Abstract

A method and apparatus for preparing a cellulosic feedstock are disclosed. Embodiments of the method comprise obtaining a cellulosic feedstock having a moisture content of 30 wt % to 60 wt %; passing the cellulosic feedstock through a heated holding tank; withdrawing the cellulosic feedstock from the holding tank; and, subsequently subjecting the cellulosic feedstock to hydrolysis. Embodiments of the apparatus comprise at least one sidewall defining a volume having an upper portion and a lower portion. At least one inlet is provided adjacent the upper portion, and the inlet is in fluid communication with an impregnation chamber provided upstream from the holding tank. At least one outlet is provided adjacent the lower portion, and the outlet is in fluid communication with hydrolysis reactor positioned downstream from the holding tank.
