Chemical Looping Gasification for Hydrogen Enhanced Syngas Production in the Reaction Mixture Carbon Dioxide Capture

Performer: Ohio State University

Project No: FE0012136

Project Scope and Technology Readiness Level

The goal of this project is to improve the current oxygen carrier particle performance and CLG reactor system design for the coal to liquid (CTL) processes. Improvements in the oxygen carrier particle reactivity, selectivity, and recyclability will be made via modification of particle composition and synthesis methods. The optimum particle performance and optimum operating conditions for the reducer and oxidizer such as the temperature, gasification enhancer type, and flow rate will be identified in Thermogravimetric Analyzer (TGA) and small fixed bed studies. The bench scale demonstration will be conducted with both working and improved particles. Different ranks of coal such as bituminous, sub-bituminous, and lignite will be tested. Fates of sulfur, nitrogen and ash will be determined. Sub-pilot cold flow model studies will be conducted to de-risk the unknowns of the hydrodynamics for future scale-up developments. Different CLG systems will be designed to optimize the CTL processes. Comprehensive Aspen Plus process simulations and economic analyses will be completed based on the project results. The techno-economic analysis will be conducted to evaluate plant efficiency, cost and environmental performance of adopting CLG technology into a commercial scale methanol and/or Fischer-Tropsch diesel production plant. It is expected that the optimal CLG process will be selected and ready for further scale up upon completion of the proposed one-year project.

The Technology Readiness Level (TRL) assessment identifies the current state of readiness of the key technologies being developed under the DOE's Clean Coal Research Program. This project has not been assessed.

The TRL assessment process and its results including definition and description of the levels may be found in the "2012 Technology Readiness Assessment-Analysis of Active Research Portfolio".
