✦ Synopsis

The feasibifity of converting cocoa tree pmnings into charcoal was assessed. Carbonisation was done at terminal temperatures of 400-550°C with holding times of 1-3 h and at a constant heating rate of 5°C/min. The holding time had no significant effect on either the yield or the quafity of charcoal produced. However, as terminal temperature increased, both yield and volatile content decreased, while the fixed-carbon content as well as calorific value increased. The ash content (average 10"95%) was, however, not affected by holding time or terminal temperature. The results indicated that charcoal of acceptable quality can be produced from cocoa tree prunings.
