Characterization of Pyrolytic Sugars in Bio-Oil Produced from Biomass Fast Pyrolysis

Pyrolytic sugars from cellulosic biomass.

Depolymerization of cellulose offers the prospect of inexpensive sugars from biomass. Breaking the glycosidic bonds of cellulose to liberate glucose has usually been pursued by acid or enzymatic hydrolysis although a purely thermal depolymerization route to sugars is also possible. Fast pyrolysis of pure cellulose yields primarily the anhydrosugar levoglucosan (LG) whereas the presence of natur...

Characterization of Bio-oil from Palm Kernel Shell Pyrolysis

Pyrolysis of palm kernel shell in a fixed-bed reactor was studied in this paper. The objectives were to investigate the effect of pyrolysis temperature and particle size on the products yield and to characterize the bio-oil product. In order to get the optimum pyrolysis parameters on bio-oil yield, temperatures of 350, 400, 450, 500 and 550 °C and particle sizes of 212–300 μm, 300–600 μm, 600μm...

Characterization of Bio-Oil, Syn-Gas and Bio-Char from Switchgrass Pyrolysis at Various Temperatures

Pyrolitic conversion of lignocellulosic biomass, such as switchgrass and other agricultural residues, to bio-fuels is being considered for national energy security and for environmental advantages. Bio-oil, syngas and bio-char were produced and characterized from switchgrass at 400, 500 and 600 0C by pyrolysis. Bio-oil yield increased from 22 to 37%, syn-gas yield increased from 8 to 26%, and b...
