Abstract Biomass has potential as a carbon-neutral alternative to petroleum for chemical and energy products. However, complete replacement of fossil fuel is contingent upon efficient processes to eliminate undesirable characteristics of biomass, e.g., low bulk density, variability, and storage-induced quality problems. Mechanical size reduction via comminution is a processing operation to engineer favorable biomass flowability
Abstract Lignocellulosic biomass has a complex, species-specific microstructure that governs heat and mass transport during conversion processes. A quantitative understanding of the evolution of pore size and structure is critical to optimize conversion processes for biofuel and bio-based chemical production. Further, improving our understanding of the microstructure of biochar coproduct will accelerate development of its
Abstract Roundwood logs from forests and energy plantations must be chipped, ground, or otherwise comminuted into small particles prior to conversion to solid or liquid biofuels. Results & discussion: Rotary veneer followed by cross-grain shearing is demonstrated to be a novel and low energy consuming method for primary breakdown of logs into a raw material

Abstract Comprehensive models for grain drying have been derived using critical data available from literature dating back to Shedd’s 1953 work on pressure drop. Although dryer design data for grains and many industrial materials are known, Forest Concepts has developed data and evidence that biomass feedstocks are sufficiently unique that published design data is not

Abstract Forest Concepts, with funding from USDA NIFA SBIR program, developed methods and equipment to reprocess low-value dirty forest chips, tree service chips, and hog fuel into high value clean wood fiber and other valuable fractions. Traditional clean sources of mill residuals (sawdust, shavings, and chips) are declining rapidly due to improved sawmilling efficiencies and

Abstract We have an objective to convert cellulosic biomass raw materials into small particles that are optimized for biochemical and/or thermochemical conversion to liquid transportation fuels. As a side effort, we are interested in producing feedstocks for composite bioproducts, solid biofuels, and other uses. Wood chips that have a typical length of 50mm are a

Abstract Under funding from DOE Office of Biomass Programs, engineers at Forest Concepts are working to apply low-energy comminution methods to produce improved biomass particle geometry and sizes optimal for biochemical and thermochemical conversion to liquid transportation fuels. Designs are constrained to concurrently achieve the DOE Uniform Feedstock Format criteria for bulk handling and flowability.

Abstract In an earlier ASABE paper, Buckmaster reported that ion conductivity of biomass leachate in aqueous solution was directly correlated with activity access to plant nutrients within the biomass materials for subsequent biological or chemical processing. The Buckmaster test involves placing a sample of the particles in a beaker of constant-temperature deionized water and monitoring

Abstract Specific energy for comminution and mechanical processing of lignocellulosic feedstocks provides an economically important basis to compare equipment and to provide data for lifecycle analysis of complete systems. Measurement of specific energy during equipment design and development activities enables optimization of design parameters. Forest Concepts developed a torque-arm apparatus and LabView data acquisition method
