The NREL system is comprised of a fluidized-bed fast pyrolysis unit\nand a fluidized-bed vapor phase upgrader for thermochemical conversion of\nbiomass to bio-oil. More information about the NREL 2FBR system is available\nat [ccpcode.github.io/docs-2fbr/][2fbr] and [cpcbiomass.org][ccpc].\n\n[2fbr]: https://ccpcode.github.io/docs-2fbr/\n[ccpc]: https://www.cpcbiomass.org\n\nSieve measurements of the particles were conducted at UTK. Analyses of the\nparticles were performed by [Galbraith][gal]. Size measurements of the\nparticles were performed by [Microtrac][mic]. A summary of each folder in this\nrepository is provided below.\n\n[gal]: http://galbraith.com\n[mic]: https://www.microtrac.com\n\n**code** - This folder contains Python code provided as Jupyter notebooks or\nindividual scripts for analyzing data from the sieve measurements, Galbraith\nanalysis, and Microtrac measurements.\n\n**data** - Data files for the sieve measurements, Galbraith analyses, and\nMicrotrac measurements. There is also a spreadsheet from NREL with various\nanalysis results. Galbraith provided a PDF of their analyses which was used to\ncreate an Excel spreadsheet and CSV file. Microtrac provided their\nmeasurements as Excel spreadsheets which were used to create the CSV files.\nSieve measurements were recorded by hand then entered into CSV files.\n\n**results** - Plots generated from the code files and Jupyter notebooks.\n\n## NREL 2FBR bulk samples\n\nThe samples listed below were obtained from the NREL 2FBR system from a single\nexperiment.
