Digestate, the residue following of anaerobic digestion, had attracted great attention recently as potential feedstock of pyrolysis. The results of component analysis verified that digestate was suitable for phenol production due to its considerable lignin content. The thermal degradation of lignin in digestate mainly occurred around 350–450 °C in thermogravimetric analysis. The amorphous cellulose...
The main components in bio-oil behave differently during the thermal treatment in water or in methanol. Water cannot stabilize the aromatics in bio-oil. Consumption of the aromatics with mono-ring and two fused benzene rings and the formation of the aromatics with three or more fused benzene ring aromatics were observed during the thermal treatment in water. In methanol, the fluorescence intensities...
Coffee is an important agricultural product being one of the most consumed beverages in the world. The goal of this work is to apply the pyrolysis to this residue for the production of bio-oil. The pyrolysis of the biomass (SCG) was done in a fixed bed reactor and varying the final temperature (400, 450, 500, 550 and 600 °C). The higher crude bio-oil yield was obtained at 500 °C with a flow of N2...
