Study the influence of sorbent (CaO) on hydrogen production from biomass gasification in different conditions: using ASPEN Plus

Abstract

This work models and simulates in Aspen plus the effect of influence CaO on the production of hydrogen from wood chips gasification under various operating circumstances such as temperature and equivalent ratio. The suggested quasi-steady state model, based on available experimental data, includes pyrolysis, tar cracking, and char conversion. The prediction of the resulting model is validated. The greatest H2 mole fraction with CaO is roughly 35% at temperatures close to 900 K.
