(440e) Process Modeling of Fluidized Bed Biomass-CO2 Gasification Using Aspen Plus
In this work, a comprehensive model simulating the biomass gasification process using CO2 in a fluidized-bed gasifier is developed using ASPEN Plus. The model utilizes additional reactors and mechanisms simulating various steps in the gasification process to predict the effect of operating parameters such as temperature and CO2 flowrate on biomass conversion and syngas composition. A sensitivity analysis of product gas composition and a comprehensive sustainability assessment is conducted to evaluate the economic, environmental, and social performance of the biomass-CO2 gasification process.
The results from this model are compared to published gasification experimental data obtained on a bench scale fluidized bed gasifier.
