In this work, a comprehensive process model for pyrolysis of palm empty fruit bunch, bio-oil upgrading, and electric power generation can predict the production under various operating conditions. This work proposed a kinetic reaction model of 149 individual reactions. Palm empty fruit bunch was used as a feedstock for pyrolysis at 500 oC. The upgraded bio-oil to gasoline and diesel via hydrotreating process was implemented by a pseudo-first order reaction of lumped bio-oil species followed by the hydrocracking. Dry Empty Fruit Bunch can produce 67.25% of bio-oil, 21.37% of gas, and 11.38% of char. The bio-oil upgraded at 1 kg of wet empty fruit bunch can produce 0.053 kg of gasoline and 0.069 kg of diesel. Electricity generation in the pyrolysis and the upgrading can save electricity up to 72%. The energy conversion efficiency of the pyrolysis combined with the upgrading step was 57.38%. Therefore,  this work is a suitable option for biofuel production from empty fruit bunch.
