%X In preparation of motor fuel, bio-oil from pyrolysis of biomass must be further upgraded so as to improve its quality. Upgrading operation via catalytic cracking was carried out in a tubular fixed-bed reactor with HZSM-5 as catalyst, under atmospheric pressure, in the temperature range of 340~420oC, and at weight space velocity (WHSV) of 2.9~5.6 h-1. The effects of process parameters such as temperature, WHSV, solvent and size of catalyst pellets on product yield were studied. The results show that 44.68% (w) of organic distillate was yielded at temperature 380oC and WHSV=3.7 h-1. In addition, the analysis of upgraded oil shows that the amount of oxygenated compounds in the bio-oil, such as organic acid, aldehyde, ester, alcohol, ketone were greatly reduced meanwhile aromatic and polyaromatic hydrocarbons were formed.
