WebThe pyrolysis of butia seed waste (BSW) was investigated under a thermogravimetric scale at multiples heating rates (5–40 °C min −1) in a nitrogen atmosphere.First, the pyrolysis behavior of BSW was deconvoluted into four independent reactions using the Asym2Sig fitting function. The kinetic triplets (activation energies, pre-exponential factors, and … WebIn general, lignin exhibits unpredictable and nonuniform thermal properties due to the structural variations caused by the extraction processes. Therefore, a systematic …
