Abstract: Aromatic hydrocarbons are important chemical feedstock. Conventional pyrolysis of biomass is difficult to generate aromatic hydrocarbons in large quantities. Whereas, catalytic pyrolysis of biomass, which can improve the yield of aromatic hydrocarbons remarkably, is expected to provide a new method for preparation of aromatic hydrocarbons. This paper expounded the formation mechanisms of aromatic hydrocarbons from pyrolysis of biomass, i.e., aromatic hydrocarbons from holocellulose through depolymerization, ring opening and aromatization; aromatic hydrocarbons from lignin mainly through phenolics. Also, the effects of biomass materials, catalysts, pretreatments and catalytic conditions on formation of aromatic hydrocarbons were discussed. Optimization scheme of process parameters for aromatic hydrocarbons preparation from biomass pyrolysis was proposed.

Key words: aromatic hydrocarbons, biomass, catalytic pyrolysis
