significant synergistic effect between corn stalk and FW during co-CFP process. On one hand, because of higher H/Ceff ratio, FW could provide hydrogen for the conversion of corn stalk. On the other hand, oxygenated compounds in the corn stalk fast pyrolysis vapors could promote the chain scission and cracking of long-chain organic matter in FW (Jakab et al., 2000). Therefore, co-feeding biomass with FW could increase the overall yield of total organic pyrolysis products and relative content of aromatics.
