Production of aromatic hydrocarbons through catalytic pyrolysis of 5-Hydroxymethylfurfural from biomass

Catalytic pyrolysis of 5-Hydroxymethylfurfural (HMF) was conducted on a fixed bed reactor at atmospheric pressure. HMF could be converted into aromatic hydrocarbons through catalytic pyrolysis . The catalysts and reaction conditions were both critical in maximizing the aromatic hydrocarbons selectivity . Four catalysts, β-zeolite, HZSM-5, Ga/HZSM and In/HZSM were tested in this study. HZSM-5 (Si/Al   =   50) was found to be the most effective catalyst in both reactivity and selectivity among these catalysts. Under the reaction temperature of 600   °C, the highest carbon yield of 48.99% of aromatic hydrocarbons was achieved from catalytic pyrolysis HMF with HZSM-5 (Si/Al   =   50) as catalyst. Moreover, the HZSM-5 (Si/Al   =   50) catalyst was recycled for five times without shown deactivation of the catalyst.
