Abstract:

Based on the preliminary tests of the CRIBE downdraft gasifier, that successfully operated with wood chips, wood pellets and sunflower residues, a model of the reactor and the process is developed to predict the most important process performances (syngas composition, tar content, biomass conversion, maximum temperature achieved). A commercial software (Aspen Plus®) is used to develop a detailed model and relate operating conditions, biomass characteristics and reactor parameters. Although many literature works modeled all gasifiers like equilibrium reactors, here an originally procedure is applied to evaluate the effect of the operating conditions, quantify the gasification by-products (CO2, CH4, tar), and finally optimize the gasifier performance in view of different applicative processes. A sensitivity analysis is carried out to evaluate the effect of the operating conditions and the biomass composition and predict the outputs even in ranges of operability different from those operated with the CRIBE plant. Different process configurations are studied to efficiently produce syngas, electricity, hydrogen or Synthetic Natural Gas.
