- Abstract:
- ... Sweet sorghum's high yielding ability, low-input demands and tolerance to stresses, render it highly suitable for syrup and bioenergy production. Exploiting its biomass, however is hampered by the seasonality of its production and the rapid post-harvest sugar catabolism degrading biomass quality. We aimed at elucidating aspects of sweet sorghum’s metabolism at different developmental and post-harv ...

Fast pyrolysis of corn stalk (CS) was performed by pyrolysis–gas chromatography/mass spectrometry (Py-GC/MS) and the product distribution was measured as a function of temperature, time, and catalyst. The types and yields of product compounds were influenced dramatically by temperature, while the duration of the reaction had little effect on the type of compound. Three primary components in the bi ...

- Abstract:
- ... Pyrolysis products derived from Fischer Assay pyrolysis at 520 °C, 720 °C and 920 °C of fine coal discards agglomerated with the addition of microalgae biomass, are reported. The process produces coal char, volatiles in the form of tar and gas, and water that is removed using a Dean-Stark distillation setup. The various char, tar and gas fractions were characterised using proximate and ultimate an ...
