| Summary: | The development of bio-based products for substituting petroleum-based products has received much attention due to environmental concerns. Hydrogen is an important chemical feedstock and energy carrier that can be derived from agricultural residue. Gasification is a thermochemical process that can convert biomass into syngas (H2+CO), while sorption-enhanced water gas shift (SEWGS) is a promising technology used to produce H2 and simultaneously separate CO2 in the same time. However, high energy is required for CO2 compression and storage. This study proposes the integration of biomass gasification and SEWGS coupled with CO2 utilization via reforming. The effect of key technical parameters, i.e., reforming reactors and percentage of recycled CO2, on H2 yield, system energy efficiency and H2/CO ratio of synthesis gas generated from reformers, are investigated. The correlation between key parameters and process performance is modeled through Aspen Plus process simulation program. Parametric analysis indicates key factors affecting syngas yield and overall energy efficiency with enhanced CO2 utilization. A performance comparison between gasification-SEWGS coupled with two different types of reforming (dry reforming and tri-reforming) using CO2 as a co-reactant is discussed, indicating the process with the highest H2 purity and overall energy efficiency. |
