BACKGROUND Lignin is a highly abundant biopolymer synthesized by plants as a complex component of plant secondary cell walls. Efforts to utilize lignin-based bioproducts are needed. RESULTS Herein we identify and characterize the composition and pyrolytic deconstruction characteristics of high-lignin feedstocks. Feedstocks displaying the highest levels of(More)
Pyrolysis-GC/mass spectrometry (Py-GC/MS) and thermogravimetric analysis (TGA) was used to analyze the thermal decomposition of several endocarp sources, namely, coconut shells, walnut shells, peach pits, and olive pits, as well as their respective lignin fractions. To determine whether extraction procedures influenced pyrolysate composition and thermal(More)
