Column fractionation of various pyrolysis oils (wt%).

Sample	Hexane	Toluene	Ethyl acetate	Methanol	Levoglucosan* (water sol/total)
Sand	2.6	1.3	54.5	26.6	6.7
Untr/BASF	1.8	1.8	54.0	14.5	4.3
Treat/BASF	2.2	1.8	61.4	6.6	2.4
Treat/Sudchem	1.4	2.8	58.0	11.3	4.4

*Mass (mg). (Sand: untreated wood pyrolyzed on silica sand; Untr/BASF: untreated wood pyrolyzed on BASF catalyst; treat/BASF: wood treated with sodium hydroxide and pyrolyzed on BASF catalyst; treat/Sudchem: wood treated with sodium hydroxide and pyrolyzed on Sudchem catalyst).
