The environmental concerns of the society to reduce the pollutants in earth and the greenhouse gases (GHGs) has inspired the research community to substitute the fossil fuels with renewable energy sources like biomass. The fast pyrolysis process is a promising conversion route to utilize biomass and produce biooil and electrical power. The bio-oil produced from the fast pyrolysis is a versatile feedstock that can be used as a heating-oil or bio-fuel through its upgrade and finally produce a similar bio-fuel with fossil fuels based. Lately, further researches are carried out in order to utilize it as a feedstock of producing valuable chemicals or biodegradable chemicals and substitute those coming from fossil fuels. The bio-oil is a promising intermediate product with a lot of potential. In this thesis a comparative study was carried out via the catalytic and non-catalytic pyrolysis processes based on experimental data retrieved from the Chemical Process & Energy Research Institute Center in Thessaloniki, Greece and along with the Luleå University in Sweden. As a feedstock, it was used lignin derived through the organosolv pretreatment methodology using a hardwood biomass, birch. Based on the above data, two process models created in the Aspen PlusTM software and the material and energy balances used to assess the economic viability of each process. The economic assessment showed more favorable economics for the noncatalytic process than the catalytic one. The lowest minimum selling price of 441.2 €/tonne was obtained for the non-catalytic process while for the catalytic obtained 683.25 €/tonne. The above values are lined up also with the literature conducted for similar operating conditions. (EN)
