Purdue University receives grant from DOE to minimize blockages in lignocellulosic biorefineries



Type of post: NEWS IN BRIEF.

Materials handling issues are very important in being able to scale up technology for converting cellulosic feedstocks into ethanol. Lignocellulosic biomass often accumulates and compacts while moving through augers, forcing costly shutdowns for cleaning and repairs. A research team will receive a grant from the U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) to solve that kind of problems (see press release, 29/5/2018).

Project data
Goal
To transform solid biomass into a slurry that can act more like a liquid flowing freely through material transportation systems in biorefineries.
Methodology
- To create models to predict the physical properties necessary for a liquid-like flow of solid materials.
- To create regime maps for robust operation, which would tell engineers and operators how to adjust screw feeder and reactor operating parameters
- To develop methods for modifying the biomass to meet the models’ specifications, changing particle size, shape and charge.
Feedstocks
Researchers will start with corn stover.
The work could be the foundation to develop similar technology for other biomass products as wood chips, soybean hulls and wheat straw.
Leader
- Departments of Agricultural and Biological Engineering, Mechanical Engineering and Materials Engineering
- Discovery Park Energy Center
- Laboratory of Renewable Resources Engineering (LORRE)
- Center for Particulate Products and Processes (CP3)
Partners
National laboratories:
- Argonne National Laboratory
- Idaho National Laboratory
Industrial partners:
- Forest concepts
- AdvanceBio systems
Grant
1.8 M$.
The total funding will amount to 2.3 M$ with cost share from partners.
