Material Characterization of Lignin‐Filled Polypropylene Composites

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
Ground and spray‐dried lignin powders are compared as fillers for polypropylene composites. Differences in powder preparation methods are associated with differences in powder characteristics and composite behavior after melt compounding. Spray‐dried lignin produces smaller particles and fewer large agglomerates, while a 5 wt% lignin loading provides a

Design of Atomizers and Burners for Coal-Water Slurry Combustion, Quarterly Activity Report, 1 July 1997 to 30 September 1997

, 1997
In preparation for coal-water slurry tests, a Delavan nozzle was characterized using water and a Malvern 2600 particle sizer. Actual tests using coal-water slurry failed due to phase segregation of the coal particles in the liquid supply lines and within
