| Outline of Final Research Achievements |
The effect of pyrolysis temperatures on the product distribution in reforming of nascent volatiles derived from cellulose fast pyrolysis over HZSM-5 was studied. A two stage tubular reactor at which first and second stages were designed for fast pyrolysis of cellulose and catalytic reforming of volatiles, respectively, was originally developed. Significant features of the experimental setup include that the temperatures of the two stages can be controlled independently and that the products can be analyzed exhaustively by the direct injection of analytes into gas chromatographs. At low pyrolysis temperature, cellulose produced oxygenated compounds that were converted almost completely over HZSM-5 accompanying dehydration and formations of important precursors of aromatic hydrocarbons such as alkyne and dienes. When pyrolyzed at high temperature, the oxygenated compounds are no longer produced, indicating that olefins such as ethylene are dominant precursors of aromatic hydrocarbons.
