Effect of furans on particle formation in diffusion flames: An experimental and modeling study

Modeling analysis showed that 2-methylfuran produces large amounts of C4-species and thus benzene and polycyclic aromatic hydrocarbons (PAHs). 2,5-dimethylfuran mainly forms phenol during its decomposition, which leads to cyclopentadiene and thus naphthalene formation. However, in the operating conditions analyzed in this study the overall PAHs and first particle production result less strong than in 2-methylfuran. However, different combustion conditions can change the effectiveness of these channels and might invert the particle production tendency of furanic fuels.
