Abstract

The pyrolysis characteristics of cake from whole, kernels and crushed jatropha seed (Charcoal yield, fixed Carbone content, mineral matter) were assessed. The pyrolysis process consisted in introducing into an oven, at 300°C for 15 minutes, a 25 ml ceramic crucible containing 5 g of cake (2% water content) coated in pre-weighed aluminum foil. The main results were as follow. The highest charcoal yield (75,76±1,53%) was obtained with cake from crushed seeds preheated at 100°C associated to the extraction pressure of 15000 pounds. The highest fixed Carbone (18,64%) was registered with biochar from kernels cake obtained at the preheating temperature/extraction pressure couple of 25°C-15000 Pounds. The highest mineral matter content (Mg, Ca, P and K) are recorded in charcoal from the kernel cake pyrolysis. Seed form significantly affected the cake yield and biochar yield. The pH of jatropha biochar (7,5-10) are alkaline which can be useful for acid soil fertilization in Cameroon.
