Abstract: A method and system for preparing biomass for biotreatment in a static solid state bioreactor is performed in two stages. The first stage includes pre-mixing of the biomass with one or more reagent(s). The second stage includes the addition of a bulking agent to the pre-mixed biomass after a time sufficient for the reagent(s) to have reacted with the biomass. The second stage also includes mixing of the added bulking agent with the pre-mixed biomass to produce a biomass batch suitable for forming a static solid state particle bioreactor.

Abstract: A continuous biomass pretreatment system and method is provided. The system comprises a pipe reactor having an input end, an output end, an interior and an exterior. The pipe reactor does not have a mixing component that passes from the interior to the exterior and rotates with respect to the pipe. The system further comprises a pump in communication with the input end of the pipe reactor, a valve in communication with the output end of the pipe reactor, and a flash vessel having an input opening in communication with the output of the valve.
