| Popis: | Among the different biomass conversion technologies, biomass to liquid (BtL) process, using cheap lignocellulosic materials, can produce high quality fossil-like fuels. Thermochemical conversion processes consist mainly in pyrolysis, gasification, liquefaction and supercritical fluid processing, by which biomass can be converted into syngas, bio-oil, char and gaseous products. From these, bio-oil can be used as an intermediate step to convert it into higher energy-dense transportation liquid fuels such as diesel and gasoline. In this study, we introduced a process synthesis framework for the conversion of woody BtL transportation fuels, where we evaluated promising thermochemical and upgrading technologies and adapted into a superstructure based on experimental data from literature. In the model, woody biomass was represented by Spruce. The process simulator Aspen Plus V8.8 and Aspen Economic Evaluation V8.8 were used to predict the energy consumption and equipment cost of the unit operations. From the multiple paths, the process flowsheet of Gasification-Low Temperature Fischer-Tropsch-hydrotreating-hydrocracking and final fractionating units was among the most cost-effective under different scenarios. The novelty of this work relies on the synthesis of a superstructure of the combined thermochemical conversion and upgrading technologies specifically for woody BtL fuels, as well as the use of rigorous simulations to predict thermodynamic properties, energy consumption and equipment designs and costs for the superstructure’s units operations. |
