correlation of feedstock with bio-oil compound distribution
was explored with straw, shell, woody, and algae biomasses. The pyrolysis
of 20 typical feedstock samples were performed using Pyrolysis–gas
chromatography/mass spectrometry (Py–GC/MS) with a final temperature
of 550 °C, heating rate of 10 000 °C/s, and residence
time of 10 s. Biomass samples share a common characteristic, such
as high oxygen and low nitrogen and sulfur, which is different from
coal. The results revealed that there is a strong positive correlation
between ketones and cellulose, furans and holocelluose, and phenols
and lignin but a negative correlation between short-chain acids and
ash content and hydrocarbons and cellulose. Woody biomass produced
higher phenols; straw biomass produced high ketones; shell biomass
produced high furans; and algae produced high fatty acids. However,
some special points showed that Enteromorpha algae produced high furans and tobacco stems produced high N-containing
compounds.
