摘要： A method and apparatus for conveying a cellulosic feedstock are disclosed. The apparatus, such as a holding tank, has a passage. At the outlet to the passage, a conveyance member is provided to convey the cellulosic feedstock laterally across the outlet. The conveyance member, e.g., at least one screw conveyor, may have a variable pitch along its length. The method comprises passing the cellulosic feedstock through an impregnation chamber to an outlet of the impregnation chamber; passing the cellulosic feedstock from the outlet of the impregnation chamber to an inlet of a holding tank; passing the cellulosic feedstock downwardly through the holding tank; maintaining a generally constant residence time in the holding tank; and subsequently subjecting the cellulosic feedstock to a hydrolysis process.

摘要： A method and apparatus for treating a cellulosic feedstock, such as for subsequent ethanol production, are disclosed. The method comprises determining an initial moisture content of the cellulosic feedstock and adding an amount of moisture to the cellulosic feedstock to obtain a predetermined moisture content of the cellulosic feedstock, wherein the cellulosic feedstock may subsequently be subjected to hydrolysis. The apparatus comprises a moisture sensor that provides an initial moisture content reading of the cellulosic feedstock, and a weight sensor providing the weight of the cellulosic feedstock. A processor is configured to determine an amount of moisture to be added to the cellulosic feedstock based on the weight and the initial moisture content of the cellulosic feedstock to obtain treated cellulosic feedstock having a predetermined moisture content.
