This study is to analyze a novel chemical looping (CL) syngas upgrade loop within a gasification system for the production of high-quality syngas from biomass. The system includes two reactors: one for biomass gasification and the other one for syngas upgrading with an oxygen carrier. We also recycle CO2 directly into the gasifier as a co-gasifying agent. We are developing an Aspen Plus models for techno-economic analysis of producing Fischer-Tropsch liquids via biomass gasification using this novel CL technology. The process models will be validated by experimental data and used to investigate the energy efficiency, productivity, and energy and material flows of the integrated CL biomass gasification system with various process configurations for producing syngas at various qualities from various biomass feedstocks. An economic model will be developed and incorporated into the process model to determine the cost of the CL system at different production scales. We are also building life cycle assessment (LCA) models in GaBi and OpenLCA for evaluating environmental impacts of the biorefinery.
