Abstract
Low metal, low water biomass-derived pyrolysis oils and methods for producing the same are provided. Metal- and water-containing biomass-derived pyrolysis oil is contacted with an acidic ion-exchange resin having sulfonic acid groups to produce a low metal, water-containing biomass-derived pyrolysis oil. The low metal, water-containing biomass-derived pyrolysis oil is removed from the spent ion-exchange resin after ion-exchange. The low metal, water-containing biomass-derived pyrolysis oil is distilled to produce a low metal, low water biomass-derived pyrolysis oil and a distillation product. The distillation product comprises one or both of an alcohol ion-exchange regenerant and an acidic ion-exchange regenerant which may be used to regenerate the spent ion-exchange resin. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.
