The adverse impact of fossil fuels' on the environment and the increasing concerns regarding climate change, have intensified research efforts towards the exploitation of renewable energy sources (RES). Biomass can be utilized as a CO2-neutral fuel in several energy conversion technologies. For instance, biomass gasification converts solids to syngas, which can be directly used as a fuel or as a valuable building-block toward synthetic liquid fuels and/or chemicals. The scope of the present study is the simulation of a combined process that exploits olive kernel (OK, 833 kg/day) for the production of electrical power and bio-oil. The integrated process includes: a) the slow pyrolysis of the olive kernel at 500 οC to solids (biochar, 252 kg/hr), liquids (336 kg/hr) and non-condensable gases (245 kg/hr), b) the autothermal gasification of biochar to syngas (1126 kg/hr) and c) the direct utilization of syngas in a solid oxide fuel cell (SOFC), for the cogeneration of electrical (1.35 MWel) and thermal (1.1 MWth) power. The combined process approaches a 50 % electrical efficiency, upon the raw biomass lower heating value (LHV). The integrated process was simulated using Aspen Plus® software and based on the experimental results of a previous study.
