Hybrid Molten Bed Gasifier for High Hydrogen (H2) Syngas Production

Project Description

The GTI research team will evaluate and test a hybrid molten bed (HMB) gasification process for producing syngas from a coal/natural gas feed. The HMB gasification process potentially offers several benefits over conventional gasifiers including higher efficiency, higher yield of electricity or diesel, lower cost of electricity or diesel, lower costs for carbon capture, and lower capital costs due to simpler plant layout. The project team will conduct techno-economic analyses for plants based on conventional slagging gasification and HMB gasification producing both power and diesel and including carbon capture.

Program Background and Project Benefits

This Gas Technology Institute project is conducting techno-economic evaluations and laboratory testing of a hybrid molten bed (HMB) gasification process with coal and natural gas co-feeding to produce syngas with high hydrogen to carbon dioxide ratio. HMB gasification has the potential for improvement in operational performance and reliability of advanced coal-based power and liquid fuels generation compared to conventional gasification processes. Lowered cost and increased performance of high hydrogen syngas production would enable liquid fuels production or power generation with decreased cost and lower environmental emissions.

Project Scope and Technology Readiness Level

The project includes three major activities. First, the HMB gasifier will be modeled to determine performance, syngas yield, and syngas composition data needed for the techno-economic analyses in both integrated gasification combined cycle (IGCC) and Fischer Tropsch (FT) diesel configurations. Second, the HMB gasification process will be tested, and the performance and product syngas data needed to support the techno-economic analysis and to provide support for the next stage of HMB gasification process development will be collected. Finally, techno-economic analyses will be performed for an IGCC plant with carbon capture and an FT plant with carbon capture using both a conventional slagging gasifier and the HMB gasifier. Analyses will include baseline cases and parametric calculations to develop optimized HMB plant configurations.

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".
