Advanced Systems: Preprocessing and Characterizing Coal-Biomass Mixtures as Next-Generation Fuels and Feedstocks
Performer: Virginia Polytechnic Institute and State University
Project No: FE0005451
The project team is developing engineered systems for manufacturing coal-biomass briquettes or pellets containing 10 to 30 percent biomass that are ideally suited for transportation, storage, and direct co-feeding into industrial gasifiers. An in-depth experimental study to determine the key reactive properties for coal-biomass mixed fuels is underway, testing sub-bituminous coal mixed with biomass feedstocks of hybrid poplar wood, switchgrass, or corn stover. Enabling technology for this project includes the application of novel binding additives and, when required, an advanced conditioning process for upstream sizing, upgrading, and drying. Upon completion, the project will provide information on the equipment, necessary conditions, and process requirements for the manufacture of optimal coal-biomass feedstock for co-gasification.
