Co-Briquetting of Coal and Biomass

摘要

The co-briquetting of coal and biomass has been under evaluation at the University ofKentucky Center for Applied Energy Research (CAER) for the past decade. Earlystudies focused on the co-briquetting of bituminous-coal fines with sawdust but havesince expanded to include sub-bituminous and lignite coals as well as biomass from avariety of sources including agricultural wastes, energy crops, and bio-char.Co-briquetting biomass with fine coal provides an avenue for moving biomass into theenergy markets at a meaningful scale using the infrastructure now used to transport,store, and utilize coal. It can also serve to convert low-market-value coal into a loweremissionpremium fuel that is suitable for the steam or stoker markets or serve as asingle-source feedstock for gasification and/or liquid fuels production.Selected results for two prior co-briquetting projects are presented along with adescription and initial results from three current projects.
