstrated that processing agricultural waste, such as corn cobs, can significantly enhance their utility as a fuel source. For instance, a study by Birhanu Oliy and Tesfaye Muleta (2020) found that carbonizing and briquetting corn cobs resulted in calorific values ranging from 27.60 to 29.67 MJ/Kg, indicating a substantial improvement over raw material. This suggests that material transformation techniques are crucial for unlocking the energy potential of waste streams.
