| Research Abstract |
Characteristics of in-situ catalytic reforming of the products derived from fast pyrolysis of biomass were studied with an originally designed analytical pyrolysis technique. The volatile products derived from biomass as well as synthetic cellulose, xylan, and lignin were converted using a two-stage tubular reactor at 550 oC over various zeolite catalysts. HZSM-5 exhibited a best performance in converting the biomass into aromatic hydrocarbons with the selectivity of 26% on feedstock carbon basis. The HZSM-5 had a significant effect for cellulose, showing that more than 30% of carbon in cellulose was converted into aromatic hydrocarbons. A reaction pathway analysis for reforming of volatiles suggested that alkyne and diene such as acetylene, propyne, and cyclopentadiene are the important precursors of the major aromatic hydrocarbon products such as benzene, toluene, and naphthalene. The formations of those intermediates were also confirmed experimentally.
