Abstract

The paper is focused on upgrading of Palm oil empty fruit bunches (EFB) pellets by using rapid torrefaction process. This study aims to evaluate the effects of torrefaction on the main energy properties of EFB pellets. The torrefaction process was conducted on range temperature of 250-350 ˚C by using COMB (Counter Flow Multy-Baffle) Reactor with 3 minutes of residence time. The properties of raw pellets and torrefied pellets such as the caloric value, energy density, ash content and mineral compositions, fixed carbon, volatile materials, lignin, holocellulose, extractives, and water immersion of pellets were analyzed in order to study the effect of torrefaction process on the pellets properties changes. The analytical results showed that the initiating heating value and carbon content of raw EFB pellet are 15.82MJ/kg, and 47 .24 % increased up to 16.20 MJ/kg. 17.90 MJ/kg, 47.70 and 62,06 wt%d.b, subsecquentially for brown and black pellets. In case of moisture content, the initial EFB pellets has 9.21% decreased up to 8.97, and 7.80 %, subsecquentially for brown and black pellets. The obtained results revealed significant differences for all of main physical and energy properties of pellets. The torrefaction is able to upgrade the EFB pellets which having higher caloric value, carbon content, and lower water adsorption.. Therefore, the torrefied EFB pellets are potential to apply as a solid fuel for gasification feedstock or others thermal applications.
