  The main objective of this present study was to investigate the Torrefaction process of lignocellulose biomass ricehusk produced in Ethiopia through dry and chemical treated Torrefaction. Torrefaction is a technology that a partialpyrolysis of biomass which is carried out under atmospheric pressure in a narrow temperature range of 200-300°Cand under an inert environment which yields higher solid yield than pyrolysis. Three different Torre factiontemperatures 230, 255 and 280°C with three different holding times 20, 40 and 60 minutes were considered usingdry and chemical treated torrefaction. The result showed that a net reduction of the volatiles content, mass yield,moisture content, bulk density and atomic oxygen content correlate with increasing torrefaction temperature andreaction time, while atomic carbon content, higher heating value (HHV), fixed carbon content and energy..
