Process for pre-hydrolysis of biomass

摘要: This invention refers to a process carried out in an apparatus for the processing of pre-hydrolysis biomass, particularly reactor failsafe type, either mobile or not, which may be manufactured microbonded carbon steel and coated with special materials (refractory metals, superalloys, stainless materials, plastics, etc.). The insertion vacuum between shell its coating prevents implosion permits detection leakage helium gas. resistance corrosion refractory metals enables carrying mineral digestion. In this invention, biomass is compacted at 300 kg/m3 by helical feeder, degased, flooded, heated, stirred, pre-hydrolyzed, sugar being recovered first washing within values higher than 90 %. low liquid/solid ratio = 2 one achieve content 10 bricks prehydrolysate consumption % energy contained processed biomass. pre-hydrolysate constituted solutions xylose others intended production furfural, alcohol xylitol. control produce cellulignin high specific surface, m2/g (measured BET), compared value 0.4 nonhydrolyzed maintain crystallinity cellulose fibers, aiming grinding it into fine particles (f<)250 mm), globulizing lignin, exposing attacks microorganisms from cud ruminants, fungi, bacteria enzymes microbiological enzymatic fermentation. catalytic combustion due large surface results new fuel boilers, combustors general MHD when produced filtered water, gas turbines deionized water.
