Abstract
It has been shown in earlier work that good conversions of the cellulose in wood to anhydrosugars can be obtained in fast pyrolysis by suitable pretreatments of the wood. Further results are now given to show the effects of operating conditions in a fluidized bed reactor on sugar yields from poplar wood which had been subjected to a dilute acid prehydrolysis to remove hemicelluloses.
Modification of the solids in the bed by the use of additives had some effect on the relative yields of gas/liquid/char but did not improve sugar yields from deionized wood. Additional results are given for yields of anhydrosugars from deionized softwood. Anhydrosugars derived from hemicelluloses are shown to be mainly anhydroxylose from hardwood and anhydromannose from softwood.
