Description/Abstract This report covers progress made during the period of 1 January 1986 to 31 December 1986 on the upgrading of oxygenated, primary pyrolysis oil vapors made from wood, to a high octane gasoline consisting primarily of toluene, xylenes, and trimethyl benzenes.^Rapid screening tests, involving a fixed-bed of a few grams of catalyst, were performed in real time with the molecular-beam mass-spectrometer (MB/MS).^The MB/MS work showed that HZSM-5 in extrudate form was significantly better in producing aromatic gasoline from the pyrolysis vapors than silicalite, HY zeolite, or silica-alumina.^The effect of temperature in the 300/degree/ to 500/degree/C range on the reactions was shown to dealkylate the gasolines and to increase the naphthalene yield, although overall yields appeared to be higher with increased temperatures.^A slipstream of the pyrolysis vapors made in SERI`s vortex reactor was passed through fixed beds of catalyst containing between 100 and 300 grams of HZSM-5 extrudate.^The collected condensate was analyzed by GC-FID and confirmed the gasoline product quality predicted by the MB/MS rapid screening tests.^Coke formation on the catalyst suggests this process is analogous to catalytic cracking of heavy petroleum fractions in a modern refinery rather than to the relatively coke-free methanol-to-gasoline process.^Very preliminary economics are presented which indicate the potential to produce gasoline for $1.25 to $1.50 per gallon with successful development of this wood-to-gasoline process.^66 refs., 34 figs., 9 tabs.
