Abstract. Pyrolysis experiment was conducted at operational temperature of 300 -500 o C, 2h retention time, 10 o C heating rate and N 2 flow rate of 2L/min on palm kernel shell (PKS), empty fruit bunch (EFB) and mesorcop fibre(MF) with an objective to classify the potential applications of bio-chars, precisely for coal replacement application. From the results obtained, the bio-char produced show the potentiality to be used as a fuel, soil improvement substance and in activated carbon applications. All the three bio-chars from MF, PKS and EFB could serve as a fuel and soil improvement applications, but for activated carbon applications such as coal replacement, PKS and MF bio-chars could be better because they produced bio-chars with excessive amount of fixed carbon contents (36.89 -61.67 wt % and 37.63 -59.11 wt % respectively) near anthracite coal than EFB.
