Abstract:
Lignocellulosic biomass conversion into liquid biofuels through thermochemical routes has been considered as a promising option in order to increase the share of renewable energy in the nowadays highly petroleum-dependent transport sector. This study presents the conceptual process design for the production of Fischer-Tropsch (FT) liquids from syngas derived from Chemical Looping Gasification (CLG). The main advantages of CLG compared to the most common gasification technologies is the avoidance of an expensive and energy-consuming Air Separation Unit (ASU), the wide feedstock flexibility and the light biomass handling before gasification. Process simulations of the overall system for multiple feedstock are performed, investigating the potential of a self-powered Biomass to Liquid (BtL) plant with integrated refinery concept in comparison with a non self-powered BtL plant with separate refinery concept. The main objective is to perform the energy and mass balance calculations and to determine the appropriate process configuration. The model development and the process simulations were carried out with Aspen PlusTM. Depending on the feedstock type and heat integration approach, carbon utilization factors between 31 and 35 % and energetic fuel efficiencies between 43 and 48 % were calculated on the basis of the obtained energy and mass balances.
