Description
University of Kentucky Center for Applied Energy Research (UK CAER) proposes utilization of an
existing DOE-funded 1 ton/day coal gasification unit and high pressure extruder operated on the UK
CAER campus to develop a densified biomass-plastic fuel with a surface area less than 50 m2/m3 that is
suitable for oxygen-blown entrained flow gasification with slurry feed. The developed fuel will be
characterized and evaluated for heating value; grindability; slurryability; gasification kinetics; slag
formation and behavior; and syngas composition. To meet this main objective, three approaches will be
evaluated for effectiveness at lab-scale with (1) applying compact force via mechanical presser on
selected torrefied biomass (bio-char) to crush the porosity by 50%, increase the density and block the
micropore structures eliminating water capillary effect; and (2) spray coating a hydrophobic layer on
pressed steam exploded pretreated pinewood to reduce water intake during the coal-biomass-plastic slurry
production; and (3) co-extruding pretreated pine wood with plastic as binder and fluidizing agent to
produce a compacted mixture with biomass coated by hydrophobic plastic. Upon a perforable production
process being identified, approximately 400 lb. biomass-plastic fuel will be prepared for lab-scale
grindability and slurryability study, and tested in the UK CAER opposed multi-burner, entrained flow
gasifier for investigation on carbon conversion, fuel behavior, syngas composition and slag
characterizations.
