This paper describes the effect of torrefaction on the characteristics of empty fruit bunches (EFB) and palm kernel shell (PKS).The torrefaction of EFB and PKS was investigated in a horizontal tubular reactor at a temperature ranging from 150to 600 degrees C, for torrefaction residence time varying from 0 to 50 min. The t orrefied products were characterized in terms of their elemental com position, energy yield, ash content and volatile fraction. The presen t study developedthe torrefaction kinetics of EFB and PKS in a thermogravimetric analyzer to obtain the kinetic parame ters. EFB and PKS exhibited excellent energy yield values. The gaseou s products from torrefaction of EFB and PKS were also analyzed. Further more, the study reveals that the carbon content increases with an incre asing torrefaction temperature but the O/C ratio, hydrogen an d oxygen content decrease for both EFB and PKS. The energy yield and mas s yield were found to decrease with an increase in the torrefaction temperature while the higher heating value (HHV) increased. From t his study, torrefaction temperature between 290 and 320 degrees C is the optimum torrefaction temperature for EFB while torrefaction te mperature between 300 and 320 degrees C is the optimum torrefaction temp erature for PKS.
