The optimization of biomass gasification should be studied with advanced models to evaluate the effect of the operating conditions, quantify the by-products (CO2, CH4, tar) and compare different reactor configurations. In this work different gasifiers (fixed beds, fluidized beds, entrained flow reactors) are modeled with Aspen Plus® according to an originally developed procedure. The innovative feature of the modeling procedure for all cases consists in the separation of the steps of solid fuel gasification (devolatilization,...
