Abstract

A model to simulate the entrained flow gasification process to produce a syngas useful in the synthesis of liquid biofuels and/or chemicals was developed. The model is simulated in Aspen Plus and includes the stages of: pretreatment and conditioning of biomass (drying, torrefaction and grinding), entrained flow gasification, cleaning and conditioning of syngas produced, adjustment of H2/CO relation, and an Air Separation Unit (ASU) for oxygen production as gasifying agent. The model validation was performed from experimental data reported in the literature, by analyzing the relative errors for the interest variables: H2/CO, lower heating value and cold gas efficiency, founding errors of 7.8%, 11.8% and 8.8% respectively. Additionally, the sensibility of the model to predict the effect of process variables as torrefaction temperature and equivalence ratio on response variables, showed similar tendencies to those found.
