Feedstock PDU 2013  

Bench-to-Pilot-Scale Production

Today's biomass conversion processes require specific feedstocks specifications that differ considerably among the various conversion pathways:

  • Biochemical conversion pathways generally perfer herbaceous or hardwood biomass milled to intermediate mean particle sizes typically ranging from 6-50 mm.
  •  Pyrolysis requires a finely milled feedstock, typically less than 2 mm.
  • Gasification can have a wide range of particle size specifications depending on the specific gasification technology.
  • Combustion via co-firing with coal favors woody bio-mass that has been chipped and torrefied followed by fine-milling to produce a fine, coal-like feedstock.

In each case, tight tolerances on the particle-size distribution and precise preprocessing conditions are required.

Feedstock Development

The BFNUF feedstock PDU provides access to a range of biomass resources and preprocessing capabilties to produce virtually any feedstock, any specification, at any scale.

Process Development

The Feedstock PDU capabilities are grouped into five categories, with a variety of equipment types and sizes available in each: size reduction, separation/fractionation, thermal treatment, chemical treatment, and densification.

System-Level Solutions

A unique capabiltiy of the Feedstock PDU is to test and develop fully integrated and instrumented industrial-scale preprocessing systems. Continuous processing and data collection enables:

  • Identifcation of preprocessing bottlenecks.
  • Exploration of the interaction and synergies of preprocessing operations affecting feedstock specifications and conversion performance.
  • Optimization of integrated preprocessing systems.
