  • Patent number: 8641910
    Abstract: Systems and processes for converting bulky lignocellulosic biomass to high density biomass products, including biofuels, are described. The systems and processes relate to treating freshly harvested plant materials, generally at or in close proximity to sites where the plant materials are harvested, to effect saccharification, alcoholic fermentation, or simultaneous saccharification and fermentation, thereby providing a liquefied biomass. The liquefied biomass is extracted to provide liquid extracts comprising biomass-derived water and water soluble biomass saccharification and fermentation products, including fermentable sugars and alcohols. The liquid biomass extracts can be transported via pipeline to other locations for fermentation, further saccharification, and/or purification to provide biofuel. Alternatively, the liquefied biomass can be used to prepare a biomass slurry that can be transported via pipeline.

  • Publication number: 20070005186
    Abstract: An apparatus and method is provided for coordinating automated package and bulk dispensing at a remote site. A hopper apparatus includes a series of storage compartments and access doors. The compartments and doors are linked to a PLC that is further linked to an inventory provider. The inventory provider takes product orders from an end-user. The end-user is provided an end-user access code. The inventory provider communicates with the PLC and reserves for the ordered product(s) a vacant storage compartment(s). The inventory provider delivers the product(s) ordered by the end-user to the hopper apparatus. Upon delivery, the inventory provider enters the appropriate end-user access code(s), causing the PLC to open the storage compartment(s) previously reserved by the inventory provider for the products ordered by the end-user. The inventory provider loads the appropriate storage compartment(s) with the end-user product(s).
