Abstract

In order to utilize biomass as new resources of petrochemicals, catalytic conversion of oxygen-containing intermediates which can be derived
from biomass was investigated. By using ZSM-5 as the catalyst, ethylmethylketone was converted to aromatic and aliphatic hydrocarbons at
high yields. Selectivity for aromatics was found 70 – 80 %, and the major components were xylene and toluene. Selectivity for aliphatics was
about 25 %, and the major components were olens such as propylene, butene and ethylene. The formation of CO2 and CO was only 2 –3 %.
When acetone, acetaldehyde, propionaldehyde, levulinic acid were used as the feed materials, similar results were obtained.
