The 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.
