the methods, systems and compositions for uniform pre-treatment of biomass in seconds with low inhibitor formation are disclosed in this document. the pre-treatment process is used to convert biomass into fuel, sugars or other useful chemicals by subjecting the raw material to a fast retention time under pressure and temperature and / or chemical reagent. the system includes, at least, a high pressure vapor impermeable plug and a continuous operation valve discharge device to discharge the pre-treated raw material, maintaining a uniform pressure in the pre-treatment system. |
