  • Cellulose pretreatment process
    Patent number: 8287651
    Abstract: A process for the production of ethanol from biomass is disclosed. The process relates to the pretreatment of corncob biomass and includes the steps of exposing corncob to steam in a reaction vessel at an elevated temperature and reaction pressure for a preselected exposure time. Volatile compounds are continuously vented during pretreatment. The reaction pressure is released for explosive decomposition of the corncob biomass into fibrous solids and condensate. The exposure is preferably carried out at a temperature of 190-210° C. and a pressure of 190 psig to 275 psig and an exposure time of 3 to 10 minutes.
    Type: Grant

    Assignee: GreenField Ethanol Inc.
    Inventors: Robert Benson, Chris Bradt, Regis-Olivier Benech, Richard Romeo Lehoux
  • REMOVAL OF INHIBITORY COMPOUNDS DURING PRE-TREATMENT OF LIGNOCELLULOSIC BIOMASS
    Publication number: 20100181034
    Abstract: A process for the pretreatment of lignocellulosic biomass, in particular during the production of ethanol from biomass. The process including a cooking step where the biomass is exposed to steam at elevated temperatures and pressures for a preselected period of time in a treatment vessel. During the process, volatile and liquid compounds are purged from the treatment vessel.
