Methods for regenerating acidic ion-exchange resins and reusing regenerants in such methods |
| 摘要 |
Methods for regenerating acidic ion-exchange resins and reusing regenerants in such methods are provided. A spent ion-exchange resin is contacted with an alcohol ion-exchange regenerant. The spent ion-exchange resin is thereafter contacted with an acidic ion-exchange regenerant to recharge the acidic ion-exchange resin to produce a regenerated acidic ion-exchange resin. Metal- and water-containing biomass-derived pyrolysis oil is then contacted with the regenerated acidic ion-exchange resin to produce low metal, water-containing biomass-derived pyrolysis oil. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled. |

1. A method for the regeneration of a spent acidic ion-exchange resin and recycling thereof comprising:
contacting the spent ion-exchange resin with an alcohol ion-exchange regenerant consisting of an alcohol; thereafter contacting the spent ion-exchange resin with an acidic ion-exchange regenerant to recharge the acidic ion-exchange resin to produce a regenerated acidic ion-exchange resin; and contacting a metal- and water-containing biomass-derived pyrolysis oil with the regenerated acidic ion-exchange resin to produce a low metal, water-containing biomass-derived pyrolysis oil. |
