Process Design and Technical feasibility analysis of Catalytic fas tpyrolysis for biocrude production

Sammanfattning: The demand of renewable fuels is increasing. Catalytic Fast Pyrolysis is a growing technology that could supply with high quality bio crude that can be used in the already existing infrastructure. The process of choice in this paper to implement this technology is insitu circulating fluidized bed using saw dust as feed. Two cases are designed and then modelled in ASPEN Plus. The first case uses steam as fluidizer and the second uses recycled pyrolysis gas as fluidizer. Both cases are found to be self-sustainable with biomass as the only energy source. According to the parameter study, this is only true for biomass feed up to 40% moisture content.
