Feedstock Development programs
Engineering Solutions For Biomass Feedstock Production
This program is developing effective and efficient engineering solutions and machinery for successful production of biomass feedstock, including pre-harvest crop production, harvesting, transport, storage and systems informatics and analysis.
The performance of sugarcane harvesters in energy cane, sugarcane and napier grass was monitored in Florida. Lower travel speeds and throughput rates, and approximately twice the energy consumption were measured with energy cane as compared to sugarcane, resulting in higher harvesting costs of $5.91 Mg-1 (wet-basis) versus $1.87 Mg-1. Real-time analysis of harvester performance generated information useful for machine management and logistics. A stem-bending yield sensor fitted to a sugarcane harvester predicted napier grass yield with 85-90% accuracy. Serrated cutting blades fitted to harvesters consumed less energy for Miscanthus and provided greater shoot emergence rates for napier grass. Greater shattering of stems was observed for energy cane compared to sugarcane.
2) Transportation of Biomass – The effect of forms, including five Miscanthus forms, three sugarcane forms and one blending feedstock, on biomass digestion were studied. The relationships among biomass electrical capacitance, bulk density, moisture content, and particle size during densification were investigated. Feasibility of secondary compression of biomass pellets was evaluated.
3) Storage of Biomass – Partial least squares regression models using FT-NIR to predict the composition (glucan, xylan, arabinan, lignin, and ash contents) of Miscanthus have been completed. A computational fluid dynamics model has been developed to predict the temperature, moisture, carbon dioxide concentration, and dry matter loss in stored Miscanthus under different conditions.
4) Systems Informatics and Analysis – A BioTraNS computer model was developed for optimal dispatch scheduling of biomass transporting vehicles. The BioScope model has been expanded to optimize the logistics from farms to the points of liquid fuel consumption. The strategic BioScope and tactical BioFeed supply chain models have been integrated. A CyberGIS-enabled biomass supply chain decision support platform has been developed.
1) Pre-harvest Crop Monitoring – Crop imaging data were collected using an unmanned aerial vehicle. A gantry sensing system was used to collect proximity data on energy crops. NDVI values of Miscanthus determined by a multispectral camera on a tower were correlated with the dry mass data manually collected by another EBI program.
2) Harvesting (of Miscanthus) – Modified disk heads on a mower/conditioner improved work rate by 37%. Angled blades lowered energy consumption of cutting by 32%. Stem bending force measured by a push bar could be used to monitor harvesting yield and control ground speed of the mower. A LIDAR sensor was mounted behind a mower to measure yield within an accuracy of 81-96%.
3) Transportation – A unifying biomass grinding law was developed for scaling up of machine parameters. Biomass Poisson’s ratios and rebounding force curves were determined. Biomass compression under very high pressure (750 MPa) was investigated. Impact of biomass forms was evaluated using dilute acid pretreatment in collaboration with the EBI chemical analysis group. Biomass mechanical preprocessing experimental data were provided to the Systems Informatics and Analysis task group as input values to its BioFeed model.
4) Storage – Biomass isotherm models have been developed for Miscanthus, energy sorghum, energy cane, and switchgrass. Equations for airflow resistance through biomass have been established for chopped Miscanthus and milled pressed energy sorghum stalks. Progress has been made to develop a regression model that correlates FT-NIR spectral signals with Miscanthus quality.
5) Systems Informatics and Analysis – BioFeed model was used to investigate biomass size reduction and compression impacts on overall supply chain costs. BioScope model was used to study the effect of dynamic demand and supply changes over time based on the Renewable Fuel Standard. Visualization tools have been developed to display the output of both models.
Ting’s team determined that, with minor modifications, existing machinery can be used to harvest switchgrass and Miscanthus. The group also determined that systems for drying corn may also be used to dry or aerate a bed of chopped Miscanthus because the airflow patterns are comparable to that of shelled corn. His group also developed a computer model, BioFeed, that optimizes more than 300,000 variables, including weather, crop yield, farm size, transportation distances, harvest schedule, and equipment selection. BioFeed found, for example, that storing the harvested grasses in a protected site on the farm would typically reduce the overall cost of the system more than if it were stored uncovered on-site, or stored at a centralized facility.
Ting established laboratories for crop monitoring, harvest, transport, storage, and systems analysis. The team also developed and tested algorithms for analysis of energy crop spectral images and conducted experiments using the biomass harvesting laboratory, instrumented mower-conditioner and bailing machinery. Other lab members measured energy requirements for biomass size reduction and compression and developed an agent-based model and a web-based decision support system.
