Abstract
Fast pyrolysis of third generation biomass, including micro- and macroalgae for biofuel production has recently been studied and compared experimentally to first- and second-generation biomass. Compared to microalgae, however, process design and simulation study of macroalgae for scale-up has been rare in literature. In this study, we designed and simulated an industrial scale process for producing diesel range biofuel from brown algae based on bench scale experimental data of fast pyrolysis using a commercial process simulator. During process design, special attention was paid to the process design to accommodate the differences in composition of brown algae compared to terrestrial biomass. The entire process of converting 380,000 tonnes of dry brown algae per year into diesel range biofuel was economically evaluated and the minimum (diesel) selling price was also estimated through techno-economic analysis.
