• Resumen

  • Cocoa tree prunings were carbonised at terminal temperatures of 600–800°C with a holding time of 1 h and at a constant heating rate of 5°C min−1. As terminal temperatures increased, both yield and volatile content of the charcoal produced decreased while that of the fixed carbon content increased. The ash content decreased slightly for the terminal temperature range of 600–700°C. Improvements in charcoal quality were insignificant after achieving a carbonisation temperature of about 650–700°C.
